Metagenome analysis of Citrus sinensis rhizosphere infected with Candidatus liberibacter asiaticus reveals distinct structure in bacterial communities.

ABSTRACT: The rhizosphere microbiome plays crucial roles in different root-associated biological functions, especially regulating plant defense systems. Huanglongbing (HLB) disease, caused by Candidatus Liberibacter species, is a disaster threat to the global citrus industry. This study investigates changes in rhizosphere bacterial communities of Citrus sinensis trees infected by Candidatus Liberibacter asiaticus (CLas). We performed the high-throughput sequencing of the rhizosphere-associated bacterial metagenome and identified taxonomic profiles. Alpha diversity based on Shannon and Chao1 indices, and beta diversity based on Bray-Curtis dissimilarity and the UniFrac indices, revealed significant differences in the composition and structure of the rhizosphere microbiome between CLas-infected and CL
