  • Titre: Variability in flavour composition in tomato and genetics for improvement
  • Summary : Tomato has been used for many years as a model for fruit ripening and more recently for the identification of the molecular genetic basis of what makes tomato a healthy and palatable fruit. Organoleptic and nutritional quality in this climacteric fruit is regulated at different levels and metabolites associated with organoleptic and nutritional composition are part of the ripening process and increasingly the target/focus of geneticists and breeders. The nutritional value of tomato fruit is not based on calories but on the healthy compounds they provide to our diet. Many of the plant/tomato nutritional and healthy compounds are often precursors of compounds that contribute to flavour what supports the contention that good flavour and healthy compounds are part of the mechanism plants use to reward frugivors for dispersing the seed contained in their fruits. Breeding or Biotech approaches aimed to higher nutritional content should go with good flavour to really have an impact on consumers,In my presentation I will illustrate examples were the use of genetic resources in combination with high throughput genotyping and phenotyping and biotech approaches is contributing to generate variation in tomato health and flavour composition and to identifying genomic regions, markers and genes associated /underlying the variation in compounds of organoleptic or nutritional value. I will also present how Plant Biotechnology and Synthetic Biology approaches are used in our lab to further expand the natural variation in fruit metabolites.
  • Biography: Antonio Granell is a Research Professor at CSIC. Durig his PhD he did pioneering work with pathogenesis related proteins and then moved as a post doc to work for more than three years on plant molecular genetics at the Plant Science Institute in Penn University (Cashmore’s lab). He then joined the Plant Group at the Instituto de Agroquímica in Valencia to work on plant senescence. Since 2006 his main interest has been fruit quality using tomato as model system but sometimes also in Citrus and Peach fruit. A huge effort has been put into developing technologies (omics technologies; specially metabolomics, and transcriptomics), participation in international consortia such as the Tomato Sequencing Consortium and in making the genomic information available to the plant research community (chillpeach and ESPSOL data bases and partipation in Solgenomics). Antonio is group leader of PGB, scientific coordinator of the metabolomics facility and he is in charge of the Molecular Breeding projects.
