Cloning and expression analysis of RtMYB1 gene from Reaumuria trigyna

The MYB transcription factor family plays an important regulatory role in imparting resistance to abiotic stress in plants. Based on transcriptome sequencing data, an MYB transcription factor was cloned from a rare secretohalophyte, Reaumuria trigyna, and named RtMYB1. The RtMYB1 gene has an ORF of 780 bp, encoding 236 amino acid residues. Expression of the RtMYB1 gene can be induced by stress factors, including salt, cold, high temperature, ultraviolet radiation(UV), and drought (PEG), indicating that the gene may be involved in regulating the response of R. trigyna to abiotic stress. This study lays the foundations to explore and better understand the resistance mechanisms against abiotic stress in R. trigyna.
