小麦颖果发育过程中面筋蛋白的合成是高度协调的，开花后11天开始检测到各组的mRNA，14天左右开始检测到蛋白质。相反，BiP、PDI和PPI的转录水平在发育的早期阶段最高。参与分泌途径的两种小GTP结合蛋白（Rab1和Rab5）的转录水平在发育早期也是最高的，这与ER内大部分谷蛋白的保留形成蛋白体是一致的。
The synthesis of gluten proteins in the developing caryopsis of wheat is highly coordinated, with mRNAs for the various groups being detected from 11 days after anthesis, and the proteins from about 14 days. In contrast, the levels of transcripts for BiP, PDI and PPI are highest at earlier stages of development. The levels of transcripts for two small GTP binding proteins involved in the secretory pathway (Rab1 and Rab5) are also highest early in development, which is consistent with the retention of most of the gluten proteins within the ER to form protein bodies.
