The plant-microbe interaction can affect ecosystem function, and many studies have demonstrated that plant species influence relevant microorganisms. In this study, microbial communities in bulk soil, rhizosphere soil and phyllosphere from different maize varieties were investigated using high-throughput sequencing method. Results demonstrated that cultivar Gaoneng 1 (G1) showed higher bacterial diversity in soil (both bulk and rhizosphere soils) and lower bacterial diversity in the phyllosphere, while cultivar Gaoneng 2 (G2) had lower fungal diversity in both the soil and phyllosphere compare to the other cultivars. The bacterial community structure of soils among the three varieties was significantly different; however, no significant differences were found in the soil fungal community and phyllosphere bacterial and fungal community. The soil networks from cultivar G1 and phyllosphere networks from cultivar Zhengdan (ZD) have the highest complexity in contrast to the other two cultivars. In conclusion, the bacterial community structure in bulk soil of different cultivars was significantly different, so do the co-occurrence ecological networks of phyllosphere bacterial community. This study comprehensively analyzed the microbial community among different maize cultivars and could be useful for guiding practices, such as evaluation of new plant cultivars and quality predictions of these varieties at the microbial level.
植物-微生物相互作用会影响生态系统功能，许多研究表明，植物物种会影响相关微生物。在这项研究中，采用高通量测序方法研究了不同玉米品种的土壤、根际和叶际的微生物群落。结果表明，与其他品种相比，品种 Gaoneng 1（G1）在土壤（包括根际和非根际土壤）中的细菌多样性较高，而在叶际的细菌多样性较低；品种 Gaoneng 2（G2）在土壤和叶际中的真菌多样性均较低。三种品种的土壤细菌群落结构差异显著；然而，土壤真菌群落和叶际细菌和真菌群落没有显著差异。与其他两个品种相比，品种 G1 的土壤网络和品种 Zhengdan（ZD）的叶际网络具有最高的复杂性。总之，不同品种的非根际土壤细菌群落结构存在显著差异，叶际细菌群落的共生生态网络也是如此。本研究全面分析了不同玉米品种的微生物群落，可为新植物品种的评估以及从微生物水平预测这些品种的质量提供指导。
