摘要

Aims This study investigated the role of long-distance signaling in the compositional response of Phaseolus vulgaris rhizomicrobiome to a changing soil environment. Methods P. vulgaris seedlings were grown in Jiangxi and Shaanxi soils under two different planting patterns, 'Mix' (P. vulgaris planted with split roots in two types of soil simultaneously) and 'Double' (P. vulgaris planted with split roots in double pots supplied with the same type of soil type). The rhizomicrobiomes were analyzed by high-throughput sequencing of the bacterial 16S rRNA gene and fungal internal transcribed spacer region. Results There were significant differences in the biotic and abiotic properties between two kinds of soil. The alpha- and beta-diversity of the rhizomicrobiomes were significantly influenced by soil type and planting pattern. Soil type explained the majority of the variation in the rhizomicrobiome composition. The compositional difference between the Jiangxi and Shaanxi rhizomicrobiomes was significantly reduced in the 'Mix' treatment compared with the 'Double' treatment. Conclusions In split-root experiment, the separated roots shared a common aerial part and communicated via long-distance signaling pathways. Hence, this study demonstrated that the long-distance signaling pathways in P. vulgaris regulated and harmonized the rhizomicrobiome composition as the roots sensed two different soil environments.
