We have studied the effects of six high-lysine barley mutations (Risø mutants 1508 and 56, Notch 1 and 2, lys 95 and 449) on the protein fractions of the grain. All mutants had a decreased relative and total amount of the lysine-poor hordein fraction, but only in Risø 1508 and 56 was the polypeptide composition of this fraction greatly affected. In all the mutants there were increases in the lysine-rich glutelin proteins and in nonprotein N while in Risø 1508 and the Notch mutants the total amount of salt-soluble proteins was also increased and their relative polypeptide composition substantially altered.
我们研究了六种高赖氨酸大麦突变体（里瑟突变体1508和56、缺口1和2、lys 95和449）对谷物蛋白质组分的影响。所有突变体中，赖氨酸含量低的醇溶蛋白组分的相对含量和总量均有所降低，但只有里瑟1508和56中该组分的多肽组成受到极大影响。在所有突变体中，富含赖氨酸的谷蛋白和非蛋白氮含量均增加，而在里瑟1508和缺口突变体中，盐溶性蛋白质总量也增加，其相对多肽组成发生了显著变化。
