Description | Brassica oleracea displays enormous phenotypic variation, including leafy vegetables (cabbage, kale, Brussels sprouts), tuber crops (kohlrabi) and inflorescences (cauliflower, broccoli). Brassica genomes all have undergone a whole genome triplication (WGT) which facilitated this phenotype diversification. We study the so called domestication events.
In two PhD projects, the molecular pathways involved in leafy head development of cabbages are studied. This will result in the identification of genes that either define whether the plant makes a leafy head or not (domestication genes) and genes that influence head size and shape. We will test the function of these gene by either expressing them in non-heading B. oleracea morphotypes, or by knocking them out in cabbage lines. For this we need to set up an efficient transformation system. The student will screen protocols, and perform transformation experiments with constructs containing both selection and reporter genes. When successfull, the student will also be involved in the generation of constructs to OE or Knock Out (CrisprCAs) candidate genes. |
