摘要/Abstract

摘要：

近年来围绕大气CO2浓度升高下植物光合适应现象的研究不断深入,植物光合作用对CO2浓度升高适应的可能原因主要表现在以下几个方面：CO2浓度升高下所增强的光合作用导致碳水化合物的过量积累以及光合电子传递链中质体醌与过氧化氢（H2O2）的氧化还原信号对光合作用发生反馈抑制;核酮糖1,5-二磷酸羧化/加氧酶（Rubisco）的含量及其活性的下降;气孔状态的变化.此外,植物体内C/N平衡、生长调节物质和己糖激酶对光合基因表达水平的调控等多个方面也会对光合适应产生影响.

关键词: 大气CO2浓度光合适应反馈抑制核酮糖1,5-二磷酸羧化/加氧酶气孔

Abstract:

With the rapid increasing in atmospheric CO2 concentration, people have a deep study in photosynthetic response to high CO2 concentrations, the reasons in photosynthetic acclimation to high CO2 concentrations might include that： the feedback bohydrate and redox signals arising from the plastoq peroxide changes restrain to photosynthesis caused by deposit of car- uinone pool and from the accumulation of hydrogen ; decrease of rubisco content and activity was induced by levels of rubisco subunit mRNA; in stomata states. In addition, the levels of photosynthesis gene expression induced by C/N balance, plant growth regulators and hexoses might also result in photosynthetic acclimation.

Key words: atmospheric CO2 , photosynthetic acclimation , feedback restrain , rubisco , stomata
