Welcome to TCOD!

TCOD, is a comprehensive multi-omics data platform for tropical crops, provides data service for selective breeding and trait improvement research of tropical crops. It serves as a valuable resource by integrating a wide range of data, including genes, genomes, variants, expressions, and cultivars. In addition, TCOD provides a series of online tools for data mining and visualization to facilitate cross-species investigations.
