Berries, such as strawberry, raspberry and black currant, are well appreciated for their delicate flavor and nutraceutical properties, with consumer demand increasing over the last years. However, climate change and market globalization have made necessary to improve the production while maintaining fruit quality traits.
Among the EU GoodBerry project’s objetive are develop state-of-the-art analytical platforms, covering from transcriptomic to metabolites and volatile compounds analysis, to find new factors controlling plant adaptation, fruit production and quality and use the data to face climate changes. Here we present the metabolomic analysis of strawberry, raspberry and black currant fruits from the 2017 harvest.
Different berry cultivars, adapted to diverse environments, were grown in 2017 and 2018 in different latitudes (Germany, France, Norway, Italy and Poland) combination of spectrometry techniques was used to semi-quantify fruit primary metabolome and volatilome.
Around 50 key primary metabolites, including sugars and acids, which are fundamental factors influencing fruit taste and 75 volatiles, responsible of the aroma, were identified across the different genotypes and climates. Multivariate statistical approaches allow us to point out the genetic and environmental factors underlying complex metabolic traits involved in fruit quality.
