Genomic Synteny in Legumes; Application to Crop Breeding

点击翻译按钮获取中文摘要

Synteny is defined as the degree of colinearity between the order of orthologous genes in chromosomes of related species. New data suggests that legumes share widespread synteny. Extensive genomic resources are being accumulated for the model legume, Medicago truncatula including the full genome sequence. We propose to use these resources to uncover patterns of synteny between M. truncatula and the cultivated legumes chickpeas, lupins, faba-beans, lentils and lucerne. In addition to revealing patterns of chromosomal evolution in this large plant family, we will generate genetic maps and molecular markers for use in practical plant breeding of these important crops.
