摘要：MYB proteins are one of the most abundant transcription factor families in the plant kingdom. Evidence has increasingly revealed that MYB-related proteins function in diverse plant biological processes. However, little is known about the genome-wide characterization and functions of MYB-related proteins in Populus, an important model and commercial tree species. In this study, 152 PtrMYBRs were identified and unevenly located on 19 Populus chromosomes. A phylogenetic analysis divided them into six major subgroups, supported by conserved gene organization, consensus motifs, and protein domain architecture. Promoter assessment and gene ontology classification results indicated that the MYB-related family is likely involved in plant development and responses to various environmental stressors. The Populus MYB-related family members showed various expression patterns in different tissues and stress conditions, implying their crucial roles in the development and stress responses in Populus. Co-expression analyses revealed that Populus MYB-related genes might participate in the regulation of antioxidant defense system and various signaling pathways in response to stress. The three-dimensional struc-tures of different subgroup of Populus MYB-related proteins further provided functional information at the proteomic level. These findings provide valuable information for a prospective functional dissection of MYB-related proteins and genetic improvement of Populus.
