Phytochrome of oat (Avena sativa L., cv. Garry) coleoptile cells in the red-light-absorbing form, Pr, is diffusely distributed while after conversion to the far-red-light-absorbing form, Pfr, it is observed only in very small areas within the cell. Comparison of phytochrome photoversibility measurements to the distribution of the pigment within the cell indicates that the spectral assay is not influenced by the observed compartmentalization of the chromoprotein. However, the observed compartmentalization of phytochrome is correlated with a loss in spectrophotometrically detectable Pr.
燕麦（Avena sativa L.，cv. Garry）中胚细胞的光敏色素在红光吸收形式 Pr 中呈弥散分布，而在远红光吸收形式 Pfr 中仅在细胞内的非常小区域观察到。将光敏色素光可逆性测量值与细胞内色素分布进行比较表明，光谱测定不受观察到的色素蛋白隔室化的影响。然而，观察到的光敏色素的隔室化与分光光度法可检测到的 Pr 的损失相关。
