Identification and analysis of 1R-MYB transcription factors regulating the phenylpropane biosynthesis pathway in Ranunculus japonicus Thunb.
The 1R-MYB family plays a crucial role in plant growth,development,stress resistance,and se-condary metabolite synthesis.A full-length transcriptome database for three different tissues of Ranunculus japonicus Thunb.was constructed using PacBio isoform sequencing and DNA nanoball sequencing.In this study,members of the 1R-MYB family were identified in the full-length transcriptome database of R.japonicus.Their motifs,family evolution,expression patterns,spatial structure,and functions were analyzed.In total,221 MYB-related genes were identified at the transcriptome level,with 18 1R-MYB transcription factors(TFs)found to be enriched in the phenylpropanoid biosynthesis pathway based on KEGG analysis,potentially regu-lating peroxidase activity.Overall,this study provides a foundation for further exploration of the regulatory functions of 1R-MYB TFs in secondary metabolite biosynthesis in R.japonicus.
