Research goals
Our research group is interested in understanding the genetic and molecular mechanisms responsible for reproductive development in grapevine. Our research activity is particularly focused on those traits which impact production and quality of grape and wine. To accomplish this goal we use a strategy based on the search, characterization and use of existent grapevine natural genetic variation for relevant reproductive traits. We also use genetic and genomic tools to understand the genetic and molecular basis of the observed phenotypic variation.
Following these approaches our research activity is focused in two main research lines:
1. Prospection, conservation and phenotypic and genetic characterization of grapevine genetic resources. In the short run the goal is to collect new genetic resources for the genetic analyses of variation in relevant agronomic traits. This includes search and characterization of wild plants, ancient varieties, somatic variants as well as the generation of genetic tools such as germplasm core collections and segregating progenies derived from out crossed and selfed plants. The use of these resources requires both phenotyping relevant traits related with reproductive development as well as genotyping based on SSR, SNP or NGS derived techniques.
2. Understanding the molecular basis of the variation in reproductive traits. Among them we consider those that impact on grape production and quality such as fertility, precocity, flowering and fruit set, cluster architecture and compactness, berry color, berry size and shape and seedlessness. This goal is focused on the identification of genes and gene variants responsible for trait natural variation using a combination of genetic (QTL analyses and genetic association analyses) and molecular and genomic tools such as genome and transcriptome sequence.
The generated knowledge and tools have direct application on the genetic identification of cultivars and somatic variants or in the identification of grapevine responses to different environmental factors and cultural practices. Moreover, they can be used in the design and development of clone improvement and cultivar breeding programs or to characterize the effect of different agricultural practices and improve their effect always with the goal of providing strategies to respond to the challenges of current and future viticulture.
