植物结瘤素基因响应逆境胁迫的研究进展

Research Progress on the Response of Nodulin Genes in Plants to Biotic and Abiotic Stresses

结瘤素基因最早在豆科植物与根瘤菌互作中发现,负责豆科植物根瘤器官的发生和固氮功能.随后发现结瘤素基因在非豆科植物的抗旱、耐盐、病原菌互作等过程中发挥了重要作用,表明该基因在植物应对生物和非生物胁迫时也具有重要功能.文章就结瘤素基因的分类、在植物应对生物和非生物胁迫时的功能等方面进行综述,以期为结瘤素基因的功能研究提供理论基础,同时为植物抗生物和非生物胁迫基因的挖掘提供新思路.

Nodulin gene was first discovered in the interaction between leguminous plants and rhizobia,which is responsible for the organogenesis and nitrogen fixation of rhizobia in leguminous plants.Subsequently,it was found that the nodulin genes played an important role in drought resistance,salt tolerance and pathogen interaction in non-leguminous plants,indicating that the genes also played a significant role in plants to biotic and abiotic stresses.In this paper,the classification of nodulin genes and their functions in plants under biotic and abiotic stresses were reviewed,which will provide a theoretical basis for the functional research of nodulin genes and recommend new ideas for the exploration of biotic and abiotic stress-resistant genes in plants.
