“…The effects of unique and CAbS factors (namely, drought, salinity, cold, high temperature, submergence, and UV and metal stresses) are the major bottleneck for plant growth, development, and productivity (Grennan, 2006;Mittler, 2006;Mittler and Blumwald, 2010;Breviario and Genga, 2013;Muthuramalingam et al, 2017;Pandey et al, 2017;Muthuramalingam et al, 2018a;Wani W. et al, 2018). The MYB TFs have been involved in various developmental processes, meristem formation, AbS, and physiological responses such as plant development, environmental stimuli, cell fate and identity, cell differentiation, proliferation, anatomical structure development, phenylpropanoid biosynthesis, determination of cell shape, floral and seed development, cell cycle control, and plant defenses (Noda et al, 1994;Abe et al, 2003;Araki et al, 2004;Hichri et al, 2011;Katiyar et al, 2012;Ambawat et al, 2013;Yang et al, 2014;Smita et al, 2015;Deeba et al, 2017).…”

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, Oryza sativa (OsMYB). This study retrieved 114 OsMYB TFs that were computationally analyzed for their expression profiling, gene organization, cis-acting elements, and physicochemical properties. Based on the microarray datasets, six OsMYB genes which were sorted out and identified by a differential expression pattern were noted in various tissues. Systematic expression profiling of OsMYB 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 OsMYB genes in related C4 grass plants conferred the gene synteny. Protein–protein interactions of these genes revealed the molecular crosstalk of OsMYB TFs. Transcriptional analysis (qPCR) of six OsMYB players in response to drought and salinity stress suggested the involvement in individual and combined AbS responses. To decipher how these OsMYB play functional roles in AbS dynamics, further research is a prerequisite.
