The circadian clock ticks in plant stress responses

Abstract The circadian clock, a time-keeping mechanism, drives nearly 24-h self-sustaining rhythms at the physiological, cellular, and molecular levels, keeping them synchronized with cyclic changes of environmental signals. plant clock is sensitive to external internal stress signals that act as timing cues influence through input pathways system. In order cope stresses, many core oscillators are involved in defense while maintaining daily growth various ways. Recent studies have shown hierarchical multi-oscillator network orchestrates rhythmic accumulation gene transcripts, alternative splicing mRNA precursors, modification turnover proteins, subcellular localization, stimuli-induced phase separation, long-distance transport proteins. This review summarizes essential role response stresses Arabidopsis thaliana crops, including seasonal abiotic (low or high temperature, drought, salinity, nutrition deficiency) biotic (pathogens herbivorous insects). By integrating mechanisms, resistance, we provide temporal perspective for scientists better understand adaptation breed high-quality crop germplasm agricultural production.
