Abstract

A variety of vesicular inclusions have been observed in guard-cell walls. They have been seen in a number of species and are mostly membrane-bound. They appear confined to the upper and ventral walls of the guard cell. A number of possible origins and functions are discussed. They may be involved in wall deposition or cuticle formation possibly in a role similar to ectodesmata. They also may serve to increase the wall-plasmalemma interface to enhance the movement of ions during the stomatal mechanism.

摘要

在保卫细胞壁中观察到了多种囊泡内含物。它们在许多物种中都有发现,并且大多有膜包裹。它们似乎局限于保卫细胞的上壁和腹侧壁。文中讨论了一些可能的起源和功能。它们可能参与壁的沉积或角质层的形成,其作用可能类似于外连丝。它们也可能有助于增加壁-质膜界面,以在气孔机制中增强离子的移动。
