About MapleOmics

NEW Comparative genomics data for 11 Acer and 2 Dipteronia species, plus a Citrus outgroup · BLAST covers 14 nuclear genomes
MapleOmics is a multi-omics database for maple trees (Acer spp.), built for comparative and functional genomics research. The platform integrates genome sequences, gene annotations, transcriptomics, proteomics, and epigenomics across 11 Acer species and 2 Dipteronia species, with Citrus sinensis as the outgroup.

The database provides interactive tools for gene expression visualization, protein–protein interaction network analysis, epigenome exploration, and BLAST sequence similarity searching, supporting pan-genome and comparative genomics studies of the maple family (Sapindaceae).

Developed by Jiangsu Academy of Agricultural Sciences (JAAS), Nanjing, China. Project No. X101SC21071805
