Metabolite profiling in Mango (Mangifera indica L.) pollen grains in relation to viability

Mango productivity is affected mainly by irregular flowering, proportion of bisexual flowers, poor pollination and fertilization and fruit drop. Poor fruit set in some of the varieties may be associated with the lower pollen viability. The present experiment was initiated to assess the viability of pollen grains and their metabolites in three mango cultivars Amrapali, Alphonso and Totapuri which are differing in their fruit set intensity. The profiling of sugars, amino acids and some of the phytohormones were analysed using Liquid Chromatography-Mass Spectrometry (LC-MS/MS). Assessment of pollen grains in three mango cultivars indicated that free sugars such as fructose and glucose, and available amino acids including serine, proline, lysine, phenylalanine, alanine and glutamic acid were predominantly higher in all the cultivars. Phytohormones like IAA, IBA, ABA, GA,zeatin, jasmonic acid and salicylic acid were significantly different in low fruit setting cultivars Alphonso and Totapuri compared to high fruit setting cultivar Amrapali. In cv. Alphonso all the metabolites were higher at anthesis but later decreased drastically compared to cvs. Totapuri and Amrapali. Pollen viability percentage was significantly higher in cv. Amrapali than in cvs. Totapuri, Alphonso. Among all the cultivars, Amrapali maintained better chemical composition at anthesis and also at two hours after anthesis compared to cvs. Totapuri and Alphonso.
Babesia , a Tick Transmitted Zoonotic Disease in Falcons

A pair of the domesticated falcons Laggar falcons (Falco jugger ) from the District Jhang, Pakistan was presented with the history and the clinical conditions of the high rise in the body temperature, letharginess, signs of paralysis, off feed from 2 days and the pale colored conjunctiva was presented. Suspected case of the Babesia was confirmed and treated. The bird showed complete recovery. This is the relatively uncommon presentation of such case in avian family.
Microcystin-LR: Effects on Freshwater Catfish Heteropneustes fossilis Prolactin Cells

Background: Previous studies have been reported on the toxicity of Microcystin-LR, which is produced by cyanobacterial growth in fish, such as Heteropneustes fossilis (H. fossilis). However, no studies have been conducted on the effects of Microcystin-LR on the prolactin cells of H. fossilis. Methods: H. fossilis fish were intraperitoneally injected with Microcystin-LR (2.5μg/25g) and sacrificed after 1, 3, 5, 10 and 15 days. The blood samples were analyzed for the calcium levels. Histological slides of the pituitary prolactin cells were stained with Herlant’s tetrachrome and Heidenhan’s azan techniques, and examined under light microscopy. Results: The prolactin cells exposed to Microcystin-LR exhibited no structural changes on day 1. However, hyperactive prolactin cells exhibited cellular degranulation from day 3 to day 5. On days 10 and 15, degenerated and vacuolated prolactin cells were also observed. The nuclear volume of prolactin cells exposed to MC-LR increased progressively from day 3 to day 10 but on day 15 the nuclear volume returned to normal. The serum calcium level of MC-LR injected specimens showed hypocalcemia from day 3 to day 10. On day 15, the level became normal. Conclusions: Our results indicated that the serum calcium levels and prolactin cells were altered after exposure to microcystin-LR.
BIOLOGICAL CONTROL OF COFFEE STEM BORERS, XYLOTRECHUS QUARDRIPES AND ACALOLEPTA CERVINUS, BY BEAUVERIA BASSIANA PREPARATION

The use of Beauveria bassiana proparations for control of coffee stem borers, Xylotrechus quardripes Chevr. and Acalolepta cervinus (Hope), as tested in the laboratory and field conditions. The results show that each instar of coffee stem borers could be infected and killed successfully when being inoculated or contacted with B. bassiana . The control efficacy under indoor cultivation conditions exceeded 90% within 15 days. Jamming drilled hole with fungal mud resulted in the accumulative mortality and corrected mortality of 90% within 20 days. In the field, three methods, jamming drilled holes with bamboo sticker, bamboo sticker with fungal mud, and fungal mud only, were employed, and each led to the control effect of 90% within 20 days. However, spraying suspensions and dusting powder of B. bassiana was insignificant. The yield of fresh coffee fruits in biological control area was 125 7? kg/0 067? ha greater than that of control area when being harvested in February. Compared the cost of microbial control with that of chemical control, B. bassiana proved to be a profitable, effective, and safe biocontrol agent against coffee stem borer.
Mitochondrial Genetic Diversity of Bat Species from the Maltese Islands and Applications for their Conservation

