Protein encoding genes in an ancient plant: analysis of codon usage retained genes and splice sites in a moss Physcomitrella patens

摘要

BackgroundThe moss Physcomitrella patens is an emerging plant model system due to its high rate of homologous recombination, haploidy, simple body plan, physiological properties as well as phylogenetic position. Available EST data was clustered and assembled, and provided the basis for a genome-wide analysis of protein encoding genes.
