Seeing the Forest through the (Phylogenetic) Trees: Functional Characterisation of Grapevine Terpene Synthase (VviTPS) Paralogues and Orthologues.

ABSTRACT: Gene families involved in specialised metabolism play a key role in a myriad of ecophysiological and biochemical functions. The Vitis vinifera sesquiterpene synthases represent the largest subfamily of grapevine terpene synthase (VviTPS) genes and are important volatile metabolites for wine flavour and aroma, as well as ecophysiological interactions. The functional characterisation of VviTPS genes is complicated by a reliance on a single reference genome that greatly underrepresents this large gene family, exacerbated by extensive duplications and paralogy. The recent release of multiple phased diploid grapevine genomes, as well as extensive whole-genome resequencing efforts, provide a wealth of new sequence information that can be utilised to overcome the limitations
