Abstract
Beneficial interactions between plants and rhizosphere microorganisms are key determinants of plant health with the potential to enhance the sustainability of agricultural practices. However, pinpointing the mechanisms that determine plant disease protection is often difficult due to the complexity of microbial and plant-microbe interactions and their links with the plant’s own defense systems. Here we reported a microbial ecology work which aiming at deciphering the features of microbial communities in natural disease suppressive soils. Besides, we also explored the potential roles of soil microbiome in disease suppression triggered by agricultural managements at both greenhouse and field experiment level, such as resistant variety cropping, soil fumigation and microbial inoculants application. We found several indigenous beneficial taxa may be important components in determining soil suppressiveness against banana Fusarium wilt disease mainly induced by applied microbial inoculants or specific root exudates. Furthermore, our work specially opens up new avenues for improving plant health, in which both plant and associated microbial properties are considered.
