Abstract
The DNA-binding with one zinc finger (Dof) family of plant-specific transcription factors has a variety of important functions in gene transcriptional regulation, development, and stress responses. However, the structure and expression patterns of Dof family have not been identified in Cleistogenes songorica, which is an important xerophytic and perennial gramineous grass in desert grassland. In this study, 50 Dof genes were identified in C. songorica and could be classified into four groups. According to genome-wide analysis, 46 of 50 Dof genes were located on 20 chromosomes, and the gene structure and conserved protein motif of these proteins were analyzed. In addition, phylogenetic analysis of Dof genes in C. songorica, Arabidopsis thaliana, Oryza sativa, and Brachypodium distachyon estimated the evolutionary relationships, and these genes were grouped into seven clusters. Moreover, the expression profiles of these Dof genes in C. songorica were analyzed in response to high/low temperature, salinity, and ABA treatments. These results will provide valuable information for future studies on gene classification, cloning, and functional characterization of this family in C. songorica.
Highlights
Transcription factors (TFs) are a group of proteins with important roles in controlling cell activities, such as physiological balance, biochemical reactions, and responses to the environment [1,2,3]
The DNA-binding with one finger (Dof ) TFs is a representative of the plant-specific transcription factor gene family, which is closely related to physiological and biochemical reactions during plant growth and development [7,8]
A total of 50 Dof genes were identified in the C. songorica genome database [41]
Summary
Transcription factors (TFs) are a group of proteins with important roles in controlling cell activities, such as physiological balance, biochemical reactions, and responses to the environment [1,2,3]. They determine the transcription rate of genes by binding the cisregulatory elements of promoters [4], and regulate interactions of proteins in a complex network [5,6]. The DNA-binding with one finger (Dof ) TFs is a representative of the plant-specific transcription factor gene family, which is closely related to physiological and biochemical reactions during plant growth and development [7,8]. It has been reported that the Dof transcription factors have diverse functions that are unique to plant growth and development in many species, such as carbon metabolism in maize [24]
