Journal ArticleDOI
Nonphotochemical Transformations of Phytochrome in Vivo.
TL;DR: 2 nonphotochemical processes which appear to involve phytochrome as a reactant are reported which are accompanied by another dark reaction which results in a loss of reversible phy tochrome in dark-grown seedlings.
Journal ArticleDOI
Low temperature spectral properties of subchloroplast fractions purified from spinach.
Kimiyuki Satoh,Warren L. Butler +1 more
TL;DR: The different fractions of Spinach (Spinacia oleracea L.) chloroplasts separated into five fractions showed unique polypeptide patterns and unique sets of low temperature- absorbing forms of chlorophyll.
Journal ArticleDOI
Photoreceptor Pigment for Blue Light in Neurospora crassa
Victor Muñoz,Warren L. Butler +1 more
TL;DR: In this article, it was shown that the action spectrum for the photoreduction of a b-type cytochrome b is very similar to the absorption spectrum of flavin pigments.
Journal ArticleDOI
Inhibition of the Hill Reaction by Tris and Restoration by Electron Donation to Photosystem II
TL;DR: Experiments in which chloroplasts were washed with tris and tricine buffers at different pH's indicated that the non-protonated (uncharged) form of tris was inhibitory to the Hill reaction while the protonated form oftris and the zwitterionic forms oftricine were non-inhibitory.
Journal ArticleDOI
The spectrophotometry of dense light-scattering material
Warren L. Butler,Karl H. Norris +1 more
TL;DR: The photoreversible pigment which controls so many developmental responses of plants is demonstrated spectrophotometrically in intact corn coleoptiles and the spectra of intact lima bean seeds show spectral changes associated with germination processes.
