Genome-wide identification of BcMYB in Bupleurum Chinense DC. and its regulatory roles in saikosaponins synthesis under temperature stress.

ABSTRACT:

Background

MYB transcription factors play critical roles in secondary metabolite biosynthesis in medicinal plants and are crucial for abiotic stress responses. However, no studies have identified BcMYB genes in Bupleurum chinense DC. or analyzed their expression profiling under temperature stress. The role of BcMYB in ​B. chinense's response to temperature stress and its regulation of saikosaponins synthesis remains unclear.

Results

This study performed a genome-wide identification of the BcMYB gene family in B. chinense using its genomic data, and analyzed the changes in saikosaponins content, physiological indicators, and BcMYB expression patterns under temperature stress, along with their correlations with saikosaponin biosynthesis. A total of 85 BcMYBs genes were identif
