ocsESTdb

ocsESTdb is a bioinformatics resource focusing on gene transcription of oil crops from a comparative perspective. The first database contains expressed sequence tag (EST) information on seeds of four large-scale oil crops, including rapeseed, soybean, sesame, and peanut. The database includes 248,522 ESTs and 106,835 unigenes collected from the cDNA libraries of the four crops. These unigenes were annotated by searching them against databases including TAIR, NR protein database, Gene Ontology, COG, Swiss-Prot, TrEMBL, and Kyoto Encyclopedia of Genes and Genomes (KEGG).

The database also includes five genome-scale metabolic networks that contain different numbers of metabolites and gene-enzyme reaction-association entries. The metabolic networks were analyzed and constructed using Cytoscape and yEd programs. ocsESTdb provides details of unigene entries, deduced amino acid sequences, putative annotation, and intuitive and graphical representations of EST/unigene sequences, functional annotations, metabolic pathways, and metabolic networks.
