    Biotechnological strategies to generate climate-smart crops: Recent advances and way forward
    (John Wiley & Sons, 2023) Maurya, Jyoti; Singh, Roshan Kumar; Prasad, Manoj
    Industrialization and other man-made actions caused accumulation of greenhouse gases in the atmospheric troposphere layer, leading to enhanced greenhouse effect and hike in average global temperature in response. This led to unpredicted and frequent occurrences of rainfall, droughts, floods, and other climatic events. Changing climate has imposed direct abiotic stresses leading severe threat to global crop production either directly (morpho-physio-chemical effects) or indirectly (socioeconomic effects) and caused food insecurity worldwide. Moreover, these climate change effects are predicted to become more severe in the future. So, to ensure the global food security, development of climate-smart crops is an urgent need. Biotechnology-based approaches have paved the way to understand the role of different genes and their applications to achieve climate change induced stress tolerance and developed crops for sustainable agriculture in the present scenario. Keeping this in mind, the present book chapter briefs about the effect of climate change on crop growth, development, and yield, as well as plant responses and adaptations during changing environments. This chapter also discusses different strategies implied to combat the climate change and highlights the integrative-omics based approach and biotechnological strategies, as well as their advancements toward generating the climate-smart crops.

    Complex networks of prion-like proteins reveal cross talk between stress and memory pathways in plants
    (Frontiers Media S.A., 2021) Garai, Sampurna; Citu; Singla-Pareek, Sneh L.; Sopory, Sudhir K.; Kaur, Charanpreet; Yadav, Gitanjali
    Prions are often considered as molecular memory devices, generating reproducible memory of a conformational change. Prion-like proteins (PrLPs) have been widely demonstrated to be present in plants, but their role in plant stress and memory remains unexplored. In this work, we report the widespread presence of PrLPs in plants through a comprehensive meta-analysis of 39 genomes representing major taxonomic groups. We find diverse functional roles associated with these proteins in various species and term the full complement of PrLPs in a genome as its “prionome.” In particular, we found the rice prionome being significantly enriched in transposons/retrotransposons (Ts/RTRs) and identified over 60 rice PrLPs that were differentially regulated in stress and developmental responses. This prompted us to explore whether and to what extent PrLPs may build stress memory. By integrating the available rice interactome, transcriptome, and regulome data sets, we could find links between stress and memory pathways that would not have otherwise been discernible. Regulatory inferences derived from the superimposition of these data sets revealed a complex network and cross talk between PrLPs, transcription factors (TFs), and the genes involved in stress priming. This integrative meta-analysis connects transient and transgenerational memory mechanisms in plants with PrLPs, suggesting that plant memory may rely upon protein-based signals in addition to chromatin-based epigenetic signals. Taken together, our work provides important insights into the anticipated role of prion-like candidates in stress and memory, paving the way for more focused studies for validating the role of the identified PrLPs in memory acclimation.
