The project concentrates on phylogeography, phylogeny and systematics of taxa of the onion genus Allium (family Alliaceae) with disjunctive distributions in the northern hemisphere. A detailed molecular phylogeny of subgenera Amerallium (with main focus on Eurasian species) and Anguinum, including date of distribution, ecology, chromosome number and morphology of the species of these subgenera will be used to reconstruct of the phylogeography and for understanding of the origin and development of Eurasian and North American disjunctive distributions in the genus Allium. On the basis of multiple gene analyses of nuclear- (ITS and ETS) and cpDNA (trnL-trnF, matK, rbcL-atpB) loci for taxa of the genus Allium (subgenera Anguinum and Amerallium), with Old World and New World disjunction, we will examine phylogenetic relationships and patterns of differentiation of the disjunctive taxa.

该项目集中于北方半球洋葱属间断分布植物的地理学、系统发生学和分类学研究。通过对亚属Amerallium（主要集中在欧亚种）和Anguinum的分子系统学研究，包括亚属的分布年代、生态学、染色体数目和形态学等方面的详细资料，将有助于重建亚属的地理分布，并有助于了解欧亚和北美分离分布的葱属起源和发展。基于多基因分析的核（ITS和ETS）和叶绿体DNA（trnL-trnF，matK，rbcL-atpB）位点的葱属（亚属Anguinum和Amerallium）的分类群，旧世界和新世界的分离，我们将研究系统发育关系和模式的分离分类群的分化。
