Abstract	AIM: We used an eco‐phylogenetic approach to investigate the diversity and assembly patterns of tropical dry forests (TDFs) in Central India. We aimed at informing conservation and restoration practices in these anthropogenically disturbed forests by identifying potential habitats of conservation significance and elements of regional biodiversity most vulnerable to human impact and climate change. LOCATION: Tropical dry forests of Madhya Pradesh, Central India. METHODS: We analysed the species richness, stem density, basal area and phylogenetic structure (standardized effect size of MNTD, MPD, PD and community evolutionary distinctiveness cED) of 117 tree species assemblages distributed across a ~230 to ~940 m elevational gradient. We examined how these community measures and taxonomic (Sørensen) and phylogenetic (UniFrac) beta diversity varied with elevation, precipitation, temperature and climatic stress. RESULTS: Species richness, phylogenetic diversity, stem density and basal area were positively correlated with elevation, with high‐elevation plots exhibiting cooler temperatures, higher precipitation and lower stress. High‐elevation assemblages also trended towards greater phylogenetic dispersion, which diminished at lower elevations and in drier, more stressful plots. Phylogenetic turnover was observed across the elevation gradient, and species evolutionary distinctiveness increased at lower elevations and under harsher abiotic conditions. MAIN CONCLUSIONS: Harsher abiotic conditions at low elevations may act as a selective filter on plant lineages, leading to phylogenetically clustered low‐diversity assemblages. These assemblages contained more evolutionarily distinct species that may contribute disproportionately to biodiversity. Conversely, milder abiotic conditions at high elevations may serve as refuges for drought‐sensitive species, resulting in more diverse assemblages. Conservation practices that prioritize both high‐ and low‐elevation habitats could promote the persistence of evolutionarily distinct species and areas of high biodiversity within the Central Indian landscape. Establishing connectivity between these habitats may provide a range of climatic conditions for species to retreat to or persist within as climates change.

Abstract	Environmental heterogeneity is considered as one of the main drivers of habitat specialization and niche evolution among tropical plant lineages, and local‐scale habitat specialization promotes niche differentiation among sister taxa. In this study, we examined the degree to which habitat specialization leads to niche differentiation across the distribution range of a given species using five species of the family Myristicaceae native to Western Ghats, India, as an example. In the Western Ghats, Myristicaceae species occur in two main habitat types, namely, freshwater swamps (flooded habitat) and terra firme forest (non‐flooded habitat), distributed across a seasonal flooding gradient. First, we reconstructed the evolutionary history of flooded habitat specialization among global and Western Ghats Myristicaceae by mapping flooded habitat association and traits conferring flood tolerance (e.g., aerial roots) on a dated phylogeny. Then, we investigated climatic niche differences among lineages occupying flooded and terra firme habitats using occurrence data and environmental variables. Our analysis revealed swampy habitat occurrence as the probable ancestral state with subsequent speciation events leading to adaptation to non‐swampy habitats. We also show that traits conferring flood tolerance have evolved independently several times during the evolution of Myristicaceae. Furthermore, phylogenetically distantly related Myristicaceae taxa occupying different habitats (flooded and terra firme habitat) in Western Ghats show significant niche divergence. Overall, the repeated gain of swampy habitat specialization and associated morphological traits and evidence for habitat‐associated climatic niche divergence among Myristicaceae taxa suggest that seasonal flooding may have been an important driver of ecological diversification in this primitive plant family.

Abstract	Endophytic microbes are present in nearly all of the plant species known to date but how they enter and flourish inside a host plant and display multiple benefits like plant growth promotion (PGP), biodegradation, and stress alleviation are still unexplored. Until now, the majority of the research has been conducted assuming that the host–endophyte interaction is analogous to the PGP microbes, although, studies related to the mechanisms of their infection, colonization as well as conferring important traits to the plants are limited. It would be fascinating to explore the role of these endophytic microbes in host gene expression, metabolism, and the modulation of phenotypic traits, under abiotic and biotic stress conditions. In this review, we critically focused on the following areas: (i) endophytic lifestyle and the mechanism of their entry into plant tissues, (ii) how endophytes modulate the immune system of plants and affect the genotypic and phenotypic expression of host plants under abiotic and biotic stress condition, and (iii) the role of omics and other integrated genomic approaches in unraveling complex host–endophyte signaling crosstalk. Furthermore, we discussed their role in phytoremediation of heavy metal stress and whole genomic analysis based on an understanding of different metabolic pathways these endophytes utilize to combat stress.

