Root exudates and rhizosphere microorganisms of Juglans mandshurica in mixed stands of Juglans mandshurica and Larix gmelinii versus pure Juglans mandshurica stands

All samples are set with biological replicates, and the data is complete and traceable. The data on root exudates of Juglans mandshurica was determined using UHPLC-Q Exactive ultra-high performance liquid chromatography-mass spectrometry system. A total of 1632 metabolites were identified, distinguishing between pure forest and mixed forest metabolites (105 unique to pure forest and 76 unique to mixed forest); Record the relative content of key differential metabolites such as indole-3-acetic acid, S-adenosyl-homocysteine, coumarin C, and benzylglucosinolate; Contains KEGG functional annotations, pathway enrichment results, OPLS-DA discriminant analysis, and random forest model analysis data to clarify the differences in secretion metabolic pathways between two types of forest stands.

The rhizosphere microbial community data comes from high-throughput sequencing raw data, including fungal ITS1 region and bacterial 16S rDNA V4 region valid sequences. The raw data has been uploaded to the NCBI SRA database (bacteria: PRJNA1292432; Fungi: PRJNA1292448); Diversity data includes alpha diversity indicators such as fungal and bacterial Ace index, Chao index, Shannon even index, Simpson even index, as well as beta diversity (PCoA) analysis results based on Bray Curtis distance; Community composition data includes relative abundance of species at the phylum level; Functional and network data include relative abundance of fungal and bacterial functional groups, co-occurrence of microbial network nodes, number of connections, modularity, and other characteristic parameters.
