description: The capacity and cost-per-bit of DRAM have historically scaled to satisfy the needs of increasingly large and complex computer systems. However, DRAM latency has remained almost constant, making memory latency the performance bottleneck in today's systems. We observe that the high accesslatency is not intrinsic to DRAM, but a trade-off made to decrease cost-per-bit. To mitigate the high area overhead of DRAM sensing structures, commodity DRAMs connect many DRAM cells to each sense-amplifier through a wire called a bitline. These bitlines have a high parasitic capacitance due to their long length, and this bitline capacitance is the dominant source of DRAM latency. Specialized low-latency DRAMs use shorter bitlines with fewer cells, but have a higher cost-per-bit due to greater sense-amplifier area overhead. In this work, we introduce Tiered-Latency DRAM (TL-DRAM), which achieves both low latency and low cost-per-bit. In TL-DRAM, each long bitline is split into two shorter segments by an isolation transistor, allowing one segment to be accessed with the latency of a short-bitline DRAM without incurring high cost-per-bit. We propose mechanisms that use the low-latencysegment as a hardware-managed or software-managed cache. Evaluations show that our proposed mechanisms improve both performance and energy-efficiency for both single-core and multi-programmed workloads.
The Very Low Albedo of WASP-12b From Spectral Eclipse Observations with $\textit{Hubble}$

description: We present an optical eclipse observation of the hot Jupiter WASP-12b using the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope. These spectra allow us to place an upper limit of $A_g < 0.064$ (97.5% confidence level) on the planet's white light geometric albedo across 290--570 nm. Using six wavelength bins across the same wavelength range also produces stringent limits on the geometric albedo for all bins. However, our uncertainties in eclipse depth are $\sim$40% greater than the Poisson limit and may be limited by the intrinsic variability of the Sun-like host star --- the solar luminosity is known to vary at the $10^{-4}$ level on a timescale of minutes. We use our eclipse depth limits to test two previously suggested atmospheric models for this planet: Mie scattering from an aluminum-oxide haze or cloud-free Rayleigh scattering. Our stringent nondetection rules out both models and is consistent with thermal emission plus weak Rayleigh scattering from atomic hydrogen and helium. Our results are in stark contrast with those for the much cooler HD 189733b, the only other hot Jupiter with spectrally resolved reflected light observations; those data showed an increase in albedo with decreasing wavelength. The fact that the first two exoplanets with optical albedo spectra exhibit significant differences demonstrates the importance of spectrally resolved reflected light observations and highlights the great diversity among hot Jupiters.

The role of symmetries in the vanishing of the first order correction is manifest in our calculation.

description: A recurring problem in security is reverse engineering binary code to recover high-level language data abstractions and types. High-level programming languages have data abstractions such as buffers, structures, and local variables that all help programmers and program analyses reason about programs in a scalable manner. During compilation, these abstractions are removed as code is translated down to operations on registers and one globally addressed memory region. Reverse engineering consists of “undoing” the compilation to recover high-level information so that programmers, security professionals, and analyses can all more easily reason about the binary code. In this paper we develop novel techniques for reverse engineering data type abstractions from binary programs. At the heart of our approach is a novel type reconstruction system based upon binary code analysis. Our techniques and system can be applied as part of both static or dynamic analysis, thus are extensible to a large number of security settings. Our results on 87 programs show that TIE is both more accurate and more precise at recovering high-level types than existing mechanisms.

description: We continue the study of a local, gauge invariant Yang-Mills action containing a mass parameter, which we constructed in a previous paper starting from the nonlocal gauge invariant mass dimension two operator F_{μν} (D^2)^{-1} F_{μν}. We return briefly to the renormalizability of the model, which can be proven to all orders of perturbation theory by embedding it in a more general model with a larger symmetry content. We point out the existence of a nilpotent BRST symmetry. Although our action contains extra (anti)commuting tensor fields and coupling constants, we prove that our model in the limit of vanishing mass is equivalent with ordinary massless Yang-Mills theories. The full theory is renormalized explicitly at two loops in the MSbar scheme and all the renormalization group functions are presented. We end with some comments on the potential relevance of this gauge model for the issue of a dynamical gluon mass generation.

