In this study, 181 <i>AcMYB</i> TFs were identified from the kiwifruit genome, unevenly distributed on 29 chromosomes. The high proportion (97.53%) of segmental duplication events (Ka/Ks values less than 1) indicated that <i>AcMYB</i> TFs underwent strong purification selection during evolution. According to the conservative structure, 91 <i>AcR2R3-MYB</i> TFs could be divided into 34 subgroups.
