Abstract
As sessile organisms, plants have evolved elaborate epigenetic regulatory networks to adapt to a wide range of abiotic stress. Chromatin remodelling is a core epigenetic regulatory mechanism that refers to the process by which chromatin remodelling complexes mediate dynamic changes in chromatin spatial conformation and DNA accessibility through nucleosome sliding, histone variant exchange, nucleosome eviction, or spacing adjustment. The flexible and reversible modifications of chromatin structure enable plants to rapidly respond to external stimuli, thereby safeguarding their survival and promoting adaptive plasticity. This review summarises the research progress on chromatin remodelling complexes and their regulatory mechanisms in plant environmental adaptation. Furthermore, we discuss the current challenges and future research directions in this field, including the need to decipher the recruitment specificity of chromatin remodellers, investigate their coordination networks under combined abiotic stresses, and translate mechanistic insights into epigenetic engineering for crop improvement. Collectively, this review aims to provide a comprehensive overview of chromatin remodelling-mediated stress adaptation and lay a foundation for developing stress-tolerant crop varieties via epigenetic engineering.
