The enormous degree of morphological diversity of flowers has held the fascination of scientists for centuries. Around 200 genes have been previously identified with roles in flower initiation and development, including the five classes of genes (A-B-C-D-E model) that are responsible for the specification of floral organ identity in a combinatory manner. Duplication and diversification within these floral genes might have been key processes in flower evolution. Using sequence data from sequenced plant genomes, including data from a preliminary genome assembly and annotation of the basalmost angiosperm, Amborella trichopoda, we traced the origin of floral genes in sequenced plant lineages, and then performed genomic analysis of the evolutionary history of each gene. This may help to provide better understanding of the origin, development and diversification of flowers and flowering plants.
