Low resistance junctions were demonstrated between cells in anthers from young buds of Lilium longiflorum Croft by standard electrophysiological techniques. Electrodes containing a dye were used to stain impaled cells for later histological identification. Electrical coupling is widespread; germinal cells are coupled to one another; coupling is also observed between somatic elements, and germinal and somatic cells are similarly interconnected. Cytoplasmic bridges are implicated in the first case; plasmodesmata are probably responsible for the interactions in the other two. Although the physiological role of the low resistance junctions shown here and present in embryonic animal tissues is unknown, the possible function of this form of intercellular communication in the development of the anther is discussed.
通过标准电生理技术,在麝香百合幼蕾花药的细胞间证实了低电阻连接。使用含有染料的电极对刺入的细胞进行染色,以便后续进行组织学鉴定。电耦合广泛存在;生殖细胞相互耦合;在体细胞成分之间也观察到耦合,并且生殖细胞和体细胞也以类似方式相互连接。第一种情况涉及细胞质桥;胞间连丝可能是另外两种相互作用的原因。尽管此处显示的以及存在于胚胎动物组织中的低电阻连接的生理作用尚不清楚,但本文讨论了这种细胞间通讯形式在花药发育中的可能功能。
