MYB transcription factors in Peucedanum Praeruptorum Dunn: the diverse roles of the R2R3-MYB subfamily in mediating coumarin biosynthesis.

ABSTRACT:

Background

The MYB superfamily (v-myb avian myeloblastosis viral oncogene homolog) plays a role in plant growth and development, environmental stress defense, and synthesis of secondary metabolites. Little is known about the regulatory function of MYB genes in Peucedanum praeruptorum Dunn, although many MYB family members, especially R2R3-MYB genes, have been extensively studied in model plants.

Results

A total of 157 R2R3-MYB transcription factors from P. praeruptorum were identified using bioinformatics analysis. Comprehensive analyses including chromosome location, microsynteny, gene structure, conserved motif, phylogenetic tree, and conserved domain were further performed. The length of the 157 transcription factors ranged from 120 to 1,688 amino acids (molecular weight
