Associations between MADS box transcription factors from ginger and turmeric, sorghum rhizome-enriched ESTs, and rice rhizomatous QTLs on rice chromosomes 2, 3, 6, 7, and 10. Orange boxes represent rhizome QTLs, while triangles indicate the spatial locations of MADS box genes on the rice chromosomes. Rice MADS box genes are illustrated using white triangles; black triangles are ginger/turmeric Blastx hits (e-values < e^-20). * denotes the best Blastx hits for the ginger and turmeric contig/rice gene comparison. † denotes a MADS box gene shown by microarray analysis to be preferentially expressed in the rhizome when compared to leaf or root tissues (Figure 3D & E).
