AB  - Myeloblastosis (MYB)-related transcription factors comprise a large subfamily of 
      the MYB family. They play significant roles in plant development and in stress 
      responses. However, MYB-related proteins have not been comprehensively 
      investigated in rapeseed (Brassica napus L.). In the present study, a genome-wide 
      analysis of MYB-related transcription factors was performed in rapeseed. We 
      identified 251 Brassica napus MYB (BnMYB)-related members, which were divided 
      phylogenetically into five clades. Evolutionary analysis suggested that whole 
      genome duplication and segmental duplication events have played a significant 
      role in the expansion of BnMYB-related gene family. Selective pressure of 
      BnMYB-related genes was estimated using the Ka/Ks ratio, which indicated that 
      BnMYB-related genes underwent strong purifying selection during evolution. In 
      silico analysis showed that various development-associated, 
      phytohormone-responsive, and stress-related cis-acting regulatory elements were 
      enriched in the promoter regions of BnMYB-related genes. Furthermore, MYB-related 
      genes with tissue or organ-specific, stress-responsive expression patterns were 
      identified in B. napus based on temporospatial and abiotic stress expression 
      profiles. Among the stress-responsive MYB-related genes, BnMRD107 was strongly 
      induced by drought stress, and was therefore selected for functional study. 
      Rapeseed seedlings overexpressing BnMRD107 showed improved resistance to osmotic 
      stress. Our findings not only lay a foundation for further functional 
      characterization of BnMYB-related genes, but also provide valuable clues to 
      determine candidate genes for future genetic improvement of B. napus.
