Recent results indicate that (1) Oryzeae is monophyletic and falls into two main clades corresponding to the traditionally recognized subtribes;(2) Close affinities of the monoecious genera are not supported, suggesting the multiple origins of unisexual florets;(3) Previous recognition of three monotypic genera (Hydrochloa, Porteresia and Prosphytochloa) is not justified;(4) Based on dating using molecular clock approach, it is estimated that Oryza and Leersia branched off from the remaining genera of Oryzeae -20 million years ago, and separated from each other -14 MYA.
目前已有的研究结果表明:稻族是单系类群,可分为两个主要分支,相当于传统的两个亚族(Zizaniinae和Oryzinae),但稻族单性花小穗是多次起源的,不宜作为划分亚族的依据;一些单型属(Hydrochloa、Porteresia和Prosphytochloa)的建立得不到分子证据的支持;根据分子钟原理估计稻族两个主要分支的分歧时间在大约2000万年前,而稻属和近缘属假稻属Leersia的分歧时间为1400万年:稻属内主要类群的分歧时间在900万年前左右。
