Field-grown plants experience fluctuating light intensity for periods extending from seconds to hours because of cloud movements and self-shading. When full light intensity returns after shading, the net CO2 assimilation rate in leaves does not reach its maximum value immediately, but rises gradually over several minutes to approach a new steady state. This phenomenon has been termed photosynthetic induction, which substantially affects the efficiency of carbon fixation, and thus crop production. The significant natural variation of the speed of induction response exists among not only interspecies but also intraspecies. Recent advances in molecular analysis and high-throughput measurement techniques have revealed the genetic and eco-physiological basis of observed genetic variations in photosynthetic induction response. Here, we review the current understanding of the physiological and genetic mechanisms behind photosynthetic induction, and discusses routes to further advances.

光合诱导对波动光环境的自然遗传变异。

田间生长的植物由于云运动和自遮蔽，经历了几秒钟到几小时不等的光强波动。遮光后，当全光强度恢复时，叶片中的净CO2同化率不会立即达到其最大值，而是会在几分钟内逐渐升高以达到新的稳态。这种现象被称为光合作用诱导，它实质上影响碳固定的效率，进而影响农作物的生产。诱导反应速度的显着自然变化不仅存在于种间，也存在于种内。分子分析和高通量测量技术的最新进展揭示了在光合作用诱导反应中观察到的遗传变异的遗传和生态生理基础。这里，
