Baf1 Encodes an AT-Hook Transcriptional Regulator.

(A) Schematic representation of the map-based cloning of the Baf1 locus. Boxed are the syntenic regions analyzed for candidate genes in both sorghum and rice.

(B) Amino acid sequence of the BAF1 protein. In green is the amino acid sequence of the AT-hook DNA binding motif, whereas in blue is the PPC domain (DUF296).

(C) Schematic representation of the Baf1 gene and of the lesions identified in the baf1-ref and baf1-IL mutants. The white triangle represents a deletion.

(D) and (E) Transient expression of the BAF1-YFP fusion protein (D) and YFP (E) in tobacco leaves.
