    Abstract: Withania coagulans (Stocks) Dunal is used in traditional medicine to treat diseases and has numerous pharmacological properties due to its biological compounds. The plant is a subshrub native to Asia, especially the tropical and temperate regions of western Asia. Its medicinal effects derive from its biological components, which are linked to human health. Conventional medicine uses these compounds to treat a variety of diseases, such as neurological issues, diabetes, and asthma. The long-term benefits of W. coagulans necessitate conservation strategies and plant biotechnological techniques such as micropropagation, synthetic seed, cell suspension, and hairy root elicitation technology, and genetic transformation can all play significant roles in conservation and sustainable utilization of the biological compounds for clinical uses. The objective of this review is to provide a comprehensive overview of the W. cogaulans medicinal properties, potential applications, and innovative approaches for sustainable utilization, making it a unique contribution to the existing body of knowledge. Multi-omics methods for the production of withanolides were also examined in order to gain a better understanding of the genome structure, prospective genes, and candidate proteins involved in the production.

    Abstract: LTR retrotransposons play a significant role in plant growth, genome evolution, and environmental stress response, but their regulatory response to heat stress remains unclear. We have investigated the activities of two LTR retrotransposons, PHRE1 and PHRE2 , of moso bamboo ( Phyllostachys edulis ) in response to heat stress. Results The differential overexpression of PHRE1 and PHRE2 with or without CaMV35s promoter showed enhanced expression under heat stress in transgenic plants. The transcriptional activity studies showed an increase in transposition activity and copy number among moso bamboo wild type and Arabidopsis transgenic plants under heat stress. Comparison of promoter activity in transgenic plants indicated that 5’LTR promoter activity was higher than CaMV35s promoter. Additionally, yeast one-hybrid (Y1H) system and in planta biomolecular fluorescence complementation (BiFC) assay revealed interactions of heat-dependent transcription factors (TFs) with 5’LTR sequence and direct interactions of TFs with pol and gag . Conclusions Our results conclude that the 5’LTR acts as a promoter and could regulate the LTR retrotransposons in moso bamboo under heat stress.

    Abstract: Understanding plant stress memory under extreme temperatures such as cold and heat could contribute to plant development. Plants employ different types of stress memories, such as somatic, intergenerational and transgenerational, regulated by epigenetic changes such as DNA and histone modifications and microRNAs (miRNA), playing a key role in gene regulation from early development to maturity. In most cases, cold and heat stresses result in short-term epigenetic modifications that can return to baseline modification levels after stress cessation. Nevertheless, some of the modifications may be stable and passed on as stress memory, potentially allowing them to be inherited across generations, whereas some of the modifications are reactivated during sexual reproduction or embryogenesis. Several stress-related genes are involved in stress memory inheritance by turning on and off transcription profiles and epigenetic changes. Vernalization is the best example of somatic stress memory. Changes in the chromatin structure of the Flowering Locus C ( FLC ) gene, a MADS-box transcription factor (TF), maintain cold stress memory during mitosis. FLC expression suppresses flowering at high levels during winter; and during vernalization, B3 TFs, cold memory cis -acting element and polycomb repressive complex 1 and 2 (PRC1 and 2) silence FLC activation. In contrast, the repression of SQUAMOSA promoter-binding protein-like ( SPL ) TF and the activation of Heat Shock TF ( HSFA2 ) are required for heat stress memory. However, it is still unclear how stress memory is inherited by offspring, and the integrated view of the regulatory mechanisms of stress memory and mitotic and meiotic heritable changes in plants is still scarce. Thus, in this review, we focus on the epigenetic regulation of stress memory and discuss the application of new technologies in developing epigenetic modifications to improve stress memory.

    Abstract: The ATP-binding cassette subfamily B (ABCB) is an important transporter family, and many members are well known for their auxin transport function. However, reports on the function of the ABCB genes during Moso bamboo development are few. In this study, we identified and characterized 37 PhABCB genes in Moso bamboo and classified them into five subgroups, Ⅰ–Ⅴ. We further observed gene family expansion and gene loss events during the evolution of the PhABCB gene family. It was found that the expansion of the PhABCB family was mainly attributed to the whole-genome duplication and DNA-transposed duplication models. Gene co-expression analysis and quantitative real-time PCR revealed that several PhABCB genes may be involved in the development of the secondary cell wall (SCW) during the rapid growth of Moso bamboo. Through examining their expression in different parts of the bamboo internode where the cell walls exhibited different developmental stages, the roles of eight candidate PhABCBs in the SCW development were further characterized. Of the eight PhABCB genes, PhABCB7, PhABCB11, PhABCB14, and PhABCB21 may be involved in the SCW biogenesis in Moso bamboo. This study provides the basis for discovering the potential role of PhABCB genes in Moso bamboo cell wall development; further studies are needed to elucidate how these PhABCBs function in SCW development by regulating the polar transport of auxin.

