Genomic Synteny in Legumes; Application to Crop Breeding

同源性被定义为近缘物种染色体上的同源基因序列之间的共线性程度。新的数据表明，豆类具有广泛的同步性。模式豆科牧草紫花苜蓿正在积累丰富的基因组资源，包括全基因组序列。我们打算利用这些资源来揭示豆科植物鹰嘴豆、羽扇豆角、蚕豆、小扁豆和紫花苜蓿之间的同步性模式。除了揭示这个大植物家族的染色体进化模式外，我们还将生成遗传图谱和分子标记，用于这些重要作物的实际植物育种。

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.
