Action Spectra for the Inhibition of Hypocotyl Growth by Continuous Irradiation in Light and Dark-Grown Sinapis alba L. Seedlings.
Action spectra for the inhibition by continuous (24-hour) irradiation of hypocotyl growth in 54-hour-old Sinapis alba L. seedlings were measured using seedlings which had had four differentExpand
Phytochrome in Light-Grown Plants
It is convenient to divide the photomorphogenetic responses of both dark-grown and light-grown plants into two categories. The first is the so-called induction or end-of-day response which isExpand
Partial purification and peptide mapping of ubiquitin-phytochrome conjugates from oat
Phytochrome is rapidly degraded in vivo following photoconversion from the relatively stable red light absorbing form Pr to the far red light absorbing form Pfr. In etiolated seedlings from severalExpand
Red light-induced accumulation of ubiquitin-phytochrome conjugates in both monocots and dicots.
Phytochrome is rapidly degraded in vivo after photoconversion from the stable red-absorbing (Pr) form to the far red-absorbing (Pfr) form. Previously, we have shown in etiolated oat seedlings thatExpand
STIMULATION OF THE SHIBATA SHIFT BY PHOTOCHROME IN THE COTYLEDONS OF THE MUSTARD SEEDLING SINAPIS ALBA L.
Abstract— In the cotyledons of the mustard seedling Sinapis alba L. the duration of the Shibata shift can be greatly shortened by a pretreatment with light pulses prior to the protochlorophyllide–Expand
Effects of the herbicide san 9789 on photomorphogenic responses.
The herbicide, 4-chloro-5-(methylamino)-2-(alpha,alpha,alpha-trifluoro-m-tolyl)- 3(2H)-pyridazinone (San 9789), an inhibitor that prevents both carotenoid and chlorophyll accumulation and normalExpand
Spectrophotometric phytochrome measurements in light-grown Avena sativa L.
Phytochrome was studied spectrophotometrically in Avena sativa L. seedlings that had been grown for 6 d in continous white fluorescent light from lamps. Greening was prevented through the use of theExpand
PHOTOPHYSICAL PARAMETERS OF CHLOROPHYLLS a AND b·FLUORESCENCE AND LASER‐INDUCED OPTOACOUSTIC MEASUREMENTS
Abstract— The quantum yields of internal conversion (energy loss) of the photoexcited chlorophylls a and b in ethanol at 24°C have been determined by measuring the quantum yields of the competingExpand
Red light-induced formation of ubiquitin-phytochrome conjugates: Identification of possible intermediates of phytochrome degradation.
Phytochrome is the photoreceptor that controls red light-mediated morphogenesis in higher plants. It exists in two photointerconvertible forms, a red light-absorbing form, Pr, and a far-redExpand
Ubiquitin-phytochrome conjugates. Pool dynamics during in vivo phytochrome degradation.
The plant photoreceptor chromoprotein, phytochrome, is rapidly degraded in vivo after photoconversion from a stable red light-absorbing form (Pr) to a far-red light-absorbing form (Pfr). Previously,Expand
