An astonishing increase in temperature is posing several harmful impacts on crop plants. Heat stress is an abiotic environmental phenomenon that causes limits, inhibits plant growth, metabolism, and productivity worldwide, resulting in losses in production yields. Heat stress is caused by human activities and global warming,s such as greenhouse gases, carbon dioxide, methane, nitrous oxide, and water vapour. There are many pieces of evidence to support that heat stress reduces the crop plants yield worldwide, and the effects of heat stress are challenging to meet nutritional security and global food security for human beings. Heat stress has negative impacts on each developmental stage, including from germination to harvesting. Prevalent approaches for heat adaption is inadequate management that is unable either to increase the crop productivity or sustain ld. Several responses to dissect the relevant knowledge about heat stress mechanism involving morphological phenomena, physiological phenomena, reproductive replies, and molecular responses such as heat shock proteins act as mRNA synthesis, mRNA control (effects of genes during heat stress), the translation process, heat response element. There are such phenomena involving disseminating the knowledge concerning heat stress. In this review, we summarise the effect of heat stress on plant mechanisms, including morphological, biochemical and molecular responses.

“…Reproductive stages of grain legumes that are adapted to cold environment, such as chickpea, lentil, pea and faba bean, face warmer conditions under late‐sown condition, which results in substantial reduction in seed setting and seed weight (Gaur et al., ; Jha, Chaturvedi et al., ; Saxena, Saxena, & Mohammed, ; Siddique, Jettner, Regan, & Loss, ). The serious impacts of the HS in staple crops such as rice (Manigbas & Sebastian, ; Tian, Tao, Jing, Zhang, & Tao, ), wheat (Easterling et al., ; You, Rosegrant, Wood, & Sun, ), maize (Deryng et al., ; Lobell & Field, ; Lobell et al., ) have been thoroughly reviewed by various researchers (Barnabas, Jager, & Feher, ; Bita & Gerats, ; Hasanuzzaman, Nahar, Alam, Roychowdhury, & Fujita, ; Jha, Bohra, & Singh, ; Kaushal, Bhandari, Siddique, & Nayyar, ). Like cereal crops, HS in grain legumes is reported to create impairments in key physiological pathways, viz.…”

Integrated “omics” approaches to sustain global productivity of major grain legumes under heat stress

Grain legumes serve as key sources of dietary protein to the global human population. Consequence of high-temperature (HT) stress is increasingly evident as drastically lost production of different crops including grain legumes worldwide, thus putting the global food security under great threat. In a changing climate scenario, cool season-adapted grain legumes frequently encounter heat stress (HS) during their reproductive phase, thus witnessing serious yield losses. To combat the emerging challenges of HT stress, an integrated approach demanding collaborative efforts from various disciplines of plant science should be in place. This review summarizes major impacts of HT stress on grain legume, and captures the relevance of crop genetic resources to HS tolerance in these crops. Measurement of physiological traits assumes key place in view of ever-increasing precision of next-generation phenotyping assays. We also discuss the significance of genetic inheritance and QTL discovery and evolving "omics" science for developing HS tolerance grain legume crops.
