Abstract: R2R3-MYB transcription factors of Arabidopsis play important roles in regulatory networks controlling development, metabolism and responses to biotic and abiotic stresses. R2R3-MYB transcription factors can be divided into 25 subfamilies based on the conserved amino acid sequences. In these subfamilies, the 22nd subfamily that responses to biotic and abiotic stresses includ AtMYB44, AtMYB77, AtMYB73 and AtMYB70. In this review, we summarize these 4 genes of the 22nd subfamily from three aspects, including the similarity of gene function, consistency of gene expression and conservation of the genetic structure. Then we discuss the redundancy and diversity about gene structure and function of these 4 genes.

Key words: R2R3-MYB transcription factors, 22 subfamily, structure and function
