(a) Schematic representation of the full-length RMYB gene layout after RACE analysis. Solid black lines indicate coding region (690 bp), orange color dotted lines indicate 5′ UTR region, and blue dotted lines indicate 3′ UTR region while the sequence of AAAAAA indicates the poly-A tail region of the translated product of the gene. (b) The green box represents the two active SANT/MYB domains in the cDNA sequence as predicted by the Pfam protein family database. (c) The complete schematic presentation of the translated product of RMYB gene. The gray colored amino acids represent the R2R3 MYB DNA-binding domains.
