根据叶绿体DNA rps 16内含子序列的变异，推测了大豆亚族13个属、Polhill将其归入大豆亚族的近缘种Diocleinae亚族的2个属以及作为外群的刺桐亚族的2个属之间的系统发育关系。两两序列的差异值在同一性范围内。micans和T. flexilis和T.在所有材料中，野葛根和假单胞菌之间的唇型比例为7.89%。用简约法和邻接法估计的系统发育关系表明：（1）大豆亚科是单系的，（2）Teramnus属与Glycine属亲缘关系较近，Amphalipaea属与Teramnus和Glycine属的分支有姐妹关系;（3）扩大后的大豆亚科（Glycininae）包括二属（Diocleinae），分为三个分支，暂定名为I（包括其余的检查分类群），II（野葛根（Pueraria wallichii）），和（Mastersia），但他们的关系是模棱两可的;（4）葛藤属（Pueraria）与大豆属（Glycine）是近缘属，但不是单系的，至少应分为4个属（雷基曾提出这一假说）。
Phylogenetic relationships among 13 genera of the subtribe Glycininae, two genera of the allied subtribe Diocleinae that were included within Glycininae by Polhill, and two genera of the subtribe Erythrininae as outgroups were inferred from chloroplast DNA rps16 intron sequence variation. Pairwise sequence divergence values ranged from identity between Teramnus mollis and T. micans and between T. flexilis and T. labialis to 7.89% between Pueraria wallichii and Pseudeminia comosa across all accessions. Phylogenies estimated using parsimony and neighbor-joining methods revealed that (1) Glycininae is monophyletic if Pachyrhizus and Calopogonium (both Diocleinae) are included within Glycininae; (2) the genus Teramnus is closely related to Glycine, and Amphicarpaea showed a sister relationship to the clade comprising Teramnus and Glycine; (3) the expanded Glycininae including two genera of Diocleinae is divided into three branches, temporarily named I (comprising the rest of the examined taxa), II (Pueraria wallichii), and III (Mastersia), but their relationships are equivocal; and (4) the genus Pueraria, regarded as a closely related genus to Glycine, is not monophyletic and should be divided into at least four genera (a hypothesis supported previously by Lackey).
