The rhizomicrobial community is influenced by plant genotype. However, the potential differences in the co-assembly of bacterial and fungal communities between parental lines and different generations of rice progenies have not been examined. Here we compared the bacterial and fungal communities in the rhizomicrobiomes of female parent wild rice; male parent cultivated rice; their F1 progeny; and the F2, F3 and F4 self-crossing generations. Our results showed that the bacterial and fungal α-diversities of the hybrid F1 and self-crossing generations (F2, F3, F4) were closer to one of the two parental lines, which may indicate a role of the parental line in the diversity of the rhizosphere microbial community assembly. Self-crossing from F1 to F4 led to weak co-variation of the bacterial and fungal communities and distinct rhizosphere microbiomes. In the parental and self-crossing progenies, the reduction of community dissimilarity was higher for the fungal community than for the bacterial community.
根际微生物群落受植物基因型影响。然而，尚未研究亲本系与不同世代水稻后代之间细菌和真菌群落共组装的潜在差异。在此，我们比较了野生稻母本、栽培稻父本、它们的F1后代以及F2、F3和F4自交世代根际微生物群中的细菌和真菌群落。我们的结果表明，杂交F1代和自交世代（F2、F3、F4）的细菌和真菌α多样性更接近两个亲本系之一，这可能表明亲本系在根际微生物群落组装的多样性中发挥作用。从F1到F4的自交导致细菌和真菌群落的弱共变以及不同的根际微生物群。在亲本和自交后代中，真菌群落的群落差异减少幅度高于细菌群落。
