Development History, Structure, and Function of ASR ( Abscisic Acid-Stress-Ripening ) Transcription Factor

Abiotic and biotic stress factors seriously affect plant growth and development. The process of plant response to abiotic stress involves the synergistic action of multiple resistance genes. The ( ) gene is a plant-specific transcription factor that plays a central role in regulating plant senescence, fruit ripening, and response to abiotic stress. family members are highly conserved in plant evolution and contain ABA/WBS domains. was first identified and characterized in tomatoes ( L.). Subsequently, the gene has been reported in many plant species, extending from gymnosperms to monocots and dicots, but lacks orthologues in ( ). The promoter regions of genes in most species contain light-responsive elements, phytohormone-responsive elements, and abiotic stress-responsive elements. In addition, genes can respond to biotic stresses via regulating the expression of defense genes in various plants. This review comprehensively summarizes the evolutionary history, gene and protein structures, and functions of the gene family members in plant responses to salt stress, low temperature stress, pathogen stress, drought stress, and metal ions, which will provide valuable references for breeding high-yielding and stress-resistant plant varieties.
