description: Pythium spp. are the most common pathogens associated with soybean damping-off in the United States. The diversity of Pythium spp. recovered is extensive and the relative pathogenicity or aggressiveness of species common across states has varied among studies. We compared the aggressiveness and fungicide sensitivity of 118 isolates of four Pythium spp. (P. lutarium, P. oopapillum, P. sylvaticum, and P. torulosum) from 11 states (AR, IA, IL, IN, KS, MI, MN, ND, NE, SD, and WI). All isolates were screened using seed and seedling assays at two temperatures (13°C and 23°C). Seed rot and root rot severity varied by state of origin, with isolates from AR always the most aggressive. In general, isolates of P. sylvaticum and P. lutarium were more aggressive at 23°C compared with 13°C, while isolates of P. oopapillum and P. torulosum were more aggressive at 13°C than at 23°C. Fungicide sensitivity to five fungicides (metalaxyl, azoxystrobin, ethaboxam, captan, and thiram) was assessed using a plate assay at 13°C and 23°C. The EC50 values for each fungicide-isolate combination varied by state of origin, and were greatest for the isolates from AR. Temperature affected EC50 values for metalaxyl, azoxystrobin, and ethaboxam for P. oopapillum, P. sylvaticum, and P torulosum. The EC50 values for thiram were not affected by temperature for any species. Results from this study indicate that aggressiveness and fungicide sensitivity of Pythium spp. vary geographically, which suggests that management of damping-off of soybean should target local rather than regional Pythium populations.

description: Parton distributions in impact parameter space, which are obtained by Fourier transforming GPDs, exhibit a significant deviation from axial symmetry when the target and/or quark are transversely polarized. Connections between this deformation and transverse single-spin asymmetries as well as with quark-gluon correlations are discussed. The sign of transverse deformation of impact parameter dependent parton distributions in a transversely polarized target can be related to the sign of the contribution from that quark flavor to the nucleon anomalous magnetic moment. Therefore, the signs of the Sivers function for $u$ and $d$ quarks, as well as the signs of quark-gluon correlations embodied in the polarized structure function $g_2$ can be understood in terms of the proton and neutron anomalous magnetic moments.

description: We theoretically investigated the dephasing in an Aharonov-Bohm interferometer containing a lateral double quantum dot induced by coupling with a quantum dot charge sensor. We employed the interpolative 2nd-order perturbation theory to include the charge sensing Coulomb interaction. It is shown that the visibility of the Aharonov-Bohm oscillation of the linear conductance decreases monotonically as the sensing Coulomb interaction increases. In particular, for a weak sensing interaction regime, the visibility decreases parabolically, and it behaves linearly for a strong sensing interaction regime.

description: We present a general principle for estimating a regression function nonparametrically, allowing for a wide variety of data filtering, for example, repeated left truncation and right censoring. Both the mean and the median regression cases are considered. The method works by first estimating the conditional hazard function or conditional survivor function and then integrating. We also investigate improved methods that take account of model structure such as independent errors and show that such methods can improve performance when the model structure is true. We establish the pointwise asymptotic normality of our estimators.

The Kulleet Bay mass grave

Publisher: name: University of British Columbia
Year: 2019

description: This bioarchaeological study was undertaken in partnership with Stz’uminus First Nation and draws on forensic and osteological methodologies for the analysis of 153,386 cremated human bones found buried together in a mass grave. Archaeological context is integrated with the bioarchaeological results to understand the various dimensions of a mass cremation grave discovered during 2004 sewer line excavations in the traditional ancient Stz’uminus village of Kulleet Bay. Analyses of the thermally altered skeletal bone indicate fleshed bodies were intensely cremated with sustained temperatures. Vertical gradation of temperature altered matrices were observed in the stratigraphic profile. Archaeological and osteological evidence point to an in situ cremation event of fleshed corpses who suffered a mass death, radiocarbon dated to 2407 cal BP. Skeletal pathologies consistent with poor health and also potentially related to disease processes are perhaps indirect evidence of the agent of mass death. No evidence of conflict or natural environmental disaster is present to support alternative causes. This mass death event correlates precisely to the transition from Locarno to Marpole Phases ca. 2400 BP. Radiocarbon dated wood samples and a lack of artifacts dating from 2400 BP to the post contact period support a period of abandonment following the cremation event, when trees re-established in this locality within the village. Corpse treatment and mortuary processes related to the grave construction highlight social dimensions of the survivors’ attitudes, who possibly viewed the dead not as enemies or ‘foe’ but as contaminated, resulting in a mortuary treatment outside the norm of traditional Coast Salish funerary practice.

