特定种子蛋白的积累是分类学上有价值的特征，并且可以用于另外表征植物分类群。迄今为止，主要在禾本科中分析作物蛋白。在这项调查中，从147个物种的种子蛋白筛选，重点是豆类蛋白和醇溶蛋白。从蛋白质谱的评价得到的组对应于众所周知的亚家族和族。Panicoideae与Pooideae明显分离。在早熟禾亚科内，雀麦族和小麦族之间存在着明显的相似性。黑麦草属、羊茅属和狐茅属，通常包括在羊茅族中，揭示了与雀麦族/小麦族的蛋白质谱相似的蛋白质谱。豆科蛋白质在除雀麦族/小麦族以外的竹亚科和早熟禾亚科中大量积累，然而，只有燕麦亚族中包括的物种产生“可溶性"（球蛋白型）豆科蛋白质，如已知的燕麦。
The accumulation of specific seed proteins is a taxonomically valuable feature and can be used to additionally characterize plant taxa. To date, mainly crop proteins have been analysed in the Poaceae. In this investigation seed proteins from 147 species were screened with emphasis on legumin-like proteins and prolamins. The groups resulting from evaluation of the protein profiles correspond with well-known subfamilies and tribes. Panicoideae are clearly separated from Pooideae. Within Pooideae, the Bromeae plus Triticeae tribes revealed obvious similarities. Lolium, Festuca and Vulpia, generally included in the tribe Festuceae, revealed a protein profile similar to the profile of the Bromeae/Triticeae. Legumin-like proteins are accumulated abundantly in Bambusoideae and Pooideae except Bromeae/Triticeae, however, only the species included in the Aveninae subtribe produce ''soluble'' (globulin-type) legumins as already known from Avena sativa.
