Abstract Background Plants have evolved multiple strategies to cope with the ever-changing external environment.

Autophagy positively regulates expression anthocyanin biosynthesis-related genes, thereby influencing accumulation Arabidopsis low-temperature Moreover, found directly suppresses autophagy-related genes reduces autophagic flux. The RNA-seq data revealed cold-responsive were pre-activated mutant atg13ab even before treatment. Additionally, observed constitutive dehydrin protein COR47 atg13ab. Conclusions Taken together, these suggest is negative regulator Arabidopsis.

Abstract As sessile organisms, plants are inevitably threatened by various abiotic stresses. Abiotic stresses seriously affect plant growth and development crop yield. Plants have evolved complex regulatory networks to resist that occur during their life cycle. The hormone abscisic acid (ABA) is accumulated under osmotic stress conditions such as drought, salt, others. ABA signaling pathway plays a key role in response stresses, which ABA‐responsive element binding factors (ABFs) play crucial the whole process. ABFs class of basic leucine zipper proteins (bZIPs) specifically recognize elements belong subfamily bZIP family. discoveries ABFs‐mediated tolerance multiple including salinity, cold, heat highlighted discussed this review. aim review further analyze mechanisms regulation mediated lay foundation for breeding superior stress‐resistant varieties.
