Floral gene resources from basal angiosperms for comparative genomics research.

The Floral Genome Project was initiated to bridge the genomic gap between the most broadly studied plant model systems. Arabidopsis and rice, although now completely sequenced and under intensive comparative genomic investigation, are separated by ca. 125 million years of evolutionary time, and cannot in isolation provide a comprehensive perspective on structural and functional aspects of flowering plant genome dynamics. Here we discuss new genomic resources available to the scientific community comprising cDNA libraries and EST sequences for a suite of phylogenetically basal angiosperms specifically selected to bridge the gaps between these model plants and provide insights into gene content and genome structure in the earliest flowering plants. Initial comparisons illustrate the utility of the EST data sets toward discovery of the basic floral transcriptome. These first findings also afford the opportunity to address a number of conspicuous evolutionary genomic questions, including genome-wide duplication history, gene lineage-specific duplication and functional divergence, and analyses of adaptive molecular evolution.
