Rice MYB protein OSMYB5 specifically binds to the AACA motif conserved among promoters of genes for storage protein glutelin.
Binding analyses revealed that the AAC--A sequence in glutelin gene promoters is the target site of OSMYB5 protein and that both the distal and proximal AACA motifs are recognized by this protein. These results suggest that the OSMYB5 protein functions as a trans-acting factor for glutelin gene expression.
