Abstract:

The transcription factors in MYB family are widely involved in a variety of plant biological processes,among which R2R3-MYB is the most abundant type and has the most extensive functions. Previous studies have shown that some R2R3-MYB transcription factors can regulate the development of glandular secretory trichomes and the biosynthesis of artemisinin in Artemisia annua,however,the relevant studies are still little. Based on the genome data of A. annua,132 sequences of R2R3-MYB transcription factors were identified by local BLAST and HMMsearch,and their conserved domains were analyzed. Meanwhile,a phylogenetic tree of R2R3-MYB transcription factors between A. annua and Arabidopsis thaliana was constructed,and the functions of R2R3-MYB transcription factors were predicted with BLAST2GO. In addition,the expression patterns of R2R3-MYB genes in different tissues were analyzed based on transcriptome databases. Synthesizing the above bioinformatics analysis data,the genes of R2R3-MYB transcription factor that may participate in artemisinin biosynthesis are obtained,which provides the evidences for screening the genes of R2R3-MYB transcription factors involved in key biological processes.
