| 摘 要： | 植物内生菌由于其独特的生态学地位而广受关注,近年来有关植物内生菌与宿主相互作用的研究取得了很大进展.本文综述了植物内生菌通过分泌促生物质、拮抗病原菌等实现与宿主共生互作,同时植物为内生菌提供适宜的黏附表面,使其形成以生物薄膜(biofilm)为主要形式的多细胞聚集体结构以更好地适应周围的生存环境,从而更加高效地对植物产生促生作用.本文论述了内生菌在与植物的互作中形成的多细胞聚集结构在抵抗非生物胁迫方面的独特生理及生态学意义,结合水稻内生成团泛菌YS19形成多细胞聚集体symplasmata现象及其生物学效应,对未来有关植物内生菌的研究方向提出了一些看法.

| Abstract: | Recently, plant endophytes attract much attention due to their special ecological significance. Here reviewed is the recent research advances in plant-endophyte interaction. Specifically, we mainly focused on the beneficial effect of endophytes realized by growth-promoting and production of pathogen resistant substances. We also reviewed one of the recently concerned areas that endophytes obtain high adaptabilities by forming biofilms on the tissue surfaces of their host plants. Finally, using symplasmata formed by rice endophyte Pantoea agglomerans YS19 as an example, the physiological and ecological significance of these multicellular aggregations and their researching future were discussed. |