description: Wasabi (Wasabia japonica (Miq.) Matsum) plants are grown over a period of 12–18 months for their valuable rhizomes, and pathogens infecting the rhizome are of economic importance for producers. During 2016 and 2017, symptoms of wilting and internal vascular blackening of rhizomes were observed in two greenhouses in British Columbia, with disease incidence in the range of 5–10%. Isolates recovered from diseased tissues were examined morphologically and a majority (70%) resembled a Verticillium species. Molecular analysis using PCR of the ITS1-ITS2 region of rDNA and a portion of the actin gene identified the isolates as V. isaacii Inderb. R.M. Bostock, R.M. Davis & Subbarao. The optimal temperature for growth of V. isaacii on potato dextrose agar was 20°C and a distinct yellow pigment was produced, which is characteristic of species in the clade Flavexudans. Inoculation of detached wounded wasabi tissues with V. isaacii produced blackening symptoms and chlorosis on leaves. Black streaks developed on petioles and internal blackening of rhizomes was also observed. Plants inoculated in the greenhouse by immersing wounded roots in a spore suspension of V. isaacii developed a reduced root system compared with control plants. Blackening of the rhizome tissue was observed after three months. Differences were observed in pathogenicity between V. isaacii isolates. We demonstrate for the first time that V. isaacii is the cause of wilting and vascular blackening on wasabi plants. It is considered a weak pathogen, only affecting wounded tissues with symptoms developing after an extended time following inoculation.

description: In this paper, we first rework B. Kaufman's 1949 paper, "Crystal Statistics. II. Partition Function Evaluated by Spinor Analysis", by using representation theory. Our approach leads to a simpler and more direct way of deriving the spectrum of the transfer matrix for the finite periodic Ising model. We then determine formulas for the spin correlation functions that depend on the matrix elements of the induced rotation associated with the spin operator in a basis of eigenvectors for the transfer matrix. The representation of the spin matrix elements is obtained by considering the spin operator as an intertwining map. We exhibit the "new" elements V+ and V- in the Bugrij-Lisovyy formula as part of a holomorphic factorization of the periodic and anti-periodic summability kernels on the spectral curve associated with the induced rotation for the transfer matrix.

description: Botrytis blight is an economically important disease of lowbush blueberry that causes significant yield loss annually. In this study, the biofungicides, Diplomat 5SC; (polyoxin D), Timorex Gold; (tea tree oil), Fracture; (BLAD) and Serenade MAX; (Bacillus subtilis) were evaluated for their disease suppression potential against B. cinerea individually and in rotation with Switch® (cyprodinil and fludioxonil) under field conditions. Three applications of each biofungicide were made for the stand-alone treatments at 7–10 day intervals, with Switch® replacing the biofungicides during the second applications in the combined treatment. Results indicated that the products have the potential for use as a biofungicide in lowbush blueberries. All the stand-alone and rotational applications brought about a significant reduction in disease development, especially in 2019. The application of Diplomat 5SC; and Fracture®-Switch® rotation decreased disease development by over 63% in 2018. In 2019, all stand-alone treatments reduced disease development by more than 42%, whereas their rotation with Switch® reduced disease by over 69% at one site and at least 30% at another site. Stand-alone Diplomat 5SC® and Timorex Gold® along with Fracture®, Timorex Gold® and Serenade MAX; rotation resulted in over 20% more berries. This study suggests that the biofungicides and their integration with chemical fungicides have the potential as an alternative management strategy against Botrytis blossom blight to reduce the use of conventional fungicides and produce fruit with no detectable fungicide residues.

