Role of nitrogen in the photoinduction of protoperithecia and carotenoids in Neurospora crassa
Planta, 1987Nitrogen, as KNO3 or NH4NO3, can inhibit the photoinduction of protoperithecia in Neurospora crassa when present in the medium at a high concentration but does not inhibit the photoinduction of carotenoids. The point at which the presence of high nitrogen levels is no longer inhibitory is 5 h after illumination.

Photoinduction of arginine decarboxylase activity in leaves of Pharbitis nil
Phytochemistry, 1998The activity of arginine decarboxylase (ADC) in leaves of Pharbitis nil was induced by light. The ADC activity increased to a maximum 1 h after illumination, followed by a gradual decrease. This suggested light either induced synthesis of ADC protein de novo or was involved in its activation.

Morphogenesis in Trichoderma: Photoinduction and RNA
Developmental Biology, 1967Abstract 1. 1. Trichoderma viride cultured in petri dishes will sporulate if given a short illumination after reaching a certain level of maturation. 2. 2. Sporulation can be suppressed by fluorouracil (FU) and azaguanine given for short periods before or after photoinduction without affecting growth. 3. 3.

Photoinduction of anisotropic grains in organic compounds
Applied Optics, 1998We report the linear polarized light-induced anisotropic grains in azo-dye-colored gelatin films. The optical axes of the grains (fast or slow) are directed along the polarization vector of the exciting light.

Photoinduction of plastids and of chlorophyll in a Chlorella mutant
Journal of Cell Science, 1967ABSTRACT Stage-characterized populations of dark-grown heterotrophs of an asexually reproducing, unicellular alga, Chlorella mutant C-10, have been studied to determine light-induced ultra-structural changes in plastids and in chlorophyll synthesis.

Hologram record by means of film anisotropy photoinduction
Applied Optics, 1992The diffraction efficiency of a hologram in crossed polarizers, recorded by means of photoinduction of the optical anisotropy in a film with a different orientation of the polarization planes of interfering plane waves, is studied. The dependence between the diffraction efficiency of the hologram and the angle of orientation against the optical axis of

On the mechanism of photoinduction of carotenoid synthesis
Biochimica et Biophysica Acta (BBA) - Specialized Section on Biophysical Subjects, 1964Abstract 1. The photoinduced carotenogenesis of a species of mycobacteria consists of a photoinductive reaction followed by certain metabolic reactions that result in greatly enhanced carotenoid synthesis. 2. The action spectrum of photoinduction was found to have maxima at 365 mμ and 460 mμ, separated by a minimum region at 395 mμ.

IN VIVO PHOTOINDUCTION OF METALLOTHIONEIN IN HUMAN SKIN BY ULTRAVIOLET IRRADIATION
The Journal of Pathology, 1996The aims of this study were to confirm and substantiate the in vivo cutaneous induction of metallothionein (MT) in human skin by UVR, which we have reported in brief previously, and to make a preliminary attempt to characterize the time course of this phenomenon.

Pyrimidine Dimers: Effect of Temperature on Photoinduction
Science, 1966Ultraviolet-induced pyrimidine dimer formation in DNA and polyuridylic acid was inhibited on irradiation at 77°K. Enhancement of thymine dimer formation in solutions of DNA occurred upon addition of ethylene glycol. Low temperature measurements of absorbance of polyuridylic acid at low temperature showed that no significant alteration of the residues ...
