Abiotic stresses adversely impact plants survival and growth, which in turn affect plants especially crop yields worldwide. To cope with these stresses, plant responses depend on the activation of molecular networks cascades, including stress perception, signal transduction, and the expression of specific stress-related genes. Plant bZIP (basic leucine zipper) transcription factors are important regulators that respond to diverse abiotic stresses.By binding to specific cis-elements, bZIPs can control the transcription of target genes, giving plants stress resistance. This review describes the structural characteristics of bZIPs and summarizes recent progress in analyzing the molecular mechanisms regulating plant responses to salinity, drought, and cold in different plant species. The main goal is to deepen the understanding of bZIPs and explore their value in genetic improvement of plants.
非生物胁迫对植物的存活和生长产生不利影响，进而影响全球范围内的植物尤其是作物产量。为应对这些胁迫，植物的反应依赖于分子网络级联反应的激活，包括胁迫感知、信号转导以及特定胁迫相关基因的表达。植物bZIP（碱性亮氨酸拉链）转录因子是应对多种非生物胁迫的重要调节因子。通过与特定顺式元件结合，bZIP蛋白可以控制靶基因的转录，赋予植物抗逆性。本文综述了bZIP蛋白的结构特征，并总结了不同植物物种中分析调控植物对盐、干旱和寒冷胁迫反应的分子机制的最新进展。主要目的是加深对bZIP蛋白的理解，并探索它们在植物遗传改良中的价值。