description: Under cool and wet conditions, high levels of botrytis grey mould (BGM) can occur on lentil in western Canada. Identification of local Botrytis isolates from lentil based on conidial morphology (N = 74) and sequence analysis (N = 5) indicated that B. cinerea was the predominant cause of BGM in this region. Eight field experiments at two sites (Saskatoon, SK and Outlook, SK) over two seasons were conducted to evaluate the optimal timing of the fungicide boscalid for the control of BGM in the lentil cultivar ‘CDC Grandora’. Weather conditions limited disease development in one year, but moderate levels were observed in four experiments in the other year. In all experiments, a single application at mid-flower in early-seeded experiments and at early flower in late-seeded experiments was as efficacious as a double or triple application of boscalid. There were no differences among double application treatments, and at Outlook they were all as efficacious in lowering BGM as the triple application. Despite some differences in BGM severity among fungicide applications, none of the treatments had an effect on yield or seed infection, and there was no correlation between petal colonization by B. cinerea and BGM disease severity under the study conditions.

description: Starting from the symplectic construction of the Lie algebra e_7(7) due to Adams, we consider an Iwasawa parametrization of the coset E_7(7)/SU(8), which is the scalar manifold of N=8, d=4 supergravity. Our approach, and the manifest off-shell symmetry of the resulting symplectic frame, is determined by a non-compact Cartan subalgebra of the maximal subgroup SL(8,R) of E_7(7). In absence of gauging, we utilize the explicit expression of the Lie algebra to study the origin of E_7(7)/SU(8) as scalar configuration of a 1/8-BPS extremal black hole attractor. In such a framework, we highlight the action of a U(1) symmetry spanning the dyonic 1/8-BPS attractors. Within a suitable supersymmetry truncation allowing for the embedding of the Reissner-Nordstrom black hole, this U(1) is interpreted as nothing but the global R-symmetry of pure N=2 supergravity. Moreover, we find that the above mentioned U(1) symmetry is broken down to a discrete subgroup Z_4, implying that all 1/8-BPS Iwasawa attractors are non-dyonic near the origin of the scalar manifold. We can trace this phenomenon back to the fact that the Cartan subalgebra of SL(8,R) used in our construction endows the symplectic frame with a manifest off-shell covariance which is smaller than SL(8,R) itself. Thus, the consistence of the Adams-Iwasawa symplectic basis with the action of the U(1) symmetry gives rise to the observed Z_4 residual non-dyonic symmetry.

description: Mycosphaerella blight, caused by Peyronellaea pinodes (Berk. & A. Bloxam) Aveskamp, Gruyter & Verkley (syn. Mycosphaerella pinodes (Berk. et Blox.) Vesterg.), is a destructive foliar pathogen of field pea that is managed, in large part, through application of foliar fungicide at flowering. The fungicides are usually applied into dense crop canopies, so reaching the lower areas of the canopy where the pathogen is initially most active is a challenge. Field trials were conducted across the Canadian prairies from 2008 to 2011 to assess the efficacy of various nozzle numbers and orientations, droplet sizes, and water volumes for the management of Mycosphaerella blight to increase yield in field pea. Pea plants were assessed for disease severity during flowering and seed yield was measured. In 10 of the 13 trials, double-nozzle configurations provided a 15% reduction in disease severity and up to a 60% increase in yield. In contrast, droplet size and angle of application had no effect on field pea yield. Water volume trials using up to 400 L ha−1 improved fungicide efficacy relative to control treatments, however, volumes above 400 L ha−1 resulted in high-disease severity and lower yield, likely as a result of fungicide run-off due to saturation of the leaf surface. When deciding on effective sprayer techniques for fungicide application, disease pressure, environmental conditions and cultivar characteristics are important to consider.

