Figure 4.

Several known causal loci show statistically significant associations with plant height when sequential genome-wide association studies are conducted using data anchored to the date of panicle emergence. A summary of where statistically significant trait-associated SNPs were identified in separate genome-wide association studies conducted using height data for each day between −14 to +10 DAPE. Each vertical column summarizes the results from one of the 25 independently conducted genome-wide association studies. Each sorghum chromosome is divided into 16 bins containing equal numbers of SNP markers. Each cell in each vertical column is color coded based on the single most significant P-value observed for any marker within that bin on that day. Light pink cells indicate bins that contain no markers that exceed the multiple testing-corrected threshold for statistical significance. The locations of the two cloned dwarf genes and the one cloned maturity gene which were successfully identified in analysis of data from at least one time point are indicated with horizontal dashed lines.
