通过对俄罗斯产棘豆属植物叶绿体DNA的trnH-psbA、trnL-trnF和trnS-trnG基因间隔区的核苷酸序列分析，阐明了棘豆亚属和层棘豆亚属部分种和组以及整个棘豆属的系统发育关系。只有Mesogaea组对应于Phacoxytropis亚属，而同一亚属的Janthina组与Oxytropis亚属的组一起。棘豆属亚属的狭叶棘豆组和直叶棘豆组不仅彼此关系密切，而且与中生棘豆组一起被归为层棘豆亚属。看来似乎应该把红蕊花组和直蕊花组归入Phacoxytropis亚属，而Janthina组归入Oxytropis亚属。在分子水平上与O. coerulea和O. mandshurica从节Janthina的，这表明相当大的分歧，其叶绿体基因组和物种的独立性的类群。O. czukotica属于Arctobia组也得到了确认。
The nucleotide sequence analysis of trnH-psbA, trnL-trnF, and trnS-trnG intergenic spacer regions of chloroplast DNA performed in the representatives of the genus Oxytropis from Asian Russia provided clarification of the phylogenetic relationships of some species and sections in the subgenera Oxytropis and Phacoxytropis and in the genus Oxytropis as a whole. Only the section Mesogaea corresponds to the subgenus Phacoxytropis, while the section Janthina of the same subgenus groups together with the sections of the subgenus Oxytropis. The sections Chrysantha and Ortholoma of the subgenus Oxytropis are not only closely related to each other, but together with the section Mesogaea, they are grouped into the subgenus Phacoxytropis. It seems likely that the sections Chrysantha and Ortholoma should be assigned to the subgenus Phacoxytropis, and the section Janthina should be assigned to the subgenus Oxytropis. The molecular differences were identified between O. coerulea and O. mandshurica from the section Janthina that were indicative of considerable divergence of their chloroplast genomes and the species independence of the taxa. The species independence of O. czukotica belonging to the section Arctobia was also confirmed.