Our results confirm the predictions based on the Luttinger liquid and conformal field theory approaches. We also demonstrate that the amplitudes arising in this asymptotic expansion at low-temperature coincide with the amplitudes associated with the so-called critical form factors.

description: At this moment in time, I would - in normal circumstances - be studying in my Oxford dorm. This morning is different. I have woken up at 5:30 to make my way to the Covid-19 Testing Centre in my town to begin working. It's raining heavily but we're continuing to provide an essential service - helping the sick and vulnerable to test themselves safely. It's long hours and hard work but I'm glad to be doing my part in the fight against this terrible virus, which is affecting each and every one of us in some area of our lives. I miss my studies and friends, but I'm determined to stay positive and I get a great deal of satisfaction from my work - I meet and work with people from all walks of life, and this only underlines how indiscriminate Covid can be, and the joys of how we can all be brought together in crisis.
It's a surreal environment to work in. Cars snake into the centre from 8am, seven days a week. We are only able to communicate through the car windows, which is often an exercise in itself. Confusion and communication difficulties abound. They make their way from station to station, greeted by masked workers, and take their tests. Many are incredibly anxious. It's a stressful time for all involved, and you can't help but feel tremendous sympathy for those whose health won't stand a positive result.
Yet this is also an incredibly uplifting place to work. There are regular laughs, and the camaraderie amongst the staff keeps me hopeful of a time when the centre will no longer be needed, and we may all be happily made redundant and return to our normal lives.

description: We show experimentally and theoretically that the spectral components of a multi-octave frequency comb spontaneously created by stimulated Raman scattering in a hydrogen-filled hollow-core photonic crystal fiber exhibit strong self coherence and mutual coherence within each 12 ns driving laser pulse. This coherence arises in spite of the field's initiation being from quantum zero-point fluctuations, which causes each spectral component to show large phase and energy fluctuations. This points to the possibility of an optical frequency comb with nonclassical correlations between all comb lines.

Dynamic dissolution and inhibition of biofilm development by endodontic disinfecting agents

Publisher: name: University of British Columbia

description: Many disinfecting solutions have been developed to disrupt the biofilm and to kill biofilm bacteria. However, there is little data so far showing dynamic dissolution on biofilm. The present study aims to establish a standardized model that makes it possible to evaluate the dynamic dissolution of biofilm and inhibition of growth of multispecies biofilm by endodontic irrigation solutions. Biofilm was grown from plaque bacteria on collagen coated hydroxyapatite (HA) disks in brain-heart infusion broth for 3 days or 3 weeks under anaerobic conditions. Biofilms were stained by the LIVE/DEAD viability stain and subjected to sterile water, 2% sodium hypochlorite (NaOCl), 6% NaOCl, or 2% chlorhexidine (CHX) for 32 minutes. Dynamic change in fluorescence from each biofilm sample after treatment was analyzed using a live-cell imaging confocal laser scanning microscopy (LC-CLSM). Biovolume and proportion of dead bacteria were calculated. The biofilm structures after treatments were visualized by scanning electron microscopy (SEM). The treated biofilms on HA disks were collected and cultured on blood agar plates for the colony forming unit (CFU) test. Another set of sterile HA disks were immersed in 2%, 0.2% or 0.02% CHX solutions for 3 minutes. Plaque biofilm growth on these disks was monitored by LC-CLSM for 12 hours. For 3-day-old biofilms, 2% and 6% NaOCl reduced the biovolume by 63% and 94% in 32 minutes respectively. For 3-week-old biofilms, 75% and 86% of the biofilm was dissolved by 2% and 6% NaOCl respectively in 32 minutes. Six percent NaOCl was the most effective in dissolving and killing bacteria followed by 2% NaOCl and CHX. CFU results indicated difference in bacterial reduction between biofilm and planktonic culturing after disinfection. SEM showed biofilm bacteria disruption after CHX and NaOCl treatments. The use of 2% CHX and sterile water did not result in biofilm dissolution. However, prior exposure of HA disks to 2% and 0.2% CHX for 3 minutes prevented biofilm from growing on HA disk surfaces for at least 12 hours. In conclusion, NaOCl dissolved biofilm effectively, more with higher concentration and longer time of exposure. CHX does not dissolve biofilm but inhibits biofilm growth on HA surface.