This work presents the first genetic species identification and phylogenetic analyses of all six bat species known to inhabit the Maltese archipelago. The results provide a DNA-based reference library of 12S rRNA, 16S rRNA, COI, Cytb and ND1 mitochondrial sequences for Maltese bat species. Phylogenetic analyses revealed that the Maltese bat populations do not harbour cryptic diversity. Analyses of genetic diversity for Maltese bat species showed contrasting matrilineal diversity between species, Hypsugo savii exhibited the highest haplotype diversity (Hd = 0.802), while Rhinolophus hipposideros showed no haplotype diversity and Plecotus gaisleri exhibited low values for haplotype diversity (Hd = 0.091). Comparative phylogeographical analyses of mtDNA gene datasets from this study with sequences of conspecific bat populations outside of Malta indicate that mitochondrial haplotypes of Pipistrellus pipistrellus and Rhinolophus hipposideros are unique to the Maltese Islands. Hypsugo savii, Pipistrellus kuhlii, Myotis punicus and Plecotus gaisleri shared the most common mitochondrial haplotype with surrounding geographical areas, including the Ibero-Maghreb region, the Apennine Peninsula and Sicily. The observed genetic diversity and phylogenetic relationships are discussed in the context of the species’ biology and long-term conservation planning of Maltese bat populations.
MyD88-Syk axis is a critical determinant for inflammatory response in macrophages

Inflammation, a vital immune response to infection and injury, is mediated by macrophage activation. Spleen tyrosine kinase (Syk) and myeloid differentiation primary response 88 (MyD88) regulate the inflammatory response in macrophages, however, their roles and the underlying mechanisms are still largely unknown. In this study, the role of the MyD88-Syk axis and the mechanism by which Syk and MyD88 cooperate during macrophage-mediated inflammatory responses were investigated. Inhibition of Syk or MyD88 decreased both generation of reactive oxygen species (ROS)/reactive nitrogen species (RNS) and consequent ROS/RNS-induced phagocytic activity in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Syk inhibition downregulated expression of ROS/RNS-generating enzymes by inhibiting the nuclear factor-kappa B (NF-κB) signaling pathway and phagocytic activity by suppressing suppressor of cytokine signaling 1 (SOCS1) via its nitration in the LPS-stimulated RAW264.7 cells. Inhibition of ROS/RNS generation suppressed SOCS1 nitration, leading to a decrease in the phagocytic activity of macrophages. Syk was activated by the interaction with MyD88, and the tyrosine 58 residue (Y58) in the hemi-immunoreceptor tyrosine-based activation motif (ITAM) of MyD88 was critical for their interaction and the consequent activation of Syk in macrophages. Src activated MyD88 by phosphorylation at Y58 via the Src kinase domain. Moreover, LPS-induced formation of filamentous actin (F-actin) and Ras-related C3 botulinum toxin substrate 1 (Rac1) activation induced Src activation. Conclusively, these results suggest that the MyD88-Syk axis plays a pivotal role in macrophage-mediated inflammatory responses by inducing ROS/RNS generation and phagocytic activity via activation of Src and its upstream stimulators, F-actin and Rac1.
Leaf drought tolerance cannot be inferred from classic leaf traits in a tropical rainforest

