FAR1/FHY3 Transcription Factors Positively Regulate the Salt and Temperature Stress Responses in .

FAR-RED ELONGATED HYPOCOTYLS3 (FHY3) and its homolog FAR-RED IMPAIRED RESPONSE1 (FAR1), which play pivotal roles in plant growth and development, are essential for the photo-induced phyA nuclear accumulation and subsequent photoreaction. The FAR1/FHY3 family has been systematically characterized in some plants, but not in . In this study, genome-wide identification of genes in was performed using bioinformatic methods. The gene structures, chromosomal locations, the encoded protein characteristics, 3D models, phylogenetic relationships, and promoter -elements were analyzed with this gene family. A total of 33 genes were identified in , which were divided into three groups based on their phylogenetic relationships. A total of 21 pairs of duplicated repeats were identified by homology analysis. Gene expression analysis showed that most genes were differentially expressed in a spatial-specific manner. Gene expression analysis also showed that genes responded to salt and temperature stresses. These results and observation will enhance our understanding of the evolution and function of the genes in and facilitate further studies on the molecular mechanism of the gene family in growth and development regulations, especially in response to salt and temperature.
