Inheritance Beyond Plain Heritability: Variance-Controlling Genes in Arabidopsis thaliana
Figure 4
Detection of a variance-controlling locus (Variance in Serration - VS) affecting Leaf serration at 16°C.
a: Manhattan plot for genetic association with Leaf serration at 16°C in the plant. The yellow dots in the front are the genomic controlled p-values from the Wilcoxon (difference in mean) test. The other colored dots are the genomic controlled p-values from the Brown-Forsythe (difference in variance) test, where the colors are used to separate the 5 chromosomes. The horizontal dashed line corresponds to a nominal 5% significance threshold with Bonferroni correction. b: Two overlapping histograms showing the phenotypic distributions per genotype of the VS locus. c: The distribution of LD across the VS locus. d: Association signals around the VS locus where the annotated genes are illustrated by shades in red (gene-name available) or gray (gene-name unavailable).
