Welcome to the Citrus Genome Database

Funded through the USDA NIFA National Research Support Project, NRSP10 from 2014 to 2019 and the USDA NIFA Specialty Crop Research Initiative project, tree fruit Genome Database Resources (tfGDR, 2009-2014), the Citrus Genome Database houses the genomics, genetics and breeding data for sweet orange, trifoliate orange, grapefruit, mandarin, tangerine, pummelo, lemon, lime and other related species from the Citrus family. In citrus, the fundamental genomic tools include linkage maps, BAC libraries, physical maps, EST libraries, microarray platforms, and whole genome sequencing of sweet orange (heterozygous diploid) and mandarin (haploid). To facilitate efficient application in molecular breeding programs we will integrate large scale sequences, genetic markers and trait loci with diversity data, assign controlled vocabularies to the datasets and develop breeder interface tools. In collaboration with the Citrus community, this database is housed at at Washington State University (Dorrie Main), with support from the University of Florida (Fred Gmitter), Clemson University (Albert Abbott) and the Boyce Thompson Institute for Plant Research (Lukas Mueller).

Updates will be made available via this website, to keep informed check back regularly or join Citrus Genome Database mailing list. If you have any questions, feedback or problems, please contact us through the contact link on the navigation bar.
