Mdpi Ag Physiological and Molecular Mechanisms of Plant Resistance to Abiotic Stress

Abiotic stresses-including saline-alkaline conditions, extreme temperatures, water extremes (drought and flooding), and heavy metal toxicity-pose significant threats to crop quality and yield. Through long-term evolution, plants have developed sophisticated stress resistance mechanisms to cope with adverse environments. Elucidating the physiological and molecular foundations of abiotic stress responses is therefore essential for enhancing crop sustainability and addressing the growing global demand for food.This Reprint focuses on the regulatory mechanisms underlying abiotic stress responses in economically important plants, encompassing food crops, horticultural crops, oil crops, and ornamental crops. Studies investigating transcriptional regulatory pathways, splicing factor functions, or root development under stress conditions are included. This aims to help readers broaden their understanding of abiotic stress.
