在谷类种子中，母体组织和胚乳之间没有共质体连接。小麦颖果的珠心突起及其对侧胚乳上皮细胞分化为转运细胞，以利于溶质的转运。对小麦胚乳传递细胞（ETC）和珠心突起传递细胞（NPTC）进行了对比观察和研究。实验结果表明，ETC和NPTC之间既有相似之处，也有不同之处。ETC和NPTC几乎同步发展。ETC和NPTC的壁内突首先在离胚乳腔最近的第一层中形成，然后在离胚乳腔较远的内层中形成。成熟的ETC主要为三层结构，成熟的NPTC主要为四层结构。ETC壁内突为凸缘型，NPTC壁内突为网状型。NPTC不是营养物质的贮藏细胞，但ETC第一层具有糊粉细胞特征，第二层和第三层积累淀粉粒和蛋白体。
In cereal seed, there are no symplastic connections between the maternal tissues and the endosperm. In order to facilitate solute transport, both the nucellar projection and its opposite endosperm epithelial cells in wheat caryopsis differentiate into transfer cells. In this paper, we did contrast observation and investigation of wheat endosperm transfer cells (ETC) and nucellar projection transfer cells (NPTC). The experimental results showed that there were some similarities and differences between ETC and NPTC. ETC and NPTC almost developed synchronously. Wall ingrowths of ETC and NPTC formed firstly in the first layer nearest to the endosperm cavity, and formed later in the inner layer further from the endosperm cavity. The mature ETC were mainly three layers and the mature NPTC were mainly four layers. Wall ingrowths of ETC were flange type and wall ingrowths of NPTC were reticulate type. NPTC were not nutrient-storing cells, but the first layer of ETC had aleurone cell features, and the second layer and third layer of ETC accumulated starch granules and protein bodies.
