Photochemistry and Photobiology, 1964
Summary Phototropic curvature is seen to varying degrees in all green plants from algae to orchids, and especially in seedlings, where it may assume life‐or‐death importance. It also occurs in a number of fungi. Recent work centers on the photorecptor, its action spectrum, the effector mechanism, and the inter‐relationships with normal growth.The ...

Angewandte Chemie International Edition in English, 1970
AbstractPhototropic glass darkens on exposure to light and returns to its original state in the absence of light. The most extensively investigated of these glasses contain grains of silver halide having sizes > 50 Å. A discussion of theoretical principles is followed by a review of the very broad scope of the phenomenon.

AbstractPhototropes Glas ändert seine Lichtdurchlässigkeit reversibel entsprechend der Lichteinwirkung. Die Phototropie dieser Gläser wird von den Silberhalogenid‐Partikeln bestimmt, die in der Größenordnung von >50 Å in homogener Verteilung im Glas ausgeschieden werden.

Phototropism in Conidiobolus Coronatus
Mycologia, 1973The phototropic responses of Conidiobolus coronatus (Cost.) Batko have been investigated with an emphasis on the responses of the secondary conidiophore.

This paper illustrates the thesis research and process that led me to conceive, design and evaluate the Phototropic Memories device, a novel interface supporting the intimate sharing of personal visual memories over spatial and temporal distance, between two emotionally bound persons.

PHOTOTROPISM OF COPROPHILOUS ZYGOMYCETES
Annual Review of Biophysics and Bioengineering, 1977Biological cells sense and react to their environment. This is as true for a neuron in the brain as for a bacterium in the intestine or a coprophilous Zygomycete on dung. To understand these cells on a molecular level scientists have choosen particu lar systems for extensive study. Such a system must respond to measurable stimuli, give clear responses,

Blue light is used as a source of information on the environment by all kind of living beings, from microbes to animals. The Zygomycete fungus Phycomyces blakesleeanus is notorious for the variety of responses to blue light, various invisible radiations, and other stimuli. The copious literature on the behaviour of Phycomyces accumulated over more than

Electrophysiology and Phototropism
2006Plants continually gather information about their environment. The conduction of bioelectrochemical excitation is a fundamental property of living organisms. Cells, tissues, and organs transmit electrochemical signals over short and long distances. The sensitive membranes in phloem cells facilitate the passage of electrical excitations in the form of ...