description: Interaction between consumers and companies can create conflict. When a consensus is unreachable there are legal authorities to resolve the case. This letter is a study of data from the Brazilian Department of Justice from which we build a bipartite network of categories of complaints linked to the companies receiving those complaints. We find the complaint categories organised in an hierarchical way where companies only get complaints of lower degree if they already got complaints of higher degree. The fraction of resolved complaints for a company appears to be nearly independent on the equity of the company but is positively correlated with the total number of complaints received. We construct feature vectors based on the edge-weight - the weight of an edge represents the times complaints of a category have been filed against that company - and use these vectors to study the similarity between the categories of complaints. From this analysis, we obtain trees mapping the hierarchical organisation of the complaints. We also apply principal component analysis to the set of feature vectors concluding that a reduction of the dimensionality of these from 8827 to 27 gives an optimal hierarchical representation.

description: We examine the relation between black hole accretion and bulge star formation as a function of look-back time (tau) in 20,541 obscured AGNs (with redshifts ~ 0.1 and bolometric luminosities L_Bol ~ 10^43--10^45 erg s^-1) optically selected from the Sloan Digital Sky Survey (SDSS). To quantify the most recently formed stars with ages less than typical AGN lifetimes, we estimate the differentiated specific star formation rate (SSFR_tau) based on population synthesis analysis. Eddington ratio (lambda) is inferred using [O III]5007 luminosity and stellar velocity dispersion as proxies for L_Bol and black hole mass respectively. We find that when tau < tau_0, SDSS AGNs follow a power law: lambda \propto (SSFR_tau)^1.0-1.1; the relation flattens out when tau > tau_0. The threshold timescale tau_0 is ~ 0.1 (~ 1) Gyr in young (old) bulges. The scatter in the power laws is dominated by observational uncertainties. These results may provide useful constraints on models explaining the correlations between AGN activity and bulge star formation.

description: Mycosphaerella blight, caused by Peyronellaea pinodes (Berk. & A. Bloxam) Aveskamp, Gruyter & Verkley (syn. Mycosphaerella pinodes (Berk. et Blox.) Vesterg.), is a destructive foliar pathogen of field pea that is managed, in large part, through application of foliar fungicide at flowering. The fungicides are usually applied into dense crop canopies, so reaching the lower areas of the canopy where the pathogen is initially most active is a challenge. Field trials were conducted across the Canadian prairies from 2008–2011 to assess the efficacy of various nozzle numbers and orientations, droplet sizes, and water volumes for the management of Mycosphaerella blight to increase yield in field pea. Pea plants were assessed for disease severity during flowering and seed yield was measured. In 10 of the 13 trials, double-nozzle configurations provided a 15 % reduction in disease severity and up to a 60 % increase in yield. In contrast, droplet size and angle of application had no effect on field pea yield. Water volume trials using up to 400 L ha−1 improved fungicide efficacy relative to control treatments, however, volumes above 400 L ha−1 resulted in high disease severity and lower yield, likely as a result of fungicide run-off due to saturation of the leaf surface. When deciding on effective sprayer techniques for fungicide application, disease pressure, environmental conditions and cultivar characteristics are important to consider.

