Fig. 4.

Carotenoid biosynthetic gene expression in peel (a) and pulp (b) of ‘Navelate’ (grey bars) and ‘Pinalate’ mutant (black bars) fruits at green (G), breaker (B) and full ripe (R) stage, and (c) in young leaves of ‘Navelate’ and ‘Pinalate’ . Asterisks indicate significant differences between ‘Navelate’ and ‘Pinalate’ samples (p ≤ 0.01). Expression of ZDS3 and βLCY2 was not detected in leaves. PSY, phytoene synthase; PDS, phytoene desaturase; ZDS1,2 and 3, ζ-carotene desaturase; βLCY1, lycopene β-cyclase 1; βLCY2, chromoplast-specific lycopene β-cyclase2; βCHX, non-heme β-carotene hydroxylase
