The analysis of the evolutionary origins and consequences of polyploidy in Trifolium spp.
Polyploidy plays a key role in generating new phenotypes by increasing allelic diversity and fixing heterozygosity and has therefore a potential as a tool for crop improvement. We are interested in understanding the impact of this process on the evolution and domestication of white clover. We are using a combination of molecular phylogenetic and cytogenetic approaches to elucidate the relationship between white clover (Trifolium repens) and its close wild diploid relatives. We are also carrying out inter-specific crosses to be used in assessing the effect of hybridisation and genome duplication on key genes and to develop populations for dissecting the genetic architecture of key traits in white clover.
