Genome -wide comparisons of MYB and MADS transcriptional factor on codon bias are made in Arabidopsis and Rice. The results obtained by using the structure and phylogenetics analysis of both the transcription factors will be helpful to investigate their interaction between different genes and gene expression and regulation, and also will be potential in the crop breeding.1. The reaching developmant of transcription factors in plantThe inducing genes are controlled mainly by transcription factors at the tran...