description: We present the strain and temperature dependence of an anomalous nematic phase in optimally doped BaFe$_2$(As,P)$_2$. Polarized ultrafast optical measurements reveal broken 4-fold rotational symmetry in a temperature range above $T_c$ in which bulk probes do not detect a phase transition. Using ultrafast microscopy, we find that the magnitude and sign of this nematicity vary on a ${50{-}100}~μ$m length scale, and the temperature at which it onsets ranges from 40 K near a domain boundary to 60 K deep within a domain. Scanning Laue microdiffraction maps of local strain at room temperature indicate that the nematic order appears most strongly in regions of weak, isotropic strain. These results indicate that nematic order arises in a genuine phase transition rather than by enhancement of local anisotropy by a strong nematic susceptibility. We interpret our results in the context of a proposed surface nematic phase.

description: We systematically analyze X-ray variability of active galactic nuclei (AGNs) in the 7~Ms \textit{Chandra} Deep Field-South survey. On the longest timescale ($\approx~17$ years), we find only weak (if any) dependence of X-ray variability amplitudes on energy bands or obscuration. We use four different power spectral density (PSD) models to fit the anti-correlation between normalized excess variance ($σ^2_{\rm nxv}$) and luminosity, and obtain a best-fit power law index $β=1.16^{+0.05}_{-0.05}$ for the low-frequency part of AGN PSD. We also divide the whole light curves into 4 epochs in order to inspect the dependence of $σ^2_{\rm nxv}$ on these timescales, finding an overall increasing trend. The analysis of these shorter light curves also infers a $β$ of $\sim 1.3$ that is consistent with the above-derived $β$, which is larger than the frequently-assumed value of $β=1$. We then investigate the evolution of $σ^2_{\rm nxv}$. No definitive conclusion is reached due to limited source statistics but, if present, the observed trend goes in the direction of decreasing AGN variability at fixed luminosity toward large redshifts. We also search for transient events and find 6 notable candidate events with our considered criteria. Two of them may be a new type of fast transient events, one of which is reported here for the first time. We therefore estimate a rate of fast outbursts $\langle\dot{N}\rangle = 1.0^{+1.1}_{-0.7}\times 10^{-3}~\rm galaxy^{-1}~yr^{-1}$ and a tidal disruption event~(TDE) rate $\langle\dot{N}_{\rm TDE}\rangle=8.6^{+8.5}_{-4.9}\times 10^{-5}~\rm galaxy^{-1}~yr^{-1}$ assuming the other four long outbursts to be TDEs.

description: Yes! Very much so. A chimera state refers to the coexistence of a coherent-incoherent dynamical evolution of identically coupled oscillators. We investigate the impact of multiplexing of a lyer having repulsively coupled oscillators on occurrence of chimeras in the layer having attractively coupled identical oscillators. We report that there exists an enhancement in the appearance of chimera state in one layer of multiplex network in the presence of repulsive coupling in the other layer. Furthermore, we show that a small amount of inhibition or repulsive coupling in one layer is sufficient to yield chimera state in another layer by destroying its synchronized behavior. These results can be used to get insight into dynamical behaviors of those systems where both attractive and repulsive coupling exist among their constituents.

description: We consider pairing in a three-component gas of degenerate fermions. In particular, we solve the finite temperature mean-field theory of an interacting gas for a system where both interaction strengths and fermion masses can be unequal. At zero temperature we find a a possibility of a quantum phase transition between states associated with pairing between different pairs of fermions. On the other hand, finite temperature behavior of the three-component system reveals some qualitative differences from the two-component gas: for a range of parameters it is possible to have two different critical temperatures. The lower one corresponds to a transition between different pairing channels, while the higher one corresponds to the usual superfluid-normal transition. We discuss how these phase transitions could be observed in ultracold gases of fermionic atoms.