description: The phosphonothioamidates (EtO)2P(=O)C(=S)N(H)R (L1 R = Cy; L2 R = Bz) have been prepared by nucleophilic addition of K[(EtO)2P(=O)] to R–N = C=S and crystallographically analyzed. Both compounds are associated pairwise through strong intermolecular N–H···O bonding giving rise to 10-membered supramolecular macrocycles. This intermolecular bonding has also been studied by Hirshfeld analysis of L1 and L2. Complexation of L on CuI in MeCN solution affords the dinuclear rhomboid-shaped thione complexes [{Cu(μ2-I)2Cu}(η1-L)2] (1a,b). Crystallographic characterization of 1a reveals that L1 is ligated exclusively via the thione function to the trigonal Cu(I) centers, which are interconnected through a short Cu–Cu bond of 2.6207(4) Å. In the solid state, individual dimeric complexes are associated through intermolecular N–H···O bonding generating a supramolecular 1D ribbon. The dinuclear complexes [{XHg(μ2-X)2HgX}(η1-L)2] (2a X = Br, L = Cy; 2b X = Br, L = Bz; 2c X = I, L = Bz) were formed by stoichiometric addition of L to HgX2. The molecular structures of 2b and 2c have been elucidated by X-ray diffraction studies, which show that individual complexes are connected through intermolecular N–H···O bonding generating a supramolecular 1D ribbon. Treatment of L1 with two equivalents of HgBr2 produces the tetranuclear compound [Hg4Br8(κ1-L1)2] 3, whose unusual bromide-bridged architecture has been elucidated by X-ray crystallography.

description: Uncertainty in economics still poses some fundamental problems illustrated, e.g., by the Allais and Ellsberg paradoxes. To overcome these difficulties, economists have introduced an interesting distinction between 'risk' and 'ambiguity' depending on the existence of a (classical Kolmogorovian) probabilistic structure modeling these uncertainty situations. On the other hand, evidence of everyday life suggests that 'context' plays a fundamental role in human decisions under uncertainty. Moreover, it is well known from physics that any probabilistic structure modeling contextual interactions between entities structurally needs a non-Kolmogorovian quantum-like framework. In this paper we introduce the notion of 'contextual risk' with the aim of modeling a substantial part of the situations in which usually only 'ambiguity' is present. More precisely, we firstly introduce the essentials of an operational formalism called 'the hidden measurement approach' in which probability is introduced as a consequence of fluctuations in the interaction between entities and contexts. Within the hidden measurement approach we propose a 'sphere model' as a mathematical tool for situations in which contextual risk occurs. We show that a probabilistic model of this kind is necessarily non-Kolmogorovian, hence it requires either the formalism of quantum mechanics or a generalization of it. This insight is relevant, for it explains the presence of quantum or, better, quantum-like, structures in economics, as suggested by some authors, and can serve to solve the aforementioned paradoxes.

description: As part of the NASA EPOXI Mission of Opportunity, we observed seven known transiting extrasolar planet systems in order to construct time series photometry of extremely high phase coverage and precision. Here we present the results for four "hot-Jupiter systems" with near-solar stars - HAT-P-4, TrES-3, TrES-2 and WASP-3. We observe ten transits of HAT-P-4, estimating the planet radius Rp = 1.332 \pm 0.052 RJup, the stellar radius R \star = 1.602 \pm 0.061 R \odot, the inclination i = 89.67 \pm 0.30 degrees and the transit duration from first to fourth contact T = 255.6 \pm 1.9 minutes. For TrES-3, we observe seven transits, and find Rp = 1.320 \pm 0.057 RJup, R\star = 0.817 \pm 0.022 R\odot, i = 81.99 \pm 0.30 degrees and T = 81.9 \pm 1.1 minutes. We also note a long term variability in the TrES-3 light curve, which may be due to star spots. We observe nine transits of TrES-2, and find Rp = 1.169 \pm 0.034 RJup, R\star = 0.940 \pm 0.026 R\odot, i = 84.15 \pm 0.16 degrees and T = 107.3 \pm 1.1 minutes. Finally we observe eight transits of WASP-3, finding Rp = 1.385 \pm 0.060 RJup, R\star = 1.354 \pm 0.056 R\odot, i = 84.22 \pm 0.81 degrees and T = 167.3 \pm 1.3 minutes. We present refined orbital periods and times of transit for each target. We state 95% confidence upper limits on the secondary eclipse depths in our broadband visible bandpass centered on 650 nm. These limits are 0.073% for HAT-P-4, 0.062% for TrES-3, 0.16% for TrES-2 and 0.11% for WASP-3. We combine the TrES-3 secondary eclipse information with the existing published data and confirm that the atmosphere likely does not have a temperature inversion.

