soil metagenome
These sequences represent the cbbL gene (encoding ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit, form I) amplified from soil samples under sand-fixation plantations in the Horqin Sandy Land, Inner Mongolia, China. Samples were collected from four successional stages (shifting sand, early, middle, and late herbaceous communities). The cbbL gene fragments (approximately 380 bp) were amplified using primers K2F and Y2R and sequenced on the Illumina MiSeq platform. This study aimed to characterize the autotrophic bacterial community involved in CO2 fixation via the Calvin-Benson-Bassham cycle during vegetation succession. The sequences contribute to understanding the ecological role of carbon-fixing bacteria in desert ecosystem restoration.
