Description Cultivated tomato (Solanum lycopersicum) is attacked by a wide range of insects. These cause severe damage, both directly through feeding and indirectly by the viruses they transmit. Resistance against insects is found in wild relatives of the cultivated tomato. Solanum galapagense shows resistance against sucking insects in which trichomes type IV play a crucial role. Resistance against the caterpillar Spodoptera exigua, which is also found in the species, seems to be independent of trichomes. QTLs for trichome based and caterpillar resistance have been identified and are currently being characterized. Students can participate in the characterization of the resistance mechanism, including trichome development, as well as identification of genes and metabolites involved.
Used skills Depending on the project, perform insect bioassays, molecular marker analysis, molecular biology. Analyse the data and write a thesis.