Abstract	A comparative proteomic analysis was carried out to investigate the effects of various Light Emitting Diode (LED) light qualities (wavelengths), including red LED (R), blue LED (B), red (70%) + blue (30%) LED (RB), and white LED (W), on the wounding response in Arabidopsis thaliana. The majority of differentially expressed proteins were unique to each light condition. The highest (54%) and the lowest (22%) changes in total protein expression were observed in plants exposed to RB and B light, respectively. In wounded plants exposed to red + blue LED (RB) light, expression of antioxidant enzymes and a number of proteins related to dark reaction of photosynthesis decreased while the abundance of several proteins involved in the resistance to pathogen and lignin biosynthesis increased. Under blue LED (B) light, plants responded to wounding mainly through cell wall modification, biosynthesis of lignin and over expression of glutathione peroxidase. The results also indicated enhanced antioxidative capacity in response to wounding under red LED (R) light as compared to the other LED light conditions. The analyses of hormone metabolism suggested an increase in gibberellic acid (GA), abscisic acid (ABA) and salicylic acid (SA) signaling in the red + blue LED (RB), an enhancement in ethylene biosynthesis in the red LED (R), and increased jasmonic acid (JA) and brassinosteroid (BR) biosynthesis in the white LED (W) light conditions in response to wounding. Consistent with proteomic results related to JA metabolism, the highest concentration of methyl jasmonate (MeJA) was detected in white LED exposed plants. Late induction of JA biosynthesis-associated genes (AOC and AOS) in response to wounding was observed in all LED conditions, with the highest intensity in W light exposed plants. Collectively, we conclude that although white LED (W) light induces JA signaling pathway, red + blue LED (RB) light condition provides a better capability to recover from wound stress in A. thaliana. The results of H2O2 detection between different LED exposed plants showed different amounts of hydrogen peroxide production in response to wounding suggesting the possible signaling role of ROS in light-induced wound responses.

Abstract	Tropical forests are rich in biodiversity with great potential for carbon (C) storage. We estimated ecosystem-level C stock using data from 70 forest plots in three major forest types: tropical dry deciduous (TDD I and TDD II), tropical semi-evergreen (TSE I and TSE II) and tropical evergreen forests (TEF I, TEF II and TEF III) of Kanyakumari Wildlife Sanctuary, Western Ghats, India. The average C stock in these forests was 336.8 Mg C/ha, of which 231.3, 3.0, 2.4, 15.2 and 84.9 Mg C/ha were stored in woody vegetation, understorey, litter, deadwood and soil respectively. The live vegetation, detritus and soil contributed 65.5%, 5.5% and 29% respectively to the total ecosystem-level C stock and distributed in forest types in the order: TEF III > TEF II > TEF I > TSE I > TDD II > TSE II > TDD I. The plant diversity, structural attributes and environmental factors showed significant positive correlations with C stocks and accounted for 6.7, 77.2 and 16% of variance. These findings indicate that the tropical forests in the Western Ghats store large amount of C, and resulting data are invaluable for planning and monitoring forest conservation and management programs to enhance C storage in tropical forests.

Abstract	Despite numerous studies reporting endophytic fungal production of metabolites chemically similar to the secondary metabolites produced by their host plants, how and why the fungi produce these metabolites remain largely unknown. Here, we review the literature on endophytic fungal production of taxol and camptothecin, two extensively studied plant secondary metabolites, and highlight critical gaps in our knowledge that need to be addressed to adequately answer the above questions. We show that detailed studies are required for conclusive demonstration of i) the production of these metabolites by the fungi, ii) the tolerance of the fungi to the produced cytotoxic metabolites, and iii) the adaptive significance of the metabolite production to the fungi. Although our focus is on two widely studied plant secondary metabolites produced by fungi, the questions addressed here are equally applicable to the production of a large number of other fungal metabolites that are similar to those produced by their host plants.

Abstract	Citron (Citrus medica L.) is a medicinally important species of citrus native to India and occurs in natural forests and home gardens in the foothills of the eastern Himalayan region of northeast India. The wild populations of citron in the region have undergone rapid decline due to natural and anthropogenic disturbances and most of the remaining individuals of citron are found in fragmented natural forests and home gardens in the region. In order to assess the genetic structure and diversity of citron in wild and domesticated populations, we analyzed 219 individuals of C. medica collected from four wild and eight domesticated populations using microsatellite markers. The genetic analysis based on five polymorphic microsatellite loci revealed an average of 13.40 allele per locus. The mean observed and expected heterozygosity values ranged between 0.220-0.540 and 0.438-0.733 respectively among the wild and domesticated populations. Domesticated populations showed close genetic relationships as compared to wild populations and pairwise Nei's genetic distance ranged from 0.062 to 2.091 among wild and domesticated populations. Analysis of molecular variance (AMOVA) showed higher genetic diversity among- than within populations. The analysis of population structure revealed five groups. Mixed ancestry of few individuals of different populations revealed exchange of genetic materials among farmers in the region. Citron populations in the region show high genetic variation. The knowledge gained through this study is invaluable for devising genetically sound strategies for conservation of citron genetic resources in the region.