description: Almost every star in our Galaxy is likely to harbor a terrestrial planet, but accurate measurements of an exoplanet's mass and radius demands accurate knowledge of the properties of its host star. The imminent TESS and CHEOPS missions are slated to discover thousands of new exoplanets. Along with WFIRST, which will directly image nearby planets, these surveys make urgent the need to better characterize stars in the nearby solar neighborhood (< 30 pc). We have compiled the CATalog of Stellar Unified Properties (CATSUP) for 951 stars, including such data as: Gaia astrometry; multiplicity within stellar systems; stellar elemental abundance measurements; standardized spectral types; Ca II H and K stellar activity indices; GALEX NUV and FUV photometry; and X-ray fluxes and luminosities from ROSAT, XMM, and Chandra. We use this data-rich catalog to find correlations, especially between stellar emission indices, colors, and galactic velocity. Additionally, we demonstrate that thick-disk stars in the sample are generally older, have lower activity, and have higher velocities normal to the galactic plane. We anticipate CATSUP will be useful in discerning other trends among stars within the nearby solar neighborhood, for comparing thin-disk vs. thick-disk stars, for comparing stars with and without planets, and for finding correlations between chemical and kinematic properties.

description: Using a group theory approach, we investigate the basic features of the Landau problem on the Bergman ball {\bf B}^k. This can be done by considering a system of particles living on {\bf B}^k in the presence of an uniform magnetic field B and realizing the ball as the coset space SU(k,1)/U(k). In quantizing the theory on {\bf{B}}^k, we define the wavefunctions as the Wigner \cal{D}-functions satisfying a set of suitable constraints. The corresponding Hamiltonian is mapped in terms of the right translation generators. In the lowest Landau level, we obtain the wavefunctions as the SU(k,1) coherent states. This are used to define the star product, density matrix and excitation potential in higher dimensions. With these ingredients, we construct a generalized effective Wess-Zumino-Witten action for the edge states and discuss their nature.

description: We present integrated-light spectra of 8 Young Massive Clusters (YMCs) in the metal-rich spiral galaxy NGC 5236 (M 83). The observations were taken with the X-Shooter spectrograph on the ESO Very Large Telescope. Through the use of theoretical isochrones and synthetic integrated-light (IL) spectra we derive metallicities and study the radial metallicity gradient observed through these young populations. For the inner regions of the galaxy we observe a relatively shallow metallicity gradient of $-$0.37 $\pm$0.29 dex R$_{25}^{-1}$, agreeing with chemical evolution models with an absence of infall material and a relatively low mass loss due to winds in the inner parts of the disk. We estimate a central metallicity of [$Z$] = $+$0.17 $\pm$ 0.12 dex, finding excellent agreement with that obtained via other methods (e.g. blue supergiants and J-band). We infer a metallicity of 12+log(O/H) = 8.75 $\pm$ 0.08 dex at R/R$_{25}$ = 0.4, which fits the stellar mass-metallicity relation (MZR) compilation of blue supergiants and IL studies.

description: Abstract: "An equation based process simulation program must address three major issues if it is to be useful to the practicing engineer: 1. The simulator must provide a graphical flowsheeting interface for convenient manipulation of equation and variables. 2. The simulator must support the user in developing a vaild problem specification, i.e., avoidance of structural singularities. 3. The simulator must recover gracefully from numerical singularities. We have developed a prototype simulator that addresses these issues. The first two capabilities have been implemented and a suggestion for the third is sketched."

description: A re-analysis of the radio continuum emission from circumnuclear regions of the barred galaxies NGC 1022, 1326 & 4314 is presented. The spatial distributions of Halpha and radio continuum are similar and suggest the existence of several giant HII regions in the circumnuclear zone. The spectral indices of the HII regions, obtained with similar angular resolution and at three different wavelengths, indicate that in all three galaxies, the spectral index, alpha^6_2 >-0.1. This result suggests the existence of giant HII regions with decreasing density gradients. The average density stratifications of these HII regions could be approximated by power-laws of the form n_e~r^-w, with exponents in the range 1.6 < w < 2.4.

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We present an approach for simulating the collisional evolution of spherical isotropic stellar systems based on the one-dimensional Fokker-Planck equation. A novel aspect is that we use the phase volume as the argument of the distribution function, instead of the traditionally used energy, which facilitates the solution. The publicly available code, PhaseFlow, implements a high-accuracy finite-element method for the Fokker-Planck equation, and can handle multiple-component systems, optionally with the central black hole and taking into account loss-cone effects and star formation. We discuss the energy balance in the general setting, and in application to the Bahcall-Wolf cusp around a central black hole, for which we derive a perturbative solution. We stress that the cusp is not a steady-state structure, but rather evolves in amplitude while retaining an approximately $ρ\propto r^{-7/4}$ density profile. Finally, we apply the method to the nuclear star cluster of the Milky Way, and illustrate a possible evolutionary scenario in which a two-component system of lighter main-sequence stars and stellar-mass black holes develops a Bahcall-Wolf cusp in the heavier component and a weaker $ρ\propto r^{-3/2}$ cusp in the lighter, visible component, over the period of several Gyr. The present-day density profile is consistent with the recently detected mild cusp inside the central parsec, and is weakly sensitive to initial conditions.