Plants are enormously diverse in their traits and ecological adaptation, even within given ecosystems, such as tropical rainforests. Accounting for this diversity in vegetation models poses serious challenges. Global plant functional trait databases have highlighted general trait correlations across species that have considerably advanced this research program. However, it remains unclear whether trait correlations found globally hold within communities, and whether they extend to drought tolerance traits. For 134 individual plants spanning a range of sizes and life forms (tree, liana, understorey species) within an Amazonian forest, we measured leaf drought tolerance (leaf water potential at turgor loss point, πtlp), together with 17 leaf traits related to various functions, including leaf economics traits and nutrient composition (leaf mass per area, LMA; and concentrations of C, N, P, K, Ca and Mg per leaf mass and area), leaf area, water‐use efficiency (carbon isotope ratio), and time‐integrated stomatal conductance and carbon assimilation rate per leaf mass and area. We tested trait coordination and the ability to estimate πtlp from the other traits through model selection. Performance and transferability of the best predictive model were assessed through cross‐validation. Here πtlp was positively correlated with leaf area, and with N, P and K concentrations per leaf mass, but not with LMA or any other studied trait. Five axes were needed to account for >80% of trait variation, but only three of them explained more variance than expected at random. The best model explained only 30% of the variation in πtlp, and out‐sample predictive performance was variable across life forms or canopy strata, suggesting a limited transferability of the model. Synthesis. We found a weak correlation among leaf drought tolerance and other leaf traits within a forest community. We conclude that higher trait dimensionality than assumed under the leaf economics spectrum may operate among leaves within plant communities, with important implications for species coexistence and responses to changing environmental conditions, and also for the representation of community diversity in vegetation models.
Neural correlates of goal-directed and non–goal-directed movements

Significance Although the monkey frontal eye field is implicated in the voluntary control of saccades, we found that only for during goal-directed saccades the variability in spike rate across trials decreased and had a concurrent reduction of LFP beta-band power, and the neural activity increased earlier. These data indicate the presence of additional constraints and computations that distinguish goal-directed movements from non–goal-directed movements. What are the cortical neural correlates that distinguish goal-directed and non–goal-directed movements? We investigated this question in the monkey frontal eye field (FEF), which is implicated in voluntary control of saccades. Here, we compared FEF activity associated with goal-directed (G) saccades and non–goal-directed (nG) saccades made by the monkey. Although the FEF neurons discharged before these nG saccades, there were three major differences in the neural activity: First, the variability in spike rate across trials decreased only for G saccades. Second, the local field potential beta-band power decreased during G saccades but did not change during nG saccades. Third, the time from saccade direction selection to the saccade onset was significantly longer for G saccades compared with nG saccades. Overall, our results reveal unexpected differences in neural signatures for G versus nG saccades in a brain area that has been implicated selectively in voluntary control. Taken together, these data add critical constraints to the way we think about saccade generation in the brain.
Distribution of Rutin and Protodioscin in Different Tissue Parts of Asparagus (Asparagus officinalis L.)

Asparagus is a popular vegetable rich in healthy functional components. Asparagus spears are known to contain a large amount of rutin, which has been found to possess anti-inflammatory, antitumor, and antibacterial/viral properties, and protodioscin, which is an antitumor substance and present in the bottom parts (8 cm from the cut end). However, the process of its production leaves fern in the aboveground parts and roots in the underground parts as significant amounts of nonusable parts, and this issue should be solved. This study was conducted to examine the distributions of rutin and protodioscin, representative functional components in different parts of asparagus. The results suggested that large amounts of rutin were noted in the cladophylls and storage roots (brown and epidermis), and the protodioscin content was high in the buds, the soil-covered section of the spear, and the rhizome. A significant amount of rutin was detected in the aboveground parts, which is consistent with the results of previous studies, but it was also found in the storage roots. The largest amount of protodioscin was found in the buds, as well as in young fruits and seeds of the aboveground parts. Injury by continuously cropping asparagus may be associated with high rutin content in the storage roots of asparagus.
Diversity and distribution of Pleioplectron Hutton cave wētā (Orthoptera: Rhaphidophoridae: Macropathinae), with the synonymy of Weta Chopard and the description of seven new species

