The Casparian strip is commonly observed in the endodermis of roots of vascular plants and, in some cases, also in the stems. Pea stems develop the Casparian strip, and its development has been reported to be regulated by blue light. In addition, for the purpose of photobiological studies, pea stems provide a unique experimental system for other physiological studies of the development of the Casparian strip. In this article, I have briefly summarized (1) the effects of environmental factors on the development of the Casparian strip, (2) the advantage of using pea stems for physiological studies of the development of the Casparian strip, and (3) cellular events indicated to be involved in the development of the Casparian strip, focusing on the studies using pea stems as well as other recent studies.
凯氏带普遍存在于维管植物根的内皮层中，在某些情况下也存在于茎中。豌豆茎会形成凯氏带，其发育受蓝光调控。此外，为了进行光生物学研究，豌豆茎为凯氏带发育的其他生理研究提供了一个独特的实验系统。在本文中，我简要总结了（1）环境因素对凯氏带发育的影响，（2）使用豌豆茎进行凯氏带发育的生理研究的优势，以及（3）与凯氏带发育相关的细胞事件，重点介绍了使用豌豆茎的研究以及其他最近的研究。
