Amino acid composition of prolamins and the whole seed in representatives of 52 cereal genera and 22 tribes, as well as amino acid composition of seed protein fractions in representatives of 9 cereal genera are presented. In terms of proposed directed evolution of the seed proteins and adaptive role of prolamins in evolution and distribution of cereals, generalized data on their content in seed protein complex, electrophoretic, immunochemical, and amino acid composition of the seeds, we develop the notion of prolamins biochemical specialization and their polyphyletic origin during evolution of cereal seed protein complex. Seven adaptive types of prolamins are recognized: Sasa, Molinia, Chloris, Zingeria, Poa, Triticum, and Panicum types. Adaptive types of prolamins were formed in response to an ecological request of the environment where taxon ancestors existed and a taxon appeared and in relation to phylogenetic history of a taxon and its assignment to particular tribe and subfamily.
本文展示了52个谷物属和22个族代表的醇溶蛋白及整个种子的氨基酸组成，以及9个谷物属代表的种子蛋白组分的氨基酸组成。根据提出的种子蛋白定向进化以及醇溶蛋白在谷物进化和分布中的适应性作用，我们基于种子蛋白复合体中醇溶蛋白的含量、种子的电泳、免疫化学和氨基酸组成的综合数据，提出了醇溶蛋白生化特化及其在谷物种子蛋白复合体进化过程中的多系起源的概念。识别出七种醇溶蛋白的适应类型：笹竹型、黑麦草型、虎尾草型、三蕊草型、早熟禾型、小麦型和黍型。醇溶蛋白的适应类型是为响应分类单元祖先存在和分类单元出现的环境的生态需求，以及与分类单元的系统发育历史及其归属于特定族和亚科的关系而形成的。
