Transcriptome Wide Characterization of Water Deficit Responsive Grape MTERF Transcription

Abstract

Plant mitochondrial transcription termination factor (mTERF) is a large and important family with valuable roles in organizing of organelle gene expression under the various stresses. In this study, genome wide analysis of mTERF regulatory genes was achieved and twenty-five potential mTERF genes response water deficit in grape (Vitis vinifera L.) were determined. Most of them were targeted to organelles genome especially mitochondria. It was found that Grape mTERFs were clustered into six main groups based on phylogenetic analysis. As a result of comprehensive expression analysis of these genes, using RNA-seq data in this study revealed that these genes have various expression profiles. With this study, various important roles of mTERF genes of grape under the water deficit stress were reported at first in grape. All results were found will be useful for elucidating the roles of mTERF genes in the growth, development and stress response of grape and fundamental for functional genomic studies.
