种子内生菌增强宿主植物重金属抗性的功能机制研究进展

Functional mechanism of seed endophytes enhancing heavy metal resistance of host plants: a review

种子是植物的繁殖器官,其内定殖有一定数量的内生菌,种子内生菌通过垂直传播成为新生植物组织内最早定殖的微生物,对连续几代植物内生菌群落的形成起着决定性作用,并在植物抗逆方面发挥着重要作用。本文对种子内生菌与宿主植物重金属抗性之间的关系及其功能机制进行综述,并对下一步研究方向予以展望。

Seed is the reproductive organ of plants, and there are a certain number of endophytes colonized in the seed. The seed endophytes become the earliest colonized microorganisms in the tissue of new plants through vertical propagation, which plays a decisive role in the formation of endophytic community of successive generations of plants, and plays an important role in plant stress resistance. In this paper, the relationship between seed endophytes and heavy metal resistance of host plants and their functional mechanisms are reviewed, and the future research directions are prospected.
