吸收红光/远红光的光感受器光敏色素调节生长和发育，因此在优化无柄植物对不断变化的环境的适应中发挥重要作用。我们对光敏色素如何吸收红色/远红光子引发/修改各种生理反应的理解一直在稳步提高。在过去5年中进行的研究特别富有成效，并导致了有关这些光感受器的作用模式的重大概念变化。光敏色素B是光生植物中最主要的光敏色素受体。我们讨论了它的光依赖性失活（称为黑暗/热逆转），翻译后修饰，包括泛素化，磷酸化和sumoylation，以及异源二聚体与其他光敏色素物种修改红光控制的生理反应。最后，我们讨论了光敏色素B的光生物学特性如何使这种感光器也作为一个热敏元件。
The red/far-red light absorbing photoreceptors phytochromes regulate development and growth and thus play an essential role in optimizing adaptation of the sessile plants to the ever-changing environment. Our understanding of how absorption of a red/far-red photon by phytochromes initiates/modifies diverse physiological responses has been steadily improving. Research performed in the last 5 years has been especially productive and led to significant conceptual changes about the mode of action of these photoreceptors. In this review, we focus on the phytochrome B photoreceptor, the major phytochrome species active in light-grown plants. We discuss how its light-independent inactivation (termed dark/thermal reversion), post-translational modification, including ubiquitination, phosphorylation and sumoylation, as well as heterodimerization with other phytochrome species modify red light-controlled physiological responses. Finally, we discuss how photobiological properties of phytochrome B enable this photoreceptor to function also as a thermosensor.
