Differential responses of root and leaf-associated microbiota to continuous monocultures.

ABSTRACT: Continuous monocultures alter the composition and function of root-associated microbiota, and thus compromise crop health and productivity. In comparison, little is known about how leaf-associated microbiota respond to continuous monocultures. Here, we profiled root and leaf-associated microbiota of peanut plants under monocropping and rotation conditions. Additionally, their protective effects against root pathogen Fusarium oxysporum and leaf pathogen Alternaria alstroemeriae were evaluated. We found that monocropping increased root and leaf disease severity. Meanwhile, the peanut growth and productivity were inhibited by monocropping. Microbiota analysis revealed that monocropping reduced rhizosphere microbial population and diversity, while increased leaf epiphytic microbial population
