Dark transformations of phytochrome in cotyledons of Pharbitis nil
スポンサーリンク
概要
- 論文の詳細を見る
Pharbitis seedlings grown in total darkness or continuous far-red irradiation were exposed to 30 min of red irradiation followed by a dark period, and in vivo phytochrome in their cotyledons was photometrically assayed at various times. Loss of photo-reversibility of P_<fr> after the exposure to red light occurred without dark reversion to P_r in cotyledons of both seedlings. P_<fr> decay in the former cotyledons was mostly prevented in the first 30 min under red light illumination, while that in the latter occurred without such a lag phase. P_<fr> was no longer photometrically detectable by the eighth hr after irradiation at both 18℃ and 25℃. No evidence has yet been obtained to show a correlation between photometrically detectable phytochrome in vivo and the red far-red reversible responses of flowering.
