Going underground: Benefits of phototropism in Arabidopsis depend on the soil environment [abstract] [PDF]

, 2004

Evolution of size and pattern in the social amoebas [PDF]

, 2007
A fundamental goal of biology is to understand how novel phenotypes evolved through changes in existing genes. The Dictyostelia or social amoebas represent a simple form of multicellularity, where starving cells aggregate to build fruiting structures ...

A method for the quantification of phototropic and gravitropic sensitivities of plants combining an original experimental device with model-assisted phenotyping: Exploratory test of the method on three hardwood tree species.

PLoS ONE, 2019
Perception of inclination in the gravity field and perception of light direction are two important environmental signals implicated in the control of plant shape and habit. However, their quantitative study in light-grown plants remains a challenge.

Magnetic field effects on plant growth, development and evolution

Frontiers in Plant Science, 2014
The geomagnetic field (GMF) is a natural component of our environment. Plants, which are known to sense different wavelengths of light, respond to gravity, react to touch and electrical signaling, cannot escape the effect of GMF.

The Effects of Water Stress and Apical Auxin Receptor Coverage on Phototropism in Arabidopsis thaliana [PDF]

, 2015
Arabidopsis thaliana was first grown in the environmental chamber. The water tray and soil were kept moist for all plants as seedlings. They were kept in16 hours light and 8 hours of dark condition until they developed 4 true leaves.

Phototropins maintain robust circadian oscillation of PSII operating efficiency under blue light [PDF]

, 2015
The circadian system allows plants to coordinate metabolic and physiological functions with predictable environmental variables such as dusk and dawn.

Abstracting Hopper

Textes & Contextes, 2019
One of the most seductive aspects of Hopper paintings is the sheer visual potency of their painted surface, the lavish formal trap of line and color that the artist has composed.

Selective gas detection using Mn3O4/WO3 composites as a sensing layer [PDF]

, 2019
Pure WO3 sensors and Mn3O4/WO3 composite sensors with different Mn concentrations (1 atom %, 3 atom % and 5 atom %) were successfully prepared through a facile hydrothermal method.

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

Frontiers 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.

Phototropism of Phycomyces Sporangiophores [PDF]

Nature, 1957
THE primary purpose of my previous communication1 was to show that the reversal of phototropism at about 300 mµ reported by Curry and Gruen2 is explicable in optical terms, and that it was not necessary to postulate a novel photochemical reaction occurring in the far ultra-violet.
