Genome-wide identification and expression analysis of the bHLH transcription factor family and its response to abiotic stress in sorghum [Sorghum bicolor (L.) Moench].

ABSTRACT:

Background

Basic helix-loop-helix (bHLH) is a superfamily of transcription factors that is widely found in plants and animals, and is the second largest transcription factor family in eukaryotes after MYB. They have been shown to be important regulatory components in tissue development and many different biological processes. However, no systemic analysis of the bHLH transcription factor family has yet been reported in Sorghum bicolor.

Results

We conducted the first genome-wide analysis of the bHLH transcription factor family of Sorghum bicolor and identified 174 SbbHLH genes. Phylogenetic analysis of SbbHLH proteins and 158 Arabidopsis thaliana bHLH proteins was performed to determine their homology. In addition, conserved motifs, gene structure, chromosomal spread, and gen
