Phototropism in light-grown mustard (sinapis alba l.) seedlings.

open access: yes, 1986
This thesis is an investigation of the mechanisms of blue-light- mediated phototropism in higher plants. Phototropism was analysed in light-grown mustard (Sinapis alba L.) seedlings under low pressure sodium (SOX) lamps to minimise the involvement of ...

How and why do roots sense light under the soil surface?

open access: yesFrontiers in Plant Science, 2015
Light can penetrate several centimetres below the soil surface. Growth, development and behaviour of plant roots are markedly affected by light despite their underground lifestyle.

A Portable Photocollector for the Field Collection of Insects in Biodiversity Assessment

open access: yesInsects
Arthropod biodiversity research usually requires large sample collections. The efficient handling of these samples has always been a critical bottleneck.

Phycomyces MADB interacts with MADA to form the primary photoreceptor complex for fungal phototropism [PDF]

open access: yes, 2009
The fungus Phycomyces blakesleeanus reacts to environmental signals, including light, gravity, touch, and the presence of nearby objects, by changing the speed and direction of growth of its fruiting body (sporangiophore).

Arabidopsis NPH1: a flavoprotein with the properties of a photoreceptor for phototropism.

open access: yes, 1998
The NPH1 gene of Arabidopsis thaliana encodes a 120-kilodalton serine-threonine protein kinase hypothesized to function as a photoreceptor for phototropism.

Phototropism: Translating light into directional growth [PDF]

open access: yes, 2012
Phototropism allows plants to align their photosynthetic tissues with incoming light. The direction of incident light is sensed by the phototropin family of blue light photoreceptors (phot1 and phot2 in Arabidopsis ), which are light-activated protein ...

The origin and evolution of phototropins

open access: yesFrontiers in Plant Science, 2015
Plant phototropism, the ability to bend toward or away from light, is predominantly controlled by blue-light photoreceptors, the phototropins. Although phototropins have been well-characterized in Arabidopsis thaliana, their evolutionary history is ...

Diagram explaining the interactions between gravitropism and phototropism in classical experiments dedicated to the study of gravitropism and phototropism.

open access: yes, 2019
A: In classical experiments, a plant is tilted from the vertical in order to study gravitropism. In this case, since the light is coming from the top, one side of the stem is shaded, which can induce a phototropic reaction. B: In classical experiments, a

Low Blue Light Enhances Phototropism by Releasing Cryptochrome1-Mediated Inhibition of PIF4 Expression.

open access: yes, 2020
International audienceShade-avoiding plants, including Arabidopsis (Arabidopsis thaliana), display a number of growth responses, such as elongation of stem-like structures and repositioning of leaves, elicited by shade cues, including a reduction in the ...

Ultrastructure and Spectral Characteristics of the Compound Eye of Asiophrida xanthospilota (Baly, 1881) (Coleoptera, Chrysomelidae)

open access: yesInsects
In this study, the morphology and ultrastructure of the compound eye of Asi. xanthospilota were examined by using scanning electron microscopy (SEM), transmission electron microscopy (TEM), micro-computed tomography (μCT), and 3D reconstruction. Spectral