description: An 8000-unit dairy replacement calf ranch experienced high morbidity and mortality related to exposure of calves to aflatoxin M1 isolated in the milk replacer [place and date not given]. During the six-week exposure period, pre-weaning calf morbidity was 100%, and approximately 3000 calves died. Aflatoxin M1 is an intermediate metabolite of aflatoxin B1, and is found in milk of dairy cows consuming a contaminated ration. Histopathology demonstrated changes in the centrilobular hepatocytes as well as the biliary tree. Serum chemistry values indicated an ongoing liver disorder. Toxicologic evaluation of the milk replacer revealed the presence of aflatoxin M1. Within three days of removal of the affected milk replacer, morbidity and mortality levels returned to baseline levels for this ranch.

description: Phase transitions occupy a central role in physics, due both to their experimental ubiquity and their fundamental conceptual importance. The explanation of universality at phase transitions was the great success of the theory formulated by Ginzburg and Landau, and extended through the renormalization group by Wilson. However, recent theoretical suggestions have challenged this point of view in certain situations. In this Letter we report the first large-scale simulations of a three-dimensional model proposed to be a candidate for requiring a description beyond the Landau-Ginzburg-Wilson framework: we study the phase transition from the dimer crystal to the Coulomb phase in the cubic dimer model. Our numerical results strongly indicate that the transition is continuous and are compatible with a tricritical universality class, at variance with previous proposals.

description: Serum neutralizing (SN) antibody titres to cytopathic (cp) type 1a, type 1b and type 2 bovine viral diarrhoea viruses (BVDV) were determined for yearling, crossbred beef heifers immunized with a modified live cytopathic type 1a BVDV vaccine, or experimentally infected with a noncytopathic (ncp) type 1b or a ncp type 2 BVDV. The results indicate that type-specific and cross-reactive SN titres are usually found to all three test viruses in an individual animal, with the highest SN titres to the same genotype of BVDV as the challenge or vaccine virus. Exceptions to this trend were found in individual animals, however, emphasizing the importance of comparing the SN titres for several animals in a herd. Determining SN titres to the three BVDV genotypes may help veterinarians distinguish the BVDV genotype involved in a herd infection from antibody titres due to vaccination.

description: In a modern chip-multiprocessor system, memory is a shared resource among multiple concurrently executing threads. The memory scheduling algorithm should resolve memory contention by arbitrating memory access in such a way that competing threads progress at a relatively fast and even pace, resulting in high system throughput and fairness. Previously proposed memory scheduling algorithms are predominantly optimized for only one of these objectives: no scheduling algorithm provides the best system throughput and best fairness at the same time. This paper presents a new memory scheduling algorithm that addresses system throughput and fairness separately with the goal of achieving the best of both. The main idea is to divide threads into two separate clusters and employ different memory request scheduling policies in each cluster. Our proposal, Thread Cluster Memory scheduling (TCM), dynamically groups threads with similar memory access behavior into either the latency-sensitive (memory-non-intensive) or the bandwidth-sensitive (memory-intensive) cluster. TCM introduces three major ideas for prioritization: 1) we prioritize the latency-sensitive cluster over the bandwidth-sensitive cluster to improve system throughput, 2) we introduce a ``niceness'' metric that captures a thread's propensity to interfere with other threads, 3) we use niceness to periodically shuffle the priority order of the threads in the bandwidth-sensitive cluster to provide fair access to each thread in a way that reduces inter-thread interference. On the one hand, prioritizing memory-non-intensive threads significantly improves system throughput without degrading fairness, because such ``light'' threads only use a small fraction of the total available memory bandwidth. On the other hand, shuffling the priority order of memory-intensive threads improves fairness because it ensures no thread is disproportionately slowed down or starved. We evaluate TCM on a wide variety of multiprogrammed worklo- - ads and compare its performance to four previously proposed scheduling algorithms, finding that TCM achieves both the best system throughput and fairness. Averaged over 96 workloads on a 24-core system with 4 memory channels, TCM improves system throughput and reduces maximum slowdown by 4.6%/38.6% compared to ATLAS (previous work providing the best system throughput) and 7.6%/4.6% compared to PAR-BS (previous work providing the best fairness).