description: A discrepancy has emerged between the cosmic lithium abundance inferred by the WMAP satellite measurement coupled with the prediction of the standard big-bang nucleosynthesis theory, and the constant Li abundance measured in metal-poor halo dwarf stars (the so-called Spite plateau). Several models are being proposed to explain this discrepancy, involving either new physics, in situ depletion, or the efficient depletion of Li in the pristine Galaxy by a generation of massive first stars. The realm of possibilities may be narrowed considerably by observing stellar populations in different galaxies, which have experienced different evolutionary histories. The WCen stellar system is commonly considered as the remnant of a dwarf galaxy accreted by the Milky Way (MW). We investigate the Li content of a conspicuous sample of unevolved stars in this object. We obtained moderate resolution (R=17000) spectra for 91 main-sequence/early sub-giant branch (MS/SGB) WCen stars using the FLAMES-GIRAFFE/VLT spectrograph. Li abundances were derived by matching the equivalent width of the LiI resonance doublet at 6708A, to the prediction of synthetic spectra computed with different Li abundances. Synthetic spectra were computed using the SYNTHE code along with ATLAS9 model atmospheres. The stars effective temperatures are derived by fitting the wings of the Ha line with synthetic profiles. We obtain a mean content of A(Li)=2.19+-0.14~dex for WCen MS/SGB stars. This is comparable to what is observed in Galactic halo field stars of similar metallicities and temperatures. The Spite plateau seems to be an ubiquitous feature of old, warm metal-poor stars. It exists also in external galaxies, if we accept the current view about the origin of WCen. This implies that the mechanism(s) that causes the "cosmological lithium problem" may be the same in the MW and other galaxies.

A mitochondrial terminomics technique to study human cell death during bacterial infection

description: Mitochondria are essential for human health. While mitochondria are primarily known for their essential role in generating cellular energy, these organelles play many vital roles in eukaryotic cells, including the cellular stress response, innate immunity, and the regulation of intrinsic apoptosis. Mitochondrial proteases are essential for mitochondrial function, including the import of 99% of the mitochondrial proteome, which often requires the proteolytic removal of a mitochondrial targeting sequence (MTS), creating a new protein amino terminus. However, little is known about how proteases regulate mitochondrial functions during health and disease because of the lack of tools able to examine global mitochondrial proteolysis and how it changes during mitochondrial processes. A novel terminomics workflow called ‘MS-TAILS’ was developed to address this gap by identifying changes in the mitochondrial terminal proteome, reflective of mitochondrial proteome-wide proteolysis. MS-TAILS identified the highest coverage of the human mitochondrial proteome and the most sites of import-associated MTS removal of any terminomics study to date, as well as 97 novel sites of mitochondrial proteolysis, demonstrating its utility to study mitochondrial proteolysis, proteases, and proteome import. MS-TAILS was applied to characterize mitochondrial changes during the induction of intrinsic apoptosis: a critical but poorly characterized mitochondrial process. MS-TAILS identified apoptosis-dependent changes in seven mitochondrial proteins not previously implicated in apoptosis, which may indicate conserved early apoptotic events. We examined the role of mitochondrial proteases in innate immunity by conducting the first terminomics study of microbial infection, identifying infection-specific mitochondrial changes during enteropathogenic E.coli (EPEC) infection: a pathogen that uses a type III secretion system (T3SS) to inject effectors into human cells and mitochondria to modulate apoptosis and immunity. The majority of infection- and T3SS effector-dependent mitochondrial changes were unique from canonical apoptosis events, suggesting that EPEC T3SS effectors mediate an infection-associated mitochondrial apoptosis pathway. These findings were examined in a broader context to demonstrate the impact of this thesis work on the field. Overall, this work provides a novel approach to study global dynamics in mitochondrial proteolysis between conditions and therefore addresses a technical gap to characterize mitochondrial proteases, processes, and pathologies, including and beyond apoptosis.
