植物转录因子在线虫与寄主互作中的功能研究进展

Advances in the function of plant transcription factors in nematode-host interactions

植物在生长过程中经常受到真菌、细菌、病毒和线虫等生物胁迫。转录因子是一类能够与目的基因特异结合并进行转录调控的蛋白质,在植物响应生物胁迫过程中具有重要作用。在线虫与植物互作过程中,植物的转录因子通过调控其靶标基因的表达对线虫侵入作出响应。本文对根结线虫和孢囊线虫的发生和危害、植物转录因子的结构和功能以及其在线虫与寄主互作中的功能进行综述,并对响应线虫侵染的植物转录因子的鉴定及前沿研究进行探讨,以期为深入开展线虫与寄主植物互作机制提供参考。

Plants are commonly injured by biotic stresses,such as infections from fungi,bacteria,viruses,and nematodes during the growing season.Plant transcription factors are proteins that bind to DNA and regulate gene expression,playing a crucial role in the transcriptional response to biotic stress.During nematode-host interactions,plant transcription factors respond to nematode infestation by regulating the expression of their target genes.This review discusses the occurrence and damage caused by root-knot nematodes and cyst nematodes,the structure and function of plant transcription factors,and their functions in nematode-host interactions.It also covers methods for exploring plant transcription factors responding to nematode infection and recent achievements in this field.The review provides a reference for further research into the interaction mechanisms between nematodes and host plants.
