Fig. 4: Genome-wide association for storage root flesh color in sweet potato.

From: Genome-wide analysis of expression quantitative trait loci (eQTLs) reveals the regulatory architecture of gene expression variation in the storage roots of sweet potato

Fig. 4

a Manhattan plot for storage root flesh color. The red horizontal dashed line represents the genome-wide significance threshold (−log10(P) = 6.68, α = 0.05). The red triangle corresponds to the proposed functional site (presence/absence variation of IbMYB1-2). b IbMYB1-2 was significantly (P < 2.2 × 10−16) differentially expressed between purple and nonpurple sweet potato accessions. c Manhattan plot from the eQTL mapping of IbMYB1-2. The red horizontal dashed line represents the genome-wide suggestive threshold (−log10(P) = 5.39, α = 1). d Summary of the distribution of the IbMYB1-2 mutation in sweet potato germplasm
