The MYB proteins comprise one of the largest families of transcription factors (TFs) in plants. Although several  MYB  genes have been characterized to play roles in secondary metabolism, the MYB family has not yet been identified in apple. In this study, 229 apple  MYB  genes were identified through a genome-wide analysis and divided into 45 subgroups. A computational analysis was conducted using the apple genomic database to yield a complete overview of the MYB family, including the intron-exon organizations, the sequence features of the MYB DNA-binding domains, the carboxy-terminal motifs, and the chromosomal locations. Subsequently, the expression of 18  MYB  genes, including 12 were chosen from stress-related subgroups, while another 6 ones from other subgroups, in response to various abiotic stresses was examined. It was found that several of these  MYB  genes, particularly  MdoMYB121 , were induced by multiple stresses. The  MdoMYB121  was then further functionally characterized. Its predicted protein was found to be localized in the nucleus. A transgenic analysis indicated that the overexpression of the  MdoMYB121  gene remarkably enhanced the tolerance to high salinity, drought, and cold stresses in transgenic tomato and apple plants. Our results indicate that the  MYB  genes are highly conserved in plant species and that  MdoMYB121  can be used as a target gene in genetic engineering approaches to improve the tolerance of plants to multiple abiotic stresses.
