...Phytochrome is known to show a reversible change in upon irradiation with red or near-infrared light. In the dark, a conversion from Pfr to Pr (dark reversal) occurs, so it can be interpreted that when the dark period continues for a certain period of time, Pfr falls below the critical concentration, inducing flowering in short-day plants. However, since the rate of decrease in Pfr depends on temperature, whereas the critical dark period of photoperiodism is not affected by temperature, it is difficult to explain flowering solely by the decrease in Pfr . ... *Some of the terminology that refers to "dark inversion" is listed below.

…フィトクロムは赤色光あるいは近赤外光の照射によって,の可逆的変化を示すことがわかっているからである。暗所ではPfrからPrへの転換(暗反転)がおこるので,一定時間以上の暗期が継続した場合にPfrが限界濃度以下になって短日植物の花成を誘導すると解釈できる。しかし,Pfrの減少速度は温度に依存するのに対して光周性の限界暗期は温度に影響されないので,Pfrの減少のみで花成を説明することは困難である。… ※「暗反転」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
