    Genome editing for nutritional improvement of crops
    (John Wiley & Sons, 2024) Shekhawat, Pooja Kanwar; Ram, Hasthi; Soni, Praveen
    Genome editing techniques have offered excellent opportunities to develop new crop varieties with enhanced growth, productivity, stress tolerance, and quality. Targeted alterations in nutrition-related traits can provide a big solution for mitigating hidden hunger and ensuring nutritional security. Compared to traditional breeding methods, these novel techniques have provided scientists the ability to manipulate desirable traits precisely and quickly. The advancements and breakthroughs in these techniques are making them more efficient and cost effective. In this chapter, we have discussed the application of these approaches in the improvement of key agronomic traits attributed to nutritional quality of staple food crops, oilseed crops, and horticulture plants.

    Silicon supplementation as a promising approach to induce thermotolerance in plants: current understanding and future perspectives
    (Springer Nature Publishing AG, 2023) Bishnoi, Alka; Jangir, Pooja; Shekhawat, Pooja Kanwar; Ram, Hasthi; Soni, Praveen
    In the current situation of climate change, heat is the foremost abiotic stress that is fueling food insecurity by reducing crop production, especially in arid regions around the globe. Therefore, ecofriendly and sustainable solutions are needed to address this challenge. Recent findings have established silicon (Si) as an important stress reliever element in plants which tremendously improves their health under different environmental constraints. Exogenous application of Si via fertigation, foliar spray, or seed priming acts as a booster for the already existing defense machinery of plants to cope with the drastic effects of heat. Si fertigation also improves soil properties including its water holding capacity which indirectly aids to improve plant health. Rhizospheric microorganisms also contribute by increasing the bioavailability of Si in soil. Thus, versatile interactions of Si with soil, plant, and microbes modulate the micro-environment of plants exposed to heat stress which help in mitigating the heat-induced damage to plant growth and fertility. In this review, we focus on the elucidation of the role of Si in heat tolerance at the molecular level. Silicon-derived improvements in various morpho-agronomic, physiological, biochemical, anatomical, and molecular parameters have been discussed in detail. Si-uptake and transport mechanism has been addressed. We have also discussed the knowledge gaps and scope of Si as a biostimulant for future-oriented sustainable agriculture.
