| Abstract: | In order to understand the composition and influencing factors of broad-spectrum pathogenic microorganisms in soil and root (rhizosphere and rhizoplane) of rubber plantations, metagenome sequencing was used to analyze the composition and influencing factors of pathogenic microorganisms in soil, rhizosphere and rhizoplane of healthy rubber plantations in Hainan (Danzhou, Wanning and Ledong) and Xishuangbanna (Jinghong, Menglun and Mengman). The results showed that plant pathogenic microorganisms belonged to Proteobacteria, Actinobacteria and Ascomycota at the phylum level, and to Pseudomonas, Ralstonia, Burkholderia, Streptomyces, Agrobacterium, Xanthomonas, Pantoea, Clavibacter, Pectobacterium and Xylella at the genus level with Ascomycota as the main pathogen at the genus level. There was no significant difference in pathogenic microorganisms in the rhizospheres between the rubber plantations in Hainan and Xishuangbanna. The composition of pathogenic microorganisms was similar in the soil and rhizosphere samples, and similar in the rhizoplane samples. There was a significant positive correlation between NH4-N and pathogenic microorganisms. In conclusion there was no significant difference in pathogenic microorganisms in soil, rhizosphere and rhizoplane between the rubber plantations in Hainan and Xishuangbanna. A significant positive correlation was observed between pathogenic microorganisms and NH4-N, and that the composition of pathogenic microorganisms was related to the exudates of the rhizoplane. |
