Global Integrated Genomic and Transcriptomic Analyses of MYB Transcription Factor Superfamily in C3 Model Plant (L.) Unravel Potential Candidates Involved in Abiotic Stress Signaling.

Plant transcription factors (TFs) are significant players in transcriptional regulations, signal transduction, and constitute an integral part of signaling networks. MYB TFs are major TF superfamilies that play pivotal roles in regulation of transcriptional reprogramming, physiological processes, and abiotic stress (AbS) responses. To explore the understanding of MYB TFs, genome and transcriptome-wide identification was performed in the C3 model plant, (). This study retrieved 114 TFs that were computationally analyzed for their expression profiling, gene organization, -acting elements, and physicochemical properties. Based on the microarray datasets, six genes which were sorted out and identified by a differential expression pattern were noted in various tissues. Systematic expression profiling of TFs showed their meta-differential expression of different AbS treatments, spatio-temporal gene expression of various tissues and their growth in the field, and gene expression profiling in responses to phytohormones. In addition, the circular ideogram of genes in related C4 grass plants conferred the gene synteny. Protein-protein interactions of these genes revealed the molecular crosstalk of TFs. Transcriptional analysis (qPCR) of six players in response to drought and salinity stress suggested the involvement in individual and combined AbS responses. To decipher how these play functional roles in AbS dynamics, further research is a prerequisite.