    Abstract: Plant development processes are regulated by epigenetic alterations that shape nuclear structure, gene expression, and phenotypic plasticity; these alterations can provide the plant with protection from environmental stresses. During plant growth and development, these processes play a significant role in regulating gene expression to remodel chromatin structure. These epigenetic alterations are mainly regulated by transposable elements (TEs) whose abundance in plant genomes results in their interaction with genomes. Thus, TEs are the main source of epigenetic changes and form a substantial part of the plant genome. Furthermore, TEs can be activated under stress conditions, and activated elements cause mutagenic effects and substantial genetic variability. This introduces novel gene functions and structural variation in the insertion sites and primarily contributes to epigenetic modifications. Altogether, these modifications indirectly or directly provide the ability to withstand environmental stresses. In recent years, many studies have shown that TE methylation plays a major role in the evolution of the plant genome through epigenetic process that regulate gene imprinting, thereby upholding genome stability. The induced genetic rearrangements and insertions of mobile genetic elements in regions of active euchromatin contribute to genome alteration, leading to genomic stress. These TE-mediated epigenetic modifications lead to phenotypic diversity, genetic variation, and environmental stress tolerance. Thus, TE methylation is essential for plant evolution and stress adaptation, and TEs hold a relevant military position in the plant genome. High-throughput techniques have greatly advanced the understanding of TE-mediated gene expression and its associations with genome methylation and suggest that controlled mobilization of TEs could be used for crop breeding. However, development application in this area has been limited, and an integrated view of TE function and subsequent processes is lacking. In this review, we explore the enormous diversity and likely functions of the TE repertoire in adaptive evolution and discuss some recent examples of how TEs impact gene expression in plant development and stress adaptation.

    Abstract: Sustainable goals for contemporary world seek viable solutions for interconnected challenges, particularly in the fields of food and energy security and climate change. We present bamboo, one of the versatile plant species on earth, as an ideal candidate for bioeconomy for meeting some of these challenges. With its potential realized, particularly in the industrial sector, countries such as China are going extensive with bamboo development and cultivation to support a myriad of industrial uses. These include timber, fiber, biofuel, paper, food, and medicinal industries. Bamboo is an ecologically viable choice, having better adaptation to wider environments than do other grasses, and can help to restore degraded lands and mitigate climate change. Bamboo, as a crop species, has not become amenable to genetic improvement, due to its long breeding cycle, perennial nature, and monocarpic behavior. One of the commonly used species, moso bamboo ( Phyllostachys edulis ) is a potential candidate that qualifies as industrial bamboo. With its whole‐genome information released, genetic manipulations of moso bamboo offer tremendous potential to meet the industrial expectations either in quality or in quantity. Further, bamboo cultivation can expect several natural hindrances through biotic and abiotic stresses, which needs viable solutions such as genetic resistance. Taking a pragmatic view of these future requirements, we have compiled the present status of bamboo physiology, genetics, genomics, and biotechnology, particularly of moso bamboo, to drive various implications in meeting industrial and cultivation requirements. We also discuss challenges underway, caveats, and contextual opportunities concerning sustainable development.

    Abstract: Morphometric character analyses and RAPD was used to discriminate and ratify the status of three populations of Indian salmon, Polydactylus plebeius along the coromandel coast of India. Morphometric analyses showed a clear pattern of differentiation between the stocks and revealed the discreteness of two groups, southern stock (Pazhayar) and northern stock (Cuddalore). The univariate analysis of variance showed significant differences between means of the samples for most morphometric descriptors. A total of 1077 scorable bands were produced using all ten arbitrary primers in three populations. An un-weighted pair-group method with arithmetic mean (UPGMA) dendrogram was constructed based on genetic values to show the genetic relationship among the three populations. The genetic diversity (H) of P. plebeius in Cuddalore was more (0.0733 ± 0.0648) than Pazhayar (0.0609 ± 0.0416) and Vellar (0.0613 ± 0.0344) populations. All the three populations had significantly (p

    Abstract: Planktonic larvae were captured in the shallow Vellar estuary, Tamilnadu, India, during January to June 2013 using zooplankton net. Larvae were identified to the species level by comparison with Genbank data base using MtDNA sequence data. Further analysis showed that there is no sequence variation within-species, whereas between-species variation was more than 25%, supporting the suitability for species identification. The highest genetic distance was observed between A. nigropunctatus and M. cephalus (0.434) and the lowest genetic distance was observed between T. jarbua and S. commersoni (0.256). Given the current worldwide interest in DNA barcoding and species identification using MtDNA gene marker (CO1), it was confirmed the efficacy of the Fish-F1 and -R1 primer set, which gave the possibility for identification of finfish larvae at species level.
