description As an important nongrain crop, the growth and yield of potato (<i>Solanum tuberosum</i> L.) is often affected by an unfavorable external environment in the process of cultivation. The MYB family is one of the largest and most important gene families, participating in the regulation of plant growth and development and response to abiotic stresses. Several <i>MYB</i> genes in potato that regulate anthocyanin synthesis and participate in abiotic stress responses have been identified. To identify all <i>Solanum tuberosum</i> L. <i>MYB</i> (<i>StMYB</i>) genes involved in hormone or stress responses to potentially regulate potato growth and development, we identified the MYB gene family at the genome-wide level. In this work, 158 <i>StMYB</i> genes were found in the potato genome. According to the amino acid sequence of the MYB domain and gene structure, the <i>StMYB</i> genes were divided into R2R3-MYB and R1R2R3-MYB families, and the R2R3-MYB family was divided into 20 subgroups (SGs). The expression of 21 <i>StMYB</i> genes from different SGs in roots, stems, leaves, flowers, shoots, stolons, young tubers, and mature tubers was determined by quantitative real-time polymerase chain reaction (qRT-PCR). The expression patterns of <i>StMYB</i> genes in potatoes treated with abscisic acid (ABA), indole-3-acetic acid (IAA), gibberellin acid 3 (GA3), NaCl, mannitol, and heat were also measured. We have identified several potential candidate genes that regulate the synthesis of potato flavonoids or participate in hormone or stress responses. This work provides a comprehensive understanding of the MYB family in potato and will lay a foundation for the future investigation of the potential functions of <i>StMYB</i> genes in the growth and development of potato.
