Figure 3. Association mapping results in CAM155 and graph of pairwise LD between significantly associated polymorphic sites of Zmfatb.

(A) Sites that were significantly associated with variation in the palmitic acid composition in Hainan, 2007. (B) The structure and functional domain of Zmfatb. Filled black boxes represent exons, open boxes indicate the UTR and the gray dashed boxes mark the region sequenced in this study. And the grey ellipse represents the acyl-ACP thioesterase domain encoded by the third, fourth, fifth and sixth exons. (C) A representation of the pair-wise r² among the significantly associated sites, where darker shading of each box corresponds to a higher r². The red stars and black dashed lines represent the most significant polymorphic loci.
