Genetic analysis of seed dormancy and seed composition in Arabidopsis thaliana using natural variation
2002
Bentsink, L.
The model plant Arabidopsis thaliana has a broad natural distribution throughout the Northern Hemisphere therefor many different accessions could be collected from natural populations and are available for experimental analysis. These accessions provide an alternative source of genetic variation that can be used to study the function of genes.The main aim of the work presented in this thesis is to increase the knowledge about the genetic control of seed dormancy. Therefore the natural variation present between two Arabidopsis accessions; Landsberg erecta and Cape Verde Islands has been analysed for this character. This analyses revealed several loci involved in seed dormancy, one of them has been further characterised and fine-mapped. In addition other seed traits that might be related to seed dormancy and germination have been analysed. These traits are seed oligosaccharide content, seed storability and seed phytate and phosphate content.
