Genetic analysis of a white-to-red berry skin color reversion and its transcriptomic and metabolic consequences in grapevine (Vitis vinifera cv. 'Moscatel Galego').

ABSTRACT:

Background

Somatic mutations occurring within meristems of vegetative propagation material have had a major role in increasing the genetic diversity of the domesticated grapevine (Vitis vinifera subsp. vinifera). The most well studied somatic variation in this species is the one affecting fruit pigmentation, leading to a plethora of different berry skin colors. Color depletion and reversion are often observed in the field. In this study we analyzed the origin of a novel white-to-red skin color reversion and studied its possible metabolic and transcriptomic consequences on cv. 'Muscat à Petits Grains Blancs' (synonym cv. 'Moscatel Galego Branco'), a member of the large family of Muscats.

Results

The mild red-skinned variant (cv. 'Muscat à Petits Grains Rouge', synonym cv. 'Mo
