Item Knockdown of type 2 orexin receptor in adult mouse testis potentiates testosterone production and germ cell proliferation(Elsevier Ireland Ltd, 2024) Sahoo P.; Sarkar D.; Sharma S.; Verma A.; Naik S.K.; Prashar V.; Parkash J.; Singh S.K.Orexins (OXs) are neuropeptides which regulate various physiological processes. OXs exist in two different forms, mainly orexin A (OXA) and orexin B (OXB) and their effects are mediated via OX1R and OX2R. Presence of OXB and OX2R in mouse testis is also reported. However, the role of OXB/OX2R in the male gonad remains unexplored. Herein we investigated the role of OXB/OX2R system in testicular physiology under in vivo and ex vivo conditions. Adult mice were given a single dose of bilateral intratesticular injection of siRNA targeting OX2R and were sacrificed 96 h post-injection. OX2R-knockdown potentiated serum and intratesticular testosterone levels with up-regulation in the expressions of major steroidogenic proteins. Germ cell proliferation also increased in siRNA-treated mice. Results of the ex vivo experiment also supported the findings of the in vivo study. In conclusion, OX2R may regulate testosterone production and thereby control the fine-tuning between steroidogenesis and germ cell dynamics. � 2024 Elsevier B.V.Item Regenerative Agriculture: Translating Science to Action(CRC Press, 2024) Rakshit A.; Parihar M.; Meena V.S.; Jha P.K.; Sarkar D.; Abhilash P.C.This book aims to focus on the current state of knowledge and scientific advances about the complex and intertwined issues of regenerative farming as a transformative solution for offsetting the disastrous climate effects of burning fossil fuels and impairments of natural resource bases. Regenerative agriculture advocates no-till practices, planting cover crops, integrating livestock and crop production, improving animal welfare practices, improving the social and economic well-being of communities, sequestering carbon, improving soil health, and increasing yields and profit with a positive impact on food access or food safety regardless of farm size. This book examines the innovations that will equip agriculture to cope with the competing challenges of addressing food and nutrition security, improving livelihoods, combatting climate change, and sustainably managing natural resources. The scope of this book extends to agricultural scientists, students, consultants, site owners, industrial stakeholders, regulators, and policymakers. � 2024 selection and editorial matter, Amitava Rakshit, Manoj Parihar, Vijay Singh Meena, Prakash Kumar Jha, Deepranjan Sarkar, and Purushothaman Chirakkuzhyil Abhilash.Item Trichoderma as a potent bioprimer for horticultural crops(Elsevier, 2024) Singh J.; Paul S.; Barnwal P.; Kumari S.; Sarkar D.; Parihar M.; Meena V.S.; Rakshit A.In current changing agricultural production system increased use of agrochemicals to prevent plant diseases, pests for enhancing the crop production has become a major concern. The current farming practices are having significant impact on pest and disease resurgence, reduced soil organic carbon leading to degraded soil health, and has detrimental effects on ecosystem. Therefore, one of the feasible alternatives is microbial intervention in crop production. Numerous bacteria and fungi, especially endophytic fungi, work as plant-growth-promoting rhizobacteria. Among the scientists and farmers microbial inoculants products based on Trichoderma are getting emphasis because of their potential to increase crop output, nutritional quality, and resistance to a variety of environmental challenges like pests and plant pathogens. Moreover, Trichoderma as bioinoculant has much higher potential to be disseminated and used at mass level as its culture preparation, multiplication, and application is very simple resulting to become more adaptable to the farmers. In this chapter, numerous horticultural crops have been extensively explored for the use of Trichoderma species as bioinoculant. They also enhance soil fertility and control pathogens, among other advantages. However, there are numerous commercial formulations of Trichoderma sp. available in the market. Multiple carrier materials, including talc, plant growth medium (PGM), rice bran, coco peat, and coconut husk, are utilized to extend the shelf life of microbial products. The usage of Trichoderma sp. carrier formulation varies depending on the crop�s adaptability, its availability, and the farmer�s preference. Talc-based formulations are frequently utilized among the many Trichoderma formulations. � 2024 Elsevier Inc.

Unfortunately, there is little study and fragmented information available about these naturally edible products. The UEFS of the IGP was the subject of a systematic review utilizing the PRISMA protocol, which produced implications for FS and land degradation neutrality (LDN). This review aims to survey, summarize, and annotate the published information about the angiosperms native and naturalized UEFS of IGP to identify and make use of this species, particularly for the sustainable development of this region. A systematic review confirmed that 371 species of UEFS, of which 62 species were threatened and near threatened (TNT)-UEFS. Among the TNT-UEFS, 41 species were threatened, while 21 species were NT. The threatened species were further categorized as per the International Union for Conservation of Nature (IUCN) Red List in the IGP as vulnerable (21 species), endangered (16 species), and critically endangered (four species). This systematic review suggests integration of the native and naturalized UEFS in afforestation and reforestation programs to aid in various ecosystem services. Calamus inermis, Corypha taliera, Licuala peltata, and Saurauia punduana are examples of multipurpose species that require immediate sustainable conservation and cultivation initiatives to save them from extinction in the near future. Multipurpose species such as Aegle marmelos, Buchanania lanzan, Manilkara hexandra, Syzygium cuminii, Tamarindus indica are immensely constructive and climate-smart by surviving in harsh agroclimatic conditions and have great potential for establishment on marginal and wastelands throughout the IGP region. These resilient fruit species enhance biodiversity, ecosystems, and landscapes in addition to providing food for humans. It progressively advances India�s commitment to LDN, combating climate change, and achieving the UN-SDGs, which call for reducing hunger and raising FS by 2030. As a result, the study will offer baseline data for the next investigations and be helpful to policymakers in creating sustainable and scientific policies for the IGP. � T�B?TAK.