description: The purpose of this study was to compare the antibody responses of cattle vaccinated with one of five commercial non-living P. haemolytica vaccines during the first two weeks after a single vaccination. Antibodies to surface antigens (whole cells) and to the leukotoxin (LKT) were quantified at Days 7 and 14 after vaccination. In addition, antibodies to specific P. haemolytica whole cell protein antigens were determined by immunoblots using sera from vaccinated and control calves. Three hundred pre-weaned, mixed beef breed steers and heifers, greater than three months old, were equally divided among five vaccinated and one placebo groups. Cattle were subcutaneously injected with one of the following commercial P. haemolytica vaccines: One Shot, One Shot Ultra 8, Pyramid 4+Presponse SQ, Pulmo-guard PH-M or Poly-Bac B 1. Antibody responses to both LKT and whole cells were highest on Day 7 for One Shot and One Shot Ultra. By Day 14, Pulmo-Guard stimulated serum antibodies to both antigen preparations that were equivalent to those for One Shot and One Shot Ultra. Serum antibodies to LKT and whole cells were detected in the Pyramid/Presponse- and Poly-Bac 1 - vaccinated groups; however, those responses were not significantly different from the placebo group. Each vaccine, except for the Pyramid 4/Presponse - vaccinated group, stimulated antibodies to similar P. haemolytica somatic proteins, particularly at 200, 100, 60-70, 45, 35 and 25 kDa. Sera from the Pyramid 4/Presponse-vaccinated group recognized fewer protein bands, mainly those at 200, 70-75, 48 and 35 kDa. In conclusion, various commercial vaccines induced differences in the rapidity and the intensity of serum antibody responses to P. haemolytica whole cells and LKT.

Mycoplasma infection in cattle. I, Pneumonia-arthritis syndrome

description: Mycoplasma spp. are unique microorganisms associated with several disease entities, including a pneumonia- arthritis syndrome in cattle. One of the challenges in determining the role of Mycoplasma spp. in bovine disease is that this organism has been isolated from both normal and diseased animals. When dealing with field cases of mycoplasma pneumonia, it is common to find mixed infections. Additionally, observations from research studies and clinical experience have indicated that the presence of mycoplasma increases the severity of respiratory disease. There are no pathognomonic signs for mycoplasma infections. Clinical signs associated with respiratory infections include tachypnea, dyspnea, ocular and nasal discharge, depression, decreased appetite, arched stance and fever. Clinical signs associated with joint infections include stiffness, lameness, difficulty when rising, swollen joints and tendon sheaths, decreased appetite and weight loss. The organism requires special growth media and conditions to be cultured in the laboratory. If a practitioner wants to confirm a diagnosis with a positive culture, he/she must specifically request a mycoplasma culture when samples are submitted to the laboratory. Besides determining the significance of Mycoplasma spp. in disease, the practitioner is faced with recommending appropriate and effective treatments. Response to therapy, both experimentally and under field conditions, is variable and frequently unrewarding. Since mycoplasma organisms are resistant to several therapies, sound biosecurity and biocontainment programs that minimize stress and exposure to the organism are the best recommendations that practitioners can discuss with producers for prevention and control.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Extremely metal-poor (EMP) stars are the living fossils with records of chemical enrichment history at the early epoch of galaxy formation. By the recent large observation campaigns, statistical samples of EMP stars have been obtained. This motivates us to reconsider their classification and formation conditions. From the observed lower-limits of carbon and iron abundances of Acr(C) ~ 6 and [Fe/H]cr ~ -5 for C-enhanced EMP (CE-EMP) and C-normal EMP (CN-EMP) stars, we confirm that gas cooling by dust thermal emission is indispensable for the fragmentation of their parent clouds to form such low-mass, i.e., long-lived stars, and that the dominant grain species are carbon and silicate, respectively. We constrain the grain radius r_i^{cool} of a species i and condensation efficiency f_{ij} of a key element j as r_C^{cool}/f_{C, C} = 10 um and r_Sil^{cool}/f_{Sil, Mg} = 0.1 um to reproduce Acr(C) and [Fe/H]cr, which give a universal condition 10^{[C/H]-2.30} + 10^[Fe/H] > 10^{-5.07} for the formation of every EMP star. Instead of the conventional boundary [C/Fe] = 0.7 between CE- and CN-EMP stars, this condition suggests a physically meaningful boundary [C/Fe]_{b} = 2.30 above and below which carbon and silicate grains are dominant coolants, respectively.

