Figure 2: Genetic architecture variation in selective sweeps (SSW).

From: Genome-wide study of an elite rice pedigree reveals a complex history of genetic architecture for breeding improvement

Figure 2

(a,b) Screening of SSWs on chromosome 1 (a) and chromosome 6 (b); the y-axis on the left represents the negative logarithm of the Pi or Theta value; the y-axis on the right represents Tajima’s D. Both Sd1 (a) and Wx (a) were screened out with low Tajima’s D. Pi (blue), Theta (red), and Tajima’s D (green) were calculated in 100-kb windows across one chromosome. (c) Full scope of SSW genotype and four variation clusters; each row stands for one SSW block, and each column stands for one cultivar. Cluster 1: selection before 2000; cluster 2: selection before 2007; cluster 3: selection after 2008; cluster 4: selection from 1950 to 2014. Three colors are used to indicate genotypes identical to that of Huanghuazhan (red), different from that of Huanghuazhan (green), or lacking data (gray). (d) Major character of reported genes located in SSWs from four different clusters.
