Figure 1: Fruit exocarp colour phenotypes.
From: The oil palm VIRESCENS gene controls fruit colour and encodes a R2R3-MYB

(a) Individual oil palm fruits from a nigrescens (Nig) fruit bunch. Unripe fruits are deep-violet to black at the apex (visible in the bunch) and undergo minimal colour change upon ripening. (b) Individual oil palm fruits from a virescens (Vir) fruit bunch. Unripe fruits are green at the apex and change to reddish orange upon ripening. (c) ripe nigrescens and virescens fruit bunches.
