Community composition in mangrove sediment and abundant potential interactions therein. a Strategy for exploring the potentially abundant interactions in the mangrove sediment. We derived 666 MAGs via the coassembly of the metagenomic sequences from 5 layers of the sediment and combined each two of MAGs to obtain all the possible pairs for which the metabolic interaction potential (MIP) was assessed using SMETANA. The same process was performed for the corresponding transcriptomes of the 666 MAGs. All genomic and transcriptomic pairs with an MIP \(\geqslant 5\) were regarded as potentially high interacting pairs to be included in the following analysis. b The community composition of different layers of sediment is revealed by the relative abundance of phyla; the tendency of the abundance distribution of all the MAGs in sediments from different depths is reflected by the slope of the linear fitting of the normalized abundance of one MAG with the normalized depth. c Genomic and transcriptomic distribution of the MIP scores of all possible pairs of MAGs in the samples. Detailed information on the MAGs, including taxonomic classifications, relative abundance, and transcript abundance, is provided in Table S1. The names of the MAGs consist of the abbreviation (F) of the sampling position (Futian mangrove) and the abbreviation (0) of the year (2020) along with their serial numbers. All of the pairs and the corresponding MIP scores are listed in Table S2. N-depth, normalized depth; N-TPM, normalized TPM