The genus Pleioplectron was first described by Hutton (1896) and included six New Zealand species. This genus has since had three species moved, one each to the genera Pachyrhamma Brunner von Wattenwyl, 1888, Miotopus Hutton, 1898 and Novoplectron Richards, 1958. Here we clarify the status and appearance of Pleioplectron simplex Hutton, 1896 (incl. P. pectinatum Hutton, 1896 syn. nov.) and P. hudsoni Hutton, 1896, as well as P. thomsoni (Chopard, 1923) comb. nov., which is transferred from the genus Weta Chopard, 1923. The genus Weta is newly synonymised with Pleioplectron. We also describe seven new species of Pleioplectron from South Island, New Zealand: P. auratum sp. nov., P. caudatum sp. nov, P. crystallae sp. nov., P. flavicorne sp. nov., P. gubernator sp. nov., P. rodmorrisi sp. nov and P. triquetrum sp. nov. We base these descriptions on morphology using fresh specimens of both male and female adults, and provide support for each with DNA sequence variation (mtDNA, partial COI).
MOFA+: a probabilistic framework for comprehensive integration of structured single-cell data

Technological advances have enabled the joint analysis of multiple molecular layers at single cell resolution. At the same time, increased experimental throughput has facilitated the study of larger numbers of experimental conditions. While methods for analysing single-cell data that model the resulting structure of either of these dimensions are beginning to emerge, current methods do not account for complex experimental designs that include both multiple views (modalities or assays) and groups (conditions or experiments). Here we present Multi-Omics Factor Analysis v2 (MOFA+), a statistical framework for the comprehensive and scalable integration of structured single cell multi-modal data. MOFA+ builds upon a Bayesian Factor Analysis framework combined with fast GPU-accelerated stochastic variational inference. Similar to existing factor models, MOFA+ allows for interpreting variation in single-cell datasets by pooling information across cells and features to reconstruct a low-dimensional representation of the data. Uniquely, the model supports flexible group-level sparsity constraints that allow joint modelling of variation across multiple groups and views. To illustrate MOFA+, we applied it to single-cell data sets of different scales and designs, demonstrating practical advantages when analyzing datasets with complex group and/or view structure. In a multi-omics analysis of mouse gastrulation this joint modelling reveals coordinated changes between gene expression and epigenetic variation associated with cell fate commitment.

Influence of Root Distribution on Preferential Flow in Deciduous and Coniferous Forest Soils

Root-induced channels are the primary controlling factors for rapid movement of water and solute in forest soils. To explore the effects of root distribution on preferential flow during rainfall events, deciduous (Quercus variabilis BI.) and coniferous forest (Platycladus orientalis (L.) Franco) sites were selected to conduct dual-tracer experiments (Brilliant Blue FCF and Bromide [Br−]). Each plot (1.30 × 1.30 m) was divided into two subplots (0.65 × 1.30 m), and two rainfall simulations (40 mm, large rainfall and 70 mm, extreme rainfall) were conducted in these. Vertical soil profiles (1.00 m × 0.40 m) were excavated, and preferential flow path features were quantified based on digital image analysis. Root (fine and coarse) abundance and Br− concentration were investigated for each soil profile. In deciduous forest, accumulated roots in the upper soil layer induce larger lateral preferential flow as compared to the coniferous forest soil during large rainfall events. Compared with deciduous forest, coniferous forest soil, with higher (horizontal and vertical) spatial variability of preferential flow paths, promotes higher percolation and solute leaching to deeper soil layers during extreme rainfall events. Fine roots, accounting for a larger proportion of total roots (compared to coarse roots), facilitate preferential flow in the 0–40 cm forest soil layer. Overall, our results indicate that the root distribution pattern of different tree species can exert diverse effects on preferential flow in forest soils.
CamoGAN: Evolving optimum camouflage with Generative Adversarial Networks

One of the most challenging issues in modelling the evolution of protective colouration is the immense number of potential combinations of colours and textures. We describe CamoGAN, a novel method to exploit Generative Adversarial Networks to simulate an evolutionary arms race between the camouflage of a synthetic prey and its predator. Patterns evolved using our methods are shown to provide progressively more effective concealment and outperform two recognized camouflage techniques, as validated by using humans as visual predators. We believe CamoGAN will be highly useful, particularly for biologists, for rapidly developing and testing optimal camouflage or signalling patterns in multiple environments.
Acute Toxicity of Glyphosate Herbicide on Nile Tilapia (Oreochromis niloticus)

