Abstract

To compare the rhizosphere communities under Masson pine trees with different carbon sequestration abilities, we sampled three families of Masson pine that showed significant differences in their carbon sequestration ability and conducted high-throughput sequencing of the 16S rRNA and ITS in the corresponding soil samples. The diversity of rhizosphere soil microorganisms, the patterns of differences in relative abundance among the different samples and the responses of microorganisms to environmental factors were analyzed. There was no significant difference in the diversity of soil bacteria or fungi among the different samples from Masson pine families with different carbon sequestration abilities, but with the increase in carbon sequestration, the dominant phyla of bacteria and fungi changed. The dominant phylum of soil bacteria changed from Proteobacteria to Acidobacteria, and that of fungi changed from Ascomycota to Basidiomycota. In addition, we investigated the core microbial communities at the genus level among the different samples, and a significant portion of the core genera were involved in carbon metabolism. The microbial communities were greatly influenced by environmental factors such as soil carbon content, soil moisture and altitude. Soil fungi were more sensitive than soil fungi to the rhizosphere activity of Masson pine.
