Genomic Synteny in Legumes; Application to Crop Breeding

同线性是指近缘物种染色体上直向同源基因顺序之间的共线性程度。 新的数据表明，豆科植物具有广泛的共线性。 正在为模式豆科植物蒺藜苜蓿积累广泛的基因组资源，包括全基因组序列。 我们建议使用这些资源来揭示M之间的共线性模式。蒺藜和栽培豆类鹰嘴豆、羽扇豆、蚕豆、小扁豆和卢塞恩。 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.
