烟草内生菌资源及其应用研究进展

Biodiversity of endophytes in tobacco plants and their potential application―a mini review

摘要:

烟草内生菌广泛分布于烟草根、茎、叶及种子中，具有丰富的生物多样性。研究发现感染内生菌的烟草往往具有生长迅速、抗病虫害能力强、亚硝胺类物质含量低等优势，总体上具有更强的生存竞争力和更优的品质。本文综述了烟草内生菌资源概况及其在烟草栽培中的重要作用，总结了内生菌作用机制。最后，探讨了当前烟草内生菌应用中存在的问题，并对其应用前景进行了展望。

Abstract:

Endophytes are widely distributed in roots, stems and seeds of tobacco plants. It has been well documented that tobacco plants infected by endophytes are generally more competitive compared with uninfected plants, as indicated by better growth, stronger resistance to diseases and pests, and lower content of nitrosamines. This paper reviewed recent research progresses in biodiversity of endophytes in tobacco plants and their important role in tobacco cultivation, and summarized the functioning mechanisms of endophytes. Finally, the weaknesses in current research were discussed, and research perspectives were also proposed.
