Organic Fertilizer Enhances Taro Soft Rot Resistance via Root-Exuded miRNA-Mediated Regulation of the Rhizosphere Microbiota
This study aims to investigate the dynamic changes in microbial communities during taro cultivation and their response to soil-borne diseases. Soil and organic fertilizer samples from different treatments were collected for 16S rRNA sequencing. The samples include: (1) Taro rhizosphere soil before and after inoculation with the pathogen Dickeya fangzhongdai, to analyze the impact of pathogen invasion on the microecology; (2) Soil samples before planting and after harvest, to assess the shaping effect of the planting cycle on microbial diversity; (3) Applied organic fertilizer samples, to determine the potential contribution of exogenous microorganisms to the native soil flora. Comparative analysis aims to reveal microbiological evidence related to the pathogenic mechanism of Dickeya and provide a theoretical basis for the biological control of taro soil-borne diseases.
