In nature, plants are exposed to an ever-changing environment with increasing frequencies of multiple abiotic stresses. These stresses act either in combination or sequentially, thereby driving vegetation dynamics and limiting plant growth productivity worldwide. Plants' responses against these combined sequential clearly differ from that triggered by individual stress. Until now, experimental studies were mainly focused on stress, but have overlooked the complex stress response generated stresses, as well their interaction each other. However, recent demonstrated overlap respect central nodes interacting signaling pathways, impact cannot be modelled swimming extreme event. Taken together, deciphering regulatory networks operative between various agronomically important crops will contribute towards designing strategies for development tolerance combinations. This review provides a brief overview developments interactive effects sequentially occurring crop plants. We believe this study may improve our understanding molecular physiological mechanisms untangling plants, also provide promising venue agronomists, physiologists, biologists.

Reproductive-stage heat stress (RSHS) poses a major constraint to cereal crop production by damaging main plant reproductive structures and hampering processes, including pollen stigma viability, pollination, fertilization, grain setting filling. Despite this well-recognized fact, research on (HS) is relatively recent compared other abiotic stresses, such as drought salinity, in particular, RSHS studies cereals are considerably few comparison with seedling-stage vegetative-stage-centered studies. Meanwhile, climate change-exacerbated HS, independently or synergistically drought, will have huge implications performance future global food security. Fortunately, due their sedentary nature, plants evolved complex diverse transient long-term mechanisms perceive, transduce, respond adapt HS at the molecular, cell, physiological whole levels. Therefore, uncovering molecular governing response tolerance facilitates designing of effective strategies improve crops. In review, we update our understanding several aspects cereals, particularly impacts processes yield; signal perception transduction; transcriptional regulation shock factors stress-responsive genes.
