通过对染色体工程法培育出的小麦新品种M8003及其亲本种子的麦谷蛋白进行SDS—PAGE分析,结果表明:M8003麦谷蛋白的绝大部分亚基组成与其回交亲本“中国春”相似,而其第6,7,8三个亚基条带与非回交亲本奥地利黑麦的第5,6,7三个亚基条带带型相同,说明M8003麦谷蛋白的6,7,8三种亚基是来自奥地利黑麦染色体基因编码的,进一步证明了M8003属于小麦—黑麦异易位系的细胞学鉴定结果。 SDS-PAGE analysis of wheat glutenin, a new wheat cultivar M8003 and its parental seed, developed by chromosome engineering showed that most of the subunit composition of M8003 glutenin was similar to that of its backcrossing parent “Chinese Spring” The 6th, 7th and 8th subunit bands are the same as the 5th, 6th and 7th subunit bands of the non-backcross parent Austrian rye, indicating that 6, 7, 8 three subtypes of M8003 glutenin The base was derived from the gene encoding the rye chromosome in Austria, further confirming the cytological identification of M8003 belonging to the wheat-rye heterotranslocation.
