soil and root metagenome
Samples were collected from a site in the Mu Us Sandy Land (MUSL) in Yanchi, Ningxia, China. Sampling was conducted at the end of October 2022 across three different vegetation successional stages in MUSL: moving dunes (C), semi-fixed dunes (SS), and fixed dunes (FS). A five-point sampling strategy was utilized to collect root endosphere (O) samples (diameter < 2 mm), rhizosphere soil (R), and non-rhizosphere soil (F) from A. ordosica plants at a depth of 30 cm.