description: We algebraically analysis the quantum Hall effect of a system of particles living on the disc ${\bf B}^1$ in the presence of an uniform magnetic field $B$. For this, we identify the non-compact disc with the coset space $SU(1,1)/U(1)$. This allows us to use the geometric quantization in order to get the wavefunctions as the Wigner ${\cal D}$-functions satisfying a suitable constraint. We show that the corresponding Hamiltonian coincides with the Maass Laplacian. Restricting to the lowest Landau level, we introduce the noncommutative geometry through the star product. Also we discuss the state density behavior as well as the excitation potential of the quantum Hall droplet. We show that the edge excitations are described by an effective Wess-Zumino-Witten action for a strong magnetic field and discuss their nature. We finally show that LLL wavefunctions are intelligent states.

description: Blister beetle poisoning (cantharidiasis) of horses has been well documented. Primary exposure to blister beetles is through consumption of contaminated lucerne hay. Confirmed cases of bovine cantharidiasis due to natural exposure have not previously been documented in veterinary literature. This report describes four cases of blister beetle poisoning in three dairy herds and one beef herd in New Mexico and Oklahoma, USA, that were reported between 1995 and 1999. Cows in two large dairy herds consumed blister beetles in a total mixed ration containing green chop lucerne. The most significant clinical signs were mass refusal to eat the freshly cut green chop lucerne, although the cows appeared hungry, and the corresponding dramatic decrease in milk production. Cows in a smaller dairy herd and a beef herd consumed large round bales of lucerne hay containing blister beetles. In contrast to cows exposed to the beetles in green chop, feed refusal in these cases was limited to individual cows. Other clinical signs included salivation, bruxism, frequent urination, diarrhoea, reluctance to move, abdominal pain, ataxia and recumbency. Postmortem examination did not reveal significant gross or microscopic lesions. Cantharidin was detected by gas chromatography-mass spectrometry analysis of either urine or feed samples. In addition, blister beetles were found in the lucerne green chop or hay.

description: WRKY transcription factors are important players in plant regulatory networks, where they control and integrate various physiological processes and responses to biotic and abiotic stresses. Here, we analysed six rose genomes of 5 different species (Rosa chinensis, R. multiflora, R. roxburghii, R. sterilis, and R. rugosa) and extracted a set of 68 putative WRKY genes, extending a previously published set of 58 WRKY sequences based on the R. chinensis genome. Analysis of the promoter regions revealed numerous motifs related to induction by abiotic and, in some cases, biotic stressors. Transcriptomic data from leaves of two rose genotypes inoculated with the hemibiotrophic rose black spot fungus Diplocarpon rosae revealed the upregulation of 18 and downregulation of 9 of these WRKY genes after contact with the fungus. Notably, the resistant genotype exhibited the regulation of 25 of these genes (16 upregulated and 9 downregulated), while the susceptible genotype exhibited the regulation of 20 genes (15 upregulated and 5 downregulated). A detailed RT–qPCR analysis of RcWRKY37, an orthologue of AtWRKY75 and FaWRKY1, revealed induction patterns similar to those of the pathogenesis-related (PR) genes induced in salicylic acid (SA)-dependent defence pathways in black spot inoculation experiments. However, the overexpression of RcWRKY37 in rose petals did not induce the expression of any of the PR genes upon contact with black spot. However, wounding significantly induced the expression of RcWRKY37, while heat, cold, or drought did not have a significant effect. This study provides the first evidence for the role of RcWRKY37 in rose signalling cascades and highlights the differences between RcWRKY37 and AtWRKY75. These results improve our understanding of the regulatory function of WRKY transcription factors in plant responses to stress factors. Additionally, they provide foundational data for further studies.
