Abstract

The envelope of the spinach chloroplast is a yellow membrane system with a unique carotenoid composition. Envelopes prepared from dark-treated leaves had a violaxanthin content up to 3.5 times the lutein plus zeaxanthin content, whereas in chloroplast envelopes from illuminated leaves this ratio was only 0.75. Light-catalyzed changes in violaxanthin content also occurred in the thylakoid fraction.The role of this reversible light-catalyzed de-epoxidation of violaxanthin in the function of the envelope of the chloroplast is discussed.

摘要

菠菜叶绿体被膜是一种具有独特类胡萝卜素组成的黄色膜系统。从暗处理叶片制备的被膜中,紫黄质含量高达叶黄素与玉米黄质含量之和的3.5倍,而在光照叶片的叶绿体被膜中,该比例仅为0.75。类囊体部分也发生了紫黄质含量的光催化变化。本文讨论了紫黄质这种可逆的光催化脱环氧化作用在叶绿体被膜功能中的作用。
