Genomic (SG)-PCR and RT-PCR of Adh1 and Adh2. Bands of the molecular marker from the bottom up denote size standards of 0.1 kb, 0.2 kb, 0.5 kb, 0.75 kb, 1 kb and 2 kb. Row a is SG-PCR of Adh1 and Adh2 in 'Cuiguan'(C1, C2), 'Korlaxiangli' (K1, K2), 'Nanguoli' (N1, N2) and 'Flemish Beauty'(F1, F2); Rows b, c and d are RT-PCR of Adh1, Adh2 and control Actin gene in investigated tissues and cultivars. Cs, Cl and Cf denote seed, leaf and fruit of 'Cuiguan', respectively; Kf, Nf, Ff and Mf-fruit denote fruit of 'Korlaxiangli', 'Nanguoli', 'Flemish beauty' and 'Fuji', respectively.
