暴露后，一半的低光适应菜豆（菜豆）叶片强光，叶绿素（Chl）荧光参数，如PSII的操作效率，PSII最大效率在光下，和光化学猝灭，在同一叶片的另一半下降，而抗氰呼吸途径的能力显着增加。当一半的弱光适应叶暴露于弱光，1 mM水杨基异羟肟酸（SHAM，抗氰呼吸途径的抑制剂）预处理的另一半没有表现出显着的变化，叶绿素荧光值相比，没有SHAM预处理。然而，暴露后的一半低光适应叶强光，1 mM SHAM预处理的另一半显示较低的叶绿素荧光值比没有SHAM预处理。我们的研究结果表明，部分曝光的低光适应叶片强光可以施加系统压力的PSII光化学。增强的抗氰呼吸途径的能力可能参与维持光合性能在叶片组织经历强光诱导的系统性胁迫。
After exposing one half of a low light-adapted kidney bean (Phaseolus vulgaris) leaf to high light, parameters of chlorophyll (Chl)afluorescence, such as PSII operating efficiency, PSII maximum efficiency under light, and photochemical quenching, decreased in the opposite half of the same leaf, whereas the capacity of the cyanide-resistant respiratory pathway significantly increased. When one half of the low light-adapted leaf was exposed to low light, the opposite half pretreated with 1 mM salicylhydroxamic acid (SHAM, an inhibitor of the cyanide-resistant respiratory pathway) did not exhibit significant changes in the Chl fluorescence values compared with the without SHAM pretreatment. However, after exposing one half of the low light-adapted leaf to high light, the opposite half pretreated with 1 mM SHAM showed lower Chl fluorescence values than that without SHAM pretreatment. Our results indicate that partial exposure of the low light-adapted leaf to high light can impose a systemic stress on the PSII photochemistry. The enhanced capacity of the cyanide-resistant respiratory pathway may be involved in the maintenance of the photosynthetic performance in the leaf tissues experiencing high light-induced systemic stress.
