qPCR – Relative expression of F3GT1 , MYB10 and MYB110a in petals. Gene expression analysis of MYB10 (primer set Ke922), MYB110a (primer set Ke923) and F3GT1 (Flavonoid 3-O-galactosyltransferase) in petals of white and red flowers of an interspecific Actinidia hybrid (A. chinensis var. chinensis x A. eriantha) x A. chinensis var. chinensis at two stages of flower development: calyx split and open flower. Error bars are SE for four technical replicates of each genotype.
