Light is a pivotal environmental element capable of influencing multiple physiological processes across the entire plant life cycle. Over the course of their evolution, plants have developed several families of photoreceptors such as phytochromes, phototropins, UV resistance locus 8, and cryptochromes, in order to sense light stimuli and respond to their changes. Numerous genetic studies have demonstrated that functional alterations to these photoreceptors cause a change in important agronomical traits. In particular, cryptochromes, which absorb UVA/blue light, can influence seed germination, flowering induction, plant architecture, fruit metabolic content and resistance to biotic and abiotic stresses. In the years to come, the rising temperatures and alterations to precipitation patterns generated by climate change will present a dramatic challenge for our agricultural system, with its few varieties characterized by a narrow genetic pool derived from artificial selection. Here, we review the main roles of cryptochromes in determining important agronomic traits in crops, we discuss the opportunities of using these photoreceptors as genetic targets for tuning plant physiological responses to environmental change, and the molecular strategies used so far to manipulate this family of photoreceptors.

田间隐花色素：蓝光如何影响作物生长

光是一种关键的环境元素，能够影响整个植物生命周期的多个生理过程。在它们的进化过程中，植物已经发展出几个光感受器家族，例如光敏色素、光敏素、抗紫外线位点 8 和隐花色素，以便感知光刺激并对它们的变化做出反应。许多遗传研究表明，这些光感受器的功能改变会导致重要农艺性状的变化。特别是，吸收 UVA/蓝光的隐花色素可以影响种子发芽、开花诱导、植物结构、果实代谢含量以及对生物和非生物胁迫的抗性。在未来的岁月里，气候变化导致气温升高和降水模式改变，将对我们的农业系统构成巨大挑战，因为我们的农业系统很少，其特点是人工选择的遗传库狭窄。在这里，我们回顾了隐花色素在确定作物重要农艺性状方面的主要作用，我们讨论了使用这些光感受器作为调节植物对环境变化生理反应的遗传目标的机会，以及迄今为止用于操纵该光感受器家族的分子策略. 本文受版权保护。版权所有。我们回顾了隐花色素在确定作物重要农艺性状方面的主要作用，我们讨论了使用这些光感受器作为调节植物对环境变化生理反应的遗传目标的机会，以及迄今为止用于操纵该光感受器家族的分子策略。本文受版权保护。版权所有。我们回顾了隐花色素在确定作物重要农艺性状方面的主要作用，我们讨论了使用这些光感受器作为调节植物对环境变化生理反应的遗传目标的机会，以及迄今为止用于操纵该光感受器家族的分子策略。本文受版权保护。版权所有。
