Codon usage in plant genes.
We have examined codon bias in 207 plant gene sequences collected from Genbank and the literature. When this sample was further divided into 53 monocot and 154 dicot genes, the pattern of relative use of synonymous codons was shown to differ between these taxonomic groups, primarily in the use of G + C in the degenerate third base. Maize and soybean codon bias were examined separately and followed the monocot and dicot codon usage patterns respectively. Codon preference in ribulose 1,5 bisphosphate and chlorophyll a/b binding protein, two of the most abundant proteins in leaves was investigated. These highly expressed are more restricted in their codon usage than plant genes in general.
