Role of Serendipita indica in enhancing drought tolerance in crops
(Elsevier B.V., 2021) Jangir, Pooja; Shekhawat, Pooja Kanwar; Bishnoi, Alka; Ram, Hasthi; Soni, Praveen
The root endophytic fungus Serendipita indica (S. indica) acts as a bio-fertilizer, immuno-modulator, stress-buster and enhances plant growth, and protects the host plant from various biotic and abiotic stresses. Recent high-throughput omics approaches have helped in understanding the role of S. indica in host plants under stress conditions. The present review focuses on the mechanism of S. indica mediated drought-tolerance in crops by analyzing morphological, physiological, biochemical, and molecular processes. Interactions of S. indica with other plant growth-promoting microorganisms have been discussed. The knowledge gap and future prospects have been pointed out.
Serendipita indica: Harnessing its versatile potential for food and nutritional security
(Elsevier B.V., 2021) Shekhawat, Pooja Kanwar; Jangir, Pooja; Bishnoi, Alka; Roy, Shweta; Ram, Hasthi; Soni, Praveen
Quantity as well as quality of food is a major concern for increasing human population. Serendipita indica, a root endophytic fungus, has multifarious applications in agriculture. It increases nutrient and water uptake, carbon assimilation efficiency and stress-resistance which in turn enhances the growth and yield of plants. Moreover, it improves contents of minerals, fatty acids and essential oil, composition of oil, and fruit firmness in different plants. It also enhances the production of secondary metabolites having medicinal properties. This review highlights the role of Serendipita indica in increasing crop production and improving food quality. The underlying mechanism has also been illustrated.
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.
