Genome-Wide Comparative Analysis of BZR1 Transcription Factor in Zea mays

The BR-responsive genes are then regulated by BRASSINAZOLERESISTANT (BZR) Transcription Factors (TFs). As BRs possess numerous stress-resistant functions, BZR TFs also show activities of stress-resistance along with other developmental functions. Up to 88% similarity of protein sequences has been observed between BZR1 and BZR2 genes. Many positive roles of BZR TFs have been revealed by many studies in positively regulating the BR signal transduction in rice and maize family, but there is a very limited research is available on the BZR gene family of Zea mays. The aim of this study is to perform a wide-genome analysis of BZR1 transcription factor in Zea mays so that regulatory role of BZR TFs in BR-induced signaling pathway can be revealed. Gene structure analysis revealed the information about exons and introns. Phylogenetic analysis was done to identify the maximum likelihood among different families of BZR genes. Restriction analysis provided the information about the presence of restriction sites in Zea mays genome.
