大豆bZIP转录因子在生物与非生物胁迫中的作用机制OA

Soybean(Glycine max)has long been recognized as an economically important crop worldwide,and its growth and development were frequently severely restricted by various stress factors.Transcription factors played crucial roles in the molecular networks that regulated soybean response to stresses.Among diverse transcription factor families,the basic leucine zipper(bZIP)family was widely distributed in plants and functions importantly in soybean growth,development,and stress tolerance.Focusing on the soybean bZIP transcription factor family,this paper systematically reviewed its structural characteristics and biological functions,with emphasis on the molecular mechanisms underlying its responses and regulations to biotic stresses such as diseases,as well as abiotic stresses including drought,salt,and low temperature.The indirect regulatory effects of soybean bZIP on yield formation under biotic and abiotic stresses were also discussed.Through comprehensive integration and summary of relevant studies,this review provided theoretical support for clarifying the stress regulatory mechanisms of soybean bZIP transcription factors and laid a solid foundation for the genetic improvement of stress resistance and yield enhancement in soybean.
