Light-dependent gravitropism and negative phototropism of inflorescence stems in a dominant Aux/IAA mutant of Arabidopsis thaliana, axr2 [PDF]
Journal of Plant Research, 2014 Gravitropism and phototropism of the primary inflorescence stems were examined in a dominant Aux/IAA mutant of Arabidopsis, axr2/iaa7, which did not display either tropism in hypocotyls.

Shoot phototropism in higher plants: New light through old concepts
American Journal of Botany, 2013 Light is a key environmental factor that drives many aspects of plant growth and development. Phototropism, the reorientation of growth toward or away from light, represents one of these important adaptive processes.

Shade Promotes Phototropism through Phytochrome B-Controlled Auxin Production
Current Biology, 2016 Phototropism is an asymmetric growth response enabling plants to optimally position their organs. In flowering plants, the phototropin (phot) blue light receptors are essential to detect light gradients.

Physiologia Plantarum, 1997 The role of phytochrome A (phyA) and phytochrome B (phyB) in phototropism was investigated by using the phytochrome-deficient mutants phyA-101, phyB-1 and a phyA/phyB double mutant.

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 ...

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 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.

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 as a Phenomenon of Inhibition
1980The concept of hormonal regulation of plant growth, gradually developed during the first quarter of this century, eventually led to the Cholodny-Went theory of tropistic movements. According to this theory the curving response of stems and roots to unilateral photo-and geotropic stimuli results from an uneven lateral distribution of auxin.
