Bacterial Diversities in Rhizosphere Soils at Sites of Healthy and Fusarium Wilt Infected Chili Plants

  •   Objective  Diversities of the bacterial community in the rhizosphere soils, where healthy or fusarium wilt (Fusarium oxysporum Schl.) infected chili plants were found, were compared for information to facilitate the disease control.
      Method  Soil samples at sites of healthy (JK) and diseased (KW) chili plants from 3 cultivation extension stations in Zhangzhou, Fujian were collected. The macrogenomic sequences of the specimens were obtained using Illumina Miseq high-throughput platform.
      Result  The high-quality alpha diversity indices on KW was 14376 fewer and the operational taxonomic units 1239 less than those of JK. The microbial phyla found in JK and KW were similar on composition but significantly differed on relative abundance. Among the various genera identified, Sphingomonas in JK was 5.05% higher than in KW on relative abundance, while Metallibacterium 6.09% lower. The analysis on part of the species indicated that the abundance of 4 genera, such as Solirubrobacter, Microbispora, Catelliglobosispora and Pseudolabrys, were lower in KW than JK.
      Conclusion  The differentiations between JK and KW on the composition and abundance of their microbial communities could likely affect the occurrence of the wilt on the chili plants grown on the sites. Hence, measures for remedy, such as addition of dominant probiotics in the soil at early stage of plant growth, might be a plausible new approach to control the wilt disease on chili plants in the field.
