Abstract

The aim of this project is to investigate methods of influencing recombination. In the case of Lolium chromosome 3, chiasmata tend to be located at the distal ends of the chromosome where traditionally genes have been described as being located. Recent work indicates a more even distribution of genes including the central regions of the chromosome where recombination frequencies are much lower. This raises interest in inducing recombination in these regions in order to break them up for the assortment of alleles into new and novel arrangements for use in plant breeding, gene cloning etc.

The method currently being investigated is through the influence of B chromosomes, which are known to be linked to changes in recombination frequency and distribution. Plants with varying numbers of Bs are hybridised and analysed with SSR markers to determine the frequency and distribution of recombination events. Comparisons between plants of different B chromosome complements can then be directly compared.
