In the Zea mays L. mutant M11 grown in the dark at 15 degrees , the ultrastructure of the etioplast is abnormal. The pigment content of the etioplasts is reduced but the in vivo absorption characteristics suggest that the normal protochlorophyll (ide)-holochrome is present. The lowered synthetic ability of the etioplasts is not primarily due to a reduced complement of plastid ribosomes. The plastids of mutant M11 grown in the light at 15 degrees contain little pigment, are markedly deficient in ribosomes and their ultrastructure is abnormal. In mutant M11 grown at 15 degrees , an extreme sensitivity of the plastid membranes to light was observed.
在15摄氏度黑暗条件下生长的玉米（Zea mays L.）突变体M11中，黄化质体的超微结构异常。黄化质体的色素含量降低，但体内吸收特性表明存在正常的原叶绿素（ide）-全色素。黄化质体合成能力降低并非主要由于质体核糖体数量减少。在15摄氏度光照条件下生长的突变体M11的质体几乎不含色素，核糖体明显缺乏，其超微结构异常。在15摄氏度条件下生长的突变体M11中，观察到质体膜对光极度敏感。
