Comprehensive genomics platform for cotton, integrating 18 high-quality genome assemblies from 14 Gossypium species, along with genome annotations, variation data (SNPs and INDELs), and four transcriptomes. It provides a suite of online tools for gene search, BLAST and BLAT sequence alignment, orthologous gene ID lookup, co-expression network analysis, primer design, and genome browsing via GBrowse and JBrowse. Users can also visualize expression profiles, draw heatmaps, and access functional annotations from KEGG, GO, and other databases. All data are freely available for download. GRAND aims to support cotton breeding and functional genomics by making multi-omics data easily accessible and analyzable.
