采用透射电镜对69种石竹属植物的筛元质体进行了研究。它们都含有以蛋白丝外环为特征的特异性亚型- p - 3质体。存在或不存在额外的中心蛋白晶体，它们的形状是多角形或球形，以及筛元质体的平均大小是一些家族特征的有用特征。Barbeuia含有筛元质体，这证实了它在植物科中的地位。Lyallia与Hectorella的不同之处在于其筛元质体中含有小的淀粉粒，否则它们的球状晶体会否定与石竹科的更紧密联系。微茶在其p3fs型质体中缺乏中心蛋白晶体，在藜科中处于最佳位置。石竹属（Sarcobatus）是藜科（Chenopodiaceae）中一个迄今为止没有争议的成员，它含有form-P3cf质体，也就是说，包括一个在该科其他地方没有发现的中心晶体。Telephium和Corrigiola在Molluginaceae和石竹科之间来回移动，具有具有多边形晶体的form-P3cf(s)质体，这有利于它们在石竹科中的位置。
The sieve-element plastids of 69 species of the Caryophyllales were investigate by transmission electron microscopy. All contained the specific subtype-P 3 plastids characterized by a peripheral ring of protein filaments. The presence or absence of an additional central protein crystal and their shape being either polygonal or globular as well as the average sizes of the sieve-element plastids are useful features in the characterization of some families. - Barbeuia contains sieve-element plastids that confirm its placement within the Phytolaccaceae. Lyallia differs from Hectorella by including small starch grains in their sieve-element plastids, which otherwise by their globular crystals negate a closer connection to the Caryophyllaceae. The lack of a central protein crystal in its form-P3fs plastids places Microtea best within the Chenopodiaceae. Sarcobatus, a so far uncontested member of the Chenopodiaceae, contains form-P3cf plastids, i.e., including a central crystal not found elsewhere in this family. Telephium and Corrigiola, shifted back and forth between Molluginaceae and Caryophyllaceae, have form-P3cf(s) plastids with a polygonal crystal which favor their placement within the Caryophyllaceae.
