Mango is a delicious and nutritious fruit widely distributed in tropical and subtropical countries and regions. In China, especially in Baise, mango is one of the most famous fruits because of its tasting. In the local agricultural income, the mango industry occupies an extremely important position. Therefore, the research on mangoes and the prevention and treatment of their root diseases are directly related to the local economic development. More and more studies have shown that microbiota plays an important role in crop plant growth and disease prevention, and contributes to the sustainable development of agriculture in general. This study used high-throughput sequencing technology to study the soil microbial diversity of mango roots in Baise. The results showed that the soil where the roots grow normally and the soil with diseased roots have a certain degree of similarity and differences. The main types of bacterial communities are Proteobacteria, Acidobacteria, Verrucomicrobia, Planctomveetes and Bacteroidetes. Compared with normal soil, the relative abundance of Proteobacteria, Verrucomicrobia and Gemmatimonadetes is low, and the relative abundance of Acidobacteria, Bacteroidetes, Bacteroidota, Planctomveetes and Rookubacteria is high. The analysis of the difference between the Kyoto Encyclopedia of Genes and Genomes (KEGG) metabolic pathways showed that the two groups of samples had a higher abundance ratio and significant differences in functions such as amino acid metabolism, metabolism of cofactors and vitamins (P<0.05). Clusters of Orthologous Groups (COG) analysis results showed that in addition to extracellular structure, RNA processing and modification, and cytoskeleton function, other functions were significantly different in the two samples (P<0.05). These results revealed for the first time the changes in soil microbial diversity between normal and diseased roots of mangoes, and provided a theoretical basis for guiding the healthy planting and biological control of the root diseases of mangoes.
