The grape genome is relatively small (approximately 500Mbp) making it an attractive target for genomics. The grape genome is thus similar in size to the rice genome but is composed of a larger number of small chromosomes amenable to physical mapping. Grapes are a woody perennial and thus differ from other species that have been analyzed in detail. We have sequenced cDNA libraries from vegetative tissues and fruits to generate an EST database. Analysis of the first 5000 sequences (2500 from each library) indicated that most ESTs obtained have homology to known genes. The clones had homology to plant genes (68%) and to genes from other organisms (14%). Approximately 18% did not show homology to any sequence of known function in the databases. The two libraries had 275 genes in common. Redundancy was 42% in the leaf library and 39% in the berry library. Functional analysis may identify genes controlling many unique traits in this.
