The Co-expression Analysis of MYB Transcription Factors from Arabidopsis and Rice

다국어 초록 (Multilingual Abstract)

MYB proteins are a superfamily of transcription factors (TF) that play regulatory roles in developmental processes and resistance mechanism in plants. We identified 130 and 109 genes in the MYB superfamily from an analysis of the complete Arabidopsis and rice genome sequence. Although microarray based transcriptome analysis approach allows the investigation of the biological networks of MYB TF in DNA level, the underling mechanisms related to their functional role is not fully understood. In this work, we performed meta-analysis of public microarray data that analyzed with Arabidopsis and rice using co-expression analysis. A phylogenetic comparison of the members of this superfamily were performed with Sorghum bicolour to suggested that MYB super family underwent a rapid expansion their evolutionary times. We identified conserved expression pairs which play important role in transcription. Our comprehensive analysis of this huge transcription factor of Arabidopsis and rice may shed further light on the possible biological roles of the MYB TF in various plants.
