太陽光中包含了紅光與遠紅光,在白天,陽光包含的紅光比遠紅光更多。 這代表著將會有更多的 Pr 轉化為 Pfr,反之亦然。 但是,到了晚上,Pfr 的光敏色素會變回 Pr。 這也就是說,白天 Pfr 的濃度會升高。 夜間,Pr 的濃度便會升高。 這是Pr 和 Pfr 光敏色素上升和下降的交互作用。 當夏季有著較長的日照時間,...
PHYTOCHROME is a plant photomorphogenetic pigment existing in two forms, Pr and Pfr, interconvertible by light, which have absorption peaks in the red and far-red regions of the spectrum respectively1,2. Intermediates between Pr and Pfr have been studied by several techniques ...

To solve the question regarding the light wavelengths absorbed by phytochrome R (P_r) and phytochrome FR (P_fr), we can follow these steps: 1. Identify the Types of Phytochrome: - Phytochrome exists in two interconvertible forms: Pr (phytochrome red) and Pfr (phytochrome far-red). 2. ...
By absorbing light, phytochromes reversibly convert between the inactive Pr and the active Pfr state, which have absorption peaks in red (R, 660 nm) and far-red light (FR, 720 nm), respectively. The R and FR light content in the environment therefore determines the relative level of ...
It is essential for light reception and photoconversion between reversible conformations that absorb maximally in the red (650–670 nm) or far-red (705–740 nm) regions of the spectrum, referred to as Pr and Pfr, respectively. The C-terminal module consists of a PAS–PAS repeat followed by...
PHYB is a red/far-red photoreceptor involved in the regulation of de-etiolation. It exists in two inter-convertiBle forms: Pr and Pfr (active) . It is involved in the light-promotion of seed germination and in the shade avoidance response.应用...
