bZIP转录因子在植物逆境胁迫响应和生长发育中的作用
Roles of bZIP Transcription Factor in the Response to Stresses,and Growth and Development in Plants
摘要
Abstract
bZIP,one of the largest transcription factor families in plants,plays an important role in the response to stress and growth and development of plants.It has a conserved domain consisting of about 60-80 amino acids,including a highly conserved alkaline region and a relatively variable leucine zipper region.bZIP regulates the expressions of target genes by specifically binding to DNA sequences containing ACGT cores in target gene promoters in homologous or heterodimeric forms.When plants are stimulated by stress signals,bZIP is phosphorylated by the upstream signal-responsive kinases,and its stability is enhanced through phosphorylation.Under stresses(such as drought,salt,temperature,light,heavy metal,and plant disease)conditions,bZIP binds to the promoter regions of stress-related genes and interacts with other proteins to promote or inhibit the expressions of these genes,thus positively or negatively regulating the responses to abiotic stress and biotic stress.In addition,bZIP is involved in the synthesis and metabolism of many substances(such as anthocyanins,terpenes,flavonoids,and alkaloids)during plant growth and development,and also mediates the regulation of hormones(such as abscisic acid,salicylic acid,and jasmonic acid)signaling pathways.In this paper,the discovery,structure,classification,regulation of the bZIP transcription factors and their roles in plant stress response and growth and development are reviewed,and the future research directions are also prospected.This paper may provide theoretical basis and technical support for genetic improvement of crops stress resistance.关键词
