Peach Transcriptome Map
As an effort to develop an extensive Prunus EST database for identification and cloning of genes important to fruit and tree development, 9984 high-quality expressed sequence tags (ESTs) from a peach cDNA library of developing fruit mesocarp. After assembly and annotation, a putative peach unigene set consisting of 3842 ESTs was defined. Using core markers from the general Prunus genetic map, BAC clones are anchored on the genetic map, providing a framework for the construction of a transcript map. A transcript map was developed by hybridizing 1,236 ESTs from the putative peach unigene set. ESTs are anchored to genetic maps when they are hybridized to BACs that have previously been hybridized to genetic markers. ESTs are also anchored to genetic maps when the EST-hybridizing BACs belong to a BAC contig that contains genetically anchored BACs.
