About

Abiotic stress such as drought, salinity, elevated ozone, cold and heat, long-term scant sunlight, and combinations of these stresses have adverse effects on crop productivity. Changing environments due to global warming exacerbate the negative effects of abiotic stress on crop production and threaten food security worldwide. Moreover, crops are routinely subjected to a combination of varying abiotic stresses in the field, leading to an even greater loss of crop productivity. Abiotic stress influences many aspects of crop physiology including non-adaptive and adaptive responses and causes widespread changes in cellular processes. Therefore, understanding the physiological responses of crops to adverse environmental conditions is critical for global food security.

Extensive studies in the last decade have gradually revealed the mechanisms of how plants cope with abiotic stress, yet many aspects remain unknown, especially for crops subject to combined abiotic stresses. Further understanding of crop physiological responses and the identification of potential unknown stress-responsive pathways to (combined) abiotic stress will contribute to a better understanding of underlying physiological mechanisms.

This Research Topic aims to incorporate contributions from leading plant scientists focused on collecting studies on the physiological responses of various crops to numerous abiotic stresses and their combinations. We invite authors to submit original research, reviews/mini-reviews, meta-analysis articles related to, but not limited to, the following topics:

• Responses of crops to abiotic stresses from leaf to whole plant level
• Plant physiological responses to abiotic stresses
• Interactive effects of abiotic stress on crop physiology and productivity
• Crop physiological responses to short-term and long-term abiotic stresses
• Differences in crop responses to abiotic stresses during the different crop growth stages
