The Citrus Genome Database (CGD) is a comprehensive and innovative resource dedicated to advancing research in citrus genetics, funded by the USDA and NSF. Developed by the MainLab at Washington State University using the open-source Tripal database platform, CGD serves as a crucial repository of genomics and breeding data for various citrus species and their associated organisms, particularly those linked to Huanglongbing (HLB).

The database emerged from collaborative discussions among scientists, breeders, and bioinformaticians aiming to streamline the wealth of existing genetic research into a practical format for breeding programs. CGD facilitates important functionalities including data organization, analysis, and access to a broad range of research tools and datasets. It supports ongoing efforts through various USDA and NSF grants, emphasizing the need for organized genetic information to enhance citrus breeding initiatives. In addition to its core functionalities, CGD also provides resources like expression heatmaps, genomic maps, and publication tools, establishing itself as a pivotal asset in the field of citrus research.