The constant discharge of agricultural wastes into the aquatic environment has led to accumulation of the herbicides, pesticides, heavy metals and other variety of pollutants. Herbicides present in these wastes are washed down, carried by rains and flood to nearby aquatic environment. In the world today, glyphosate is the most widely used herbicide and its consumption has increased to about 95% in the period from the year 2000 to 2004 (Ali Sani and Muhammad, 2016; and Adedeji and Okocha, 2012). The consumption of glyphosate pesticide in India is 180 MT in 2001 – 2002 and 210 MT in 2005 – 06.

The effects of age on resting-state BOLD signal variability is explained by cardiovascular and cerebrovascular factors

Accurate identification of brain function is necessary to understand neurocognitive ageing, and thereby promote health and well-being. Many studies of neurocognitive aging have investigated brain function with the blood-oxygen level-dependent (BOLD) signal measured by functional magnetic resonance imaging. However, the BOLD signal is a composite of neural and vascular signals, which are differentially affected by aging. It is therefore essential to distinguish the age effects on vascular versus neural function. The BOLD signal variability at rest (known as resting state fluctuation amplitude, RSFA), is a safe, scalable and robust means to calibrate vascular responsivity, as an alternative to breath-holding and hypercapnia. However, the use of RSFA for normalization of BOLD imaging assumes that age differences in RSFA reflecting only vascular factors, rather than age-related differences in neural function (activity) or neuronal loss (atrophy). Previous studies indicate that two vascular factors, cardiovascular health and cerebrovascular function, are insufficient when used alone to fully explain age-related differences in RSFA. It remains possible that their joint consideration is required to fully capture age differences in RSFA. We tested the hypothesis that RSFA no longer varies with age after adjusting for a combination of cardiovascular and cerebrovascular measures. We also tested the hypothesis that RSFA variation with age is not associated with atrophy. We used data from the population-based, lifespan Cam-CAN cohort. After controlling for cardiovascular and cerebrovascular estimates alone, the residual variance in RSFA across individuals was significantly associated with age. However, when controlling for both cardiovascular and cerebrovascular estimates, the variance in RSFA was no longer associated with age. Grey matter volumes did not explain age-differences in RSFA, after controlling for cardiovascular health. The results were consistent between voxel-level analysis and independent component analysis. Our findings indicate that cardiovascular and cerebrovascular signals are together sufficient predictors of age differences in RSFA. We suggest that RSFA can be used to separate vascular from neuronal factors, to characterise neurocognitive aging. We discuss the implications and make recommendations for the use of RSFA in the research of aging.
Genetic Screening Approaches to Cancer Driver Characterization and Synthetic Lethal Target Discovery

Advances in genetic screening technology have expanded the toolkit for systematic perturbation of gene function. While the CRISPR-Cas9 system robustly probes genetic loss-of-function in mammalian cells, a barcoded ORFeome library offers the opportunity to systematically study genetic gain-of-function. We employed these two screening tools for three purposes. First, we performed shRNA and CRISPR-based screens for synthetic lethality with BRCA2 deficiency, in two pairs of BRCA2 isogenic cell lines. BRCA2 mutation commonly drives hereditary breast and ovarian cancer, but also creates vulnerability to PARP inhibitor treatment. Among other genes, we found the AP endonuclease APEX2 and the flap endonuclease FEN1 to be synthetic lethal with BRCA2 deficiency; the base excision repair (BER) pathway was synthetic lethal overall. We demonstrated that FEN1 plays a role in microhomology-mediated end joining (MMEJ) and that a FEN1 inhibitor selectively targets BRCA-deficient cells, offering therapeutic potential in the setting of PARP inhibitor resistance. Second, we screened a barcoded ORFeome library for genes that either upregulate PD-L1 or interfere with IFNγ signaling. Tumor-expressed PD-L1 engages PD-1 on T cells, dampening T-cell based immune responses to tumors, while defects in
