Circadian rhythms in plants are relatively robust, as they are maintained both in constant light of high fluence rates and in darkness. Plant circadian clocks exhibit the expected modes of photoentrainment, including period modulation by ambient light and phase resetting by brief light pulses. Several of the phytochrome and cryptochrome photoreceptors responsible have been studied in detail. This review concentrates on the resulting patterns of entrainment and on the multiple proposed mechanisms of light input to the circadian oscillator components.
植物中的昼夜节律相对稳定，因为它们在高通量的持续光照和黑暗环境中都能维持。植物生物钟表现出预期的光诱导模式，包括环境光对周期的调节以及短暂光脉冲对相位的重置。已经对几种负责的光敏色素和隐花色素光感受器进行了详细研究。本综述重点关注由此产生的诱导模式以及向生物钟振荡器组件输入光的多种 proposed 机制。 （注：“proposed”此处疑有误，暂保留英文未翻译准确）
