Editorial: Heat stress: response, mitigation, and tolerance in plants

Abstract

Heat stress is one of the major problems affecting the growth and yield of most of the agriculturally important crops. It causes oxidative bursts inside the cells, damaging the cell organelles, membranes, and leads to the denaturation/aggregation of enzymes (Kumar et al., 2023). In order to cope with the fluctuation in temperature, plants have developed various mechanisms like the expression of signalling molecules (like MAPK, CDPK, etc.), antioxidant enzymes (SOD, CAT, GPx, etc.), Heat shock transcription factors (TaHSFA6e, HSF3, etc.), heat shock proteins (sHSPs like HSP17, HSP26, etc.) and many other stressassociated genes like pyrrolyl disulphide isomerase, ABC-Transporter, universal stress proteins, etc. (Azameti et al., 2022).This Research Topic has been meticulously organized, featuring thirteen original research articles that have been divided into two broad areas to emphasize the findings in the best possible manner: (1) Response of plants to stress/secondary metabolites or hormones, and (2) Omics approaches for the identification of stress-associated genes and proteins.

Nano-Food Farming Approaches to Mitigate Heat Stress under Ongoing Climate Change: A Review

“…Agroecosystems are vital to our modern societies and the global environment [106,107]. Each component of the agroecosystem is affected by climate change and heat stress, including soil [7,108], water [50], microbes [109], plants [110][111][112], animals [113], and humans [114][115][116] (Figure 5; [48,109,110]). As examples, these impacts may involve changes in crop phenology, soil moisture content, soil carbon pools, and vegetation respiration, among others.…”
