    Chromophore rotation in 124-k Dalton Avena sativa phytochrome as measured by light changes in linear dichroism1985In: Photochemistry and Photobiology, ISSN 0031-8655, E-ISSN 1751-1097, Vol. 41, p. 221-223Article in journal (Refereed)
    Abstract [en]

    From light-induced changes in linear dichroism, the rotation of the long-wavelength-absorbing transition moment that occurs during phototransformation of 124-kilodalton (kD) A. sativa phytochrome was calculated Phytochrome was purified to homogeneity and immobilized onto Sepharose beads covalently coated with antibodies against A. sativa phytochrome. Changes in linear dichroism were induced by plane-polarized red or far-red light and measured by the absorbance differences at 660 and 730 nm using a dual-wavelength spectrophotometer equipped with polarizing filters in the measuring beams. From such measurements, a rotation angle of 31° (or 149°) was calculated during photoconversion of Pr to Pfr and 30° (or 150°) during photoconversion of Pfr to Pr. These values are similar to the value of 32° (or 148°) reported earlier for the rotation of the transition moment of "large" A. sativa phytochrome (~120 kD) isolated under conditions that did not preclude post-homogenization proteolysis of the 124 kD mol.

    Photosynthetic activity in marine and brackish water strains of Fucus vesiculosus and Fucus radicans (Phaeophyceae) at different light qualities2012In: Photochemistry and Photobiology, ISSN 0031-8655, E-ISSN 1751-1097, Vol. 88, no 6, p. 1455-1460Article in journal (Refereed)
    Abstract [en]

    This study investigates the effects of different light qualities on the photosynthetic capacity of the brown algae Fucus vesiculosus, from the Norwegian Sea, and Fucus radicans and F. vesiculosus, from the Bothnian Sea. The electron transport rates (ETR) obtained for F. vesiculosus from the Norwegian Sea showed significantly higher levels of light saturation compared with both species of algae from the Bothnian Sea. The maximum of ETR values for the Norwegian Sea strain showed no significant changes due to varying light quality compared with the initial values. For F. vesiculosus, from the Bothnian Sea, treatment with blue light showed an effect after 1 week of 30 and 90 μmol photons m -2 s -1 (P < 0.01), and for F. radicans from the Bothnian Sea, at the irradiance of 90 μmol photons m -2 s -1 and 1 week (P < 0.01). After 1 week in the Bothnian Sea species and after 2 weeks in F. vesiculosus from the Norwegian Sea, the photosynthetic efficiency (α) was significantly higher regardless of light quality and irradiance compared with the initial values. Variation in light quality and irradiance had minor effects on the F v:F m values of the three algal strains studied. © 2012 Wiley Periodicals, Inc.
