我国大豆根瘤内生菌资源多样性研究

植物内生菌已成为植物微生态系统中的重要组成部分，根瘤内生菌和根瘤菌普遍共存于特殊的根瘤生 境。比较了根瘤内生菌和根瘤菌与宿主间关系存在的区别，对大豆根瘤内生菌的种类、宿主和适应性、生物固氮、促 进植物生长、增强宿主抗逆、抗病能力以及联合修复环境污染等功能多样性进行论述，指出大豆根瘤内生菌研究的 发展方向，对进一步促进植物生长、发展可持续农业具有重要意义。 ）

Research on resource diversity of soybean Glycine max (L.) Merr nodule endophytes in China

Endophytic bacteria have become an important part of microecosystem, endophytic bacteria and Rhizobia commonly coexist in the special nodule habitat. The relationship differences of endophytic bacteria and Rhizobia in root nodule and host was compared. Combined with group research, the types, the host and the adaptability of soybean nodule endophytes, functional diversity of soybean root nodule endophytes including biological nitrogen fixation, promoting plant growth, enhancing host stress resistance, disease resistance and ability of combined remediation to environmental pollution were summarized. Based on analysis above, author pointed out the research direction of soybean nodule endophytes, to further promote plant growth and develope sustainable agriculture.
