| description | <i>MYB</i> transcription factors are one of the largest transcription factor families in plants, and they regulate numerous biological processes. Red algae are an important taxonomic group and have important roles in economics and research. However, no comprehensive analysis of the <i>MYB</i> gene family in any red algae, including <i>Pyropia yezoensis</i>, has been conducted. To identify the <i>MYB</i> gene members of <i>Py. yezoensis</i>, and to investigate their family structural features and expression profile characteristics, a study was conducted. In this study, 3 <i>R2R3</i>-<i>MYB</i>s and 13 <i>MYB</i>-related members were identified in <i>Py. yezoensis</i>. Phylogenetic analysis indicated that most red algae <i>MYB</i> genes could be clustered with green plants or Glaucophyta <i>MYB</i> genes, inferring their ancient origins. Synteny analysis indicated that 13 and 5 <i>PyMYB</i> genes were orthologous to <i>Pyropia haitanensis</i> and <i>Porphyra umbilicalis</i>, respectively. Most Bangiaceae <i>MYB</i> genes contain several Gly-rich motifs, which may be the result of an adaptation to carbon limitations and maintenance of important regulatory functions. An expression profile analysis showed that <i>PyMYB</i> genes exhibited diverse expression profiles. However, the expression patterns of different members appeared to be diverse, and <i>PyMYB5</i> was upregulated in response to dehydration, low temperature, and <i>Pythium porphyrae infection</i>. This is the first comprehensive study of the <i>MYB</i> gene family in <i>Py. Yezoensis</i> and it provides vital insights into the functional divergence of <i>MYB</i> genes. |
