摘要:

大豆根际具有特定的微生物群落,但不同基因型大豆之间微生物群落结构的差异尚未得到解释。本研究分析了三种基因型大豆根际微生物群落结构。通过多样性和群落结构分析,证明了不同基因型大豆根际微生物群落间的差异,且每种基因型都由特定的根际微生物群落组成。共现网络分析发现,不同基因型大豆具有不同的根际微生物网络,网络中根瘤菌和根际微生物之间的关系在不同基因型的植物宿主之间表现出显著差异。生态功能预测发现,不同基因型的大豆招募了特定功能的根际微生物。研究结果表明,大豆基因型调控了根际微生物群落结构的差异,为大豆微生物菌剂的开发提供了参考和理论支持。

Abstract:

The soybean rhizosphere has a specific microbial community, but the differences in microbial community structure between different soybean genotypes have not been explained.  The present study analyzed the structure of the rhizosphere microbial community in three soybean genotypes.  Differences in rhizosphere microbial communities between different soybean genotypes were verified using diversity testing and community composition, and each genotype had a specific rhizosphere microbial community composition.  Co-occurrence network analysis found that different genotype plant hosts had different rhizosphere microbial networks.  The relationship between rhizobia and rhizosphere microorganisms in the network also exhibited significant differences between different genotype plant hosts.  The ecological function prediction found that different genotypes of soybean recruited the specific rhizosphere microbial community.  These results demonstrated that soybean genotype regulated rhizosphere microbial community structure differences.  The study provides a reference and theoretical support for developing soybean microbial inoculum in the future.
