Abstract
Numerous studies highlight rhizobacteria’s significance for plant health. This study investigated rhizosphere bacterial communities of three tobacco varieties in Qingshui (QS) and Dahu (DH), Fujian, China,using 16S rDNA amplicon sequencing. Results showed significant alpha diversity differences of rhizosphere bacteria between QS and DH, while tobacco genotype had no effect on alpha diversity in both sites. Neither cultivation sites nor varieties affected beta diversity or bacterial community structure. Dominant phyla were Proteobacteria and Acidobacteria; major genera included uncharacterized Proteobacteria, Candidatus Nitrosopelagicus, and Stenotrophomonas. Community structure was influenced by climate and soil nutrients, with environmental factors impacting more than host genotype. This study improves understanding of tobacco rhizosphere bacteria, aiding plant growth control and tobacco quality enhancement.
