In a previous note I asked, "Mottling expression is curious, and so is blotching — what is responsible?" This note does not answer the question but gives more information.Typical mottling of r/r/R kernels shows colored aleurone cells in irregular, scattered distributions that are inconsistent with the morphogenesis of the aleurone layer. Tantalizing cluesappear with highly paramutant Rl-iv or Rl-v (four or five times paramutagenized), in which pigmented cells are greatly reduced in frequency. The distributions suggest some systematic process is at play. Photographs at high magnification have been added to the database (Figs. 1A-G).

机译：在上一个笔记中，我问道：“对表情进行好奇是好奇的，对污点也是如此-是什么原因？”本注释并未回答问题，但提供了更多信息。r / r / R粒的典型斑点显示，彩色糊粉细胞呈不规则，分散的分布，与糊粉层的形态发生不一致。诱人的线索出现在高度变异的Rl-iv或Rl-v中（发生变异的四到五次），其中色素细胞的频率大大降低。分布表明一些系统过程正在发挥作用。高倍率照片已添加到数据库中（图1A-G）。
