Abstract

In maize mitochondria the effect of the herbicide amiprophosmethyl was studied on massive and limited Ca2+-loading and on mitochondrial energy transduction. Under massive Ca2+-loading conditions amiprophosmethyl inhibited the Ca2+ transport system directly without a significant effect on the respiratory chain, the membrane potential or Ca2+ efflux. Under limited Ca2+-loading conditions an increased Ca2+ efflux was noted, which could be partially responsible for the inhibition of the net Ca2+ accumulation.

摘要

在玉米线粒体中,研究了除草剂氨丙膦酸甲酯对大量和有限钙离子负载以及线粒体能量转导的影响。在大量钙离子负载条件下,氨丙膦酸甲酯直接抑制钙离子转运系统,而对呼吸链、膜电位或钙离子外流没有显著影响。在有限钙离子负载条件下,观察到钙离子外流增加,这可能部分导致了净钙离子积累的抑制。
