摘要: CO2是植物光合作用的重要原料,而气孔阻力与叶肉阻力是CO2扩散进入叶绿体的最大限制因素。植物的气孔导度和叶肉导度对非生物胁迫因子非常敏感,这些因子通过调控羧化位点CO2浓度来影响光合速率。气孔导度对环境的响应,叶肉导度的内部结构、生化因素限制早已有了相关综述,然而围绕环境因子对植物CO2扩散的系统调控还未进行归纳和探讨。因此,本文综述了气孔导度和叶肉导度对非生物胁迫因子(如光强、干旱、CO2浓度和温度)的快速响应和长期应答及其调控的生理机制,并对今后的研究趋势做了进一步展望。

Abstract:

Plant photosynthesis assimilates CO2 from the atmosphere, and CO2 diffusion efficiency is mainly constrained by stomatal and mesophyll resistance.  The stomatal and mesophyll conductance of plants are sensitive to abiotic stress factors, which affect the CO2 concentrations at carboxylation sites to control photosynthetic rates.  Early studies conducted relevant reviews on the responses of stomatal conductance to the environment and the limitations of mesophyll conductance by internal structure and biochemical factors.  However, reviews on the abiotic stress factors that systematically regulate plant CO2 diffusion are rare.  Therefore, in this review, the rapid and long-term responses of stomatal and mesophyll conductance to abiotic stress factors (such as light intensity, drought, CO2 concentration and temperature) and their physiological mechanisms are summarized.  Finally, future research trends are also investigated.
