eQTL mapping of candidate genes for flower colour as a model for genetical genomics in azalea Research Institute for Agriculture, Fisheries and Food
Flower colour in azalea is inherited as a semi-qualitative trait and is mainly determined by differences in anthocyanins and flavonols. A two-gene model is used to explain the phenotypic variation between white, brick red and carmine red colour: W in case the flower petals contain anthocyanins and Q if flavonols are present as co-pigments. However, the regulatory network behind this pathway is still unclear. To identify key driver genes of the ...
