A global taxonomic resource for the nightshade family

July 30th, 2021 - Remco Stam

We are starting the Second Season of SolSeminarsOnline! Our first one will be presented by Remco Stam on Differences in biotic stress responses in diverse populations of Solanum chilense

Abstract. Wild tomato species form an intriguing group of wild plant species. Each have their own specific habitats and corresponding ecological niches, though some overlap in their ranges does exist. In a patchwork of studies several dozens of different pathogen resistance properties have been identified in for a number of pathogens in several of the species. However, systematic analyses of such resistances and the underlying genetic variation within wild tomato species are sparse. We are especially interested in understanding such variation and evolution of pathogen resistance properties in a true demographic/ecological context. Our work predominantly focuses on the wild tomato species Solanum chilense. The species grows on the southern edges of the species range for wild tomato and its very specific demography, resulting from two different expansions into extreme environments make it the ideal species to study phenotypic and genetic diversity of biotic defences. In this talk, I will highlight several aspects of recent research projects. These range from genomics analyses that indicate clear resistance gene family evolution to phenotypic and biochemical studies that show tremendous variations in defence hormone responses between and within wild tomato populations.
