Light as Stress Factor to Plant Roots – Case of Root Halotropism
Frontiers in Plant Science, 2014 Despite growing underground, largely in darkness, roots emerge to be very sensitive to light. Recently, several important papers have been published which reveal that plant roots not only express all known light receptors but also that their growth ...

Microbial drivers of root plasticity
New Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Plant Biology, Volume 27, Issue 6, Page 948-961, October 2025.Human‐invisible but bee‐visible UV patterns in flowers aid pollination by signalling to pollinators and protecting vulnerable DNA in pollen. ABSTRACT Ultraviolet light shining on flowers has various effects. In this review we assess functions of UV pigments and UV reflection patterns in flowers, including visual signalling by reflectance, fluorescence,

Role of Leaves in Phototropism [PDF]
Plant Physiology, 1966 Experiments with green seedlings of sunflower (Helianthus annuns L.) indicate the existence of a phototropic mechanism which involves the leaves or cotyledons, and which can produce an asymmetry of auxin content without the involvement of lateral auxin transport, the classic explanation of phototropism in etiolated seedlings.

Phytochrome A Mediates Blue-light Enhancement of Second-positive Phototropism in Arabidopsis
Frontiers in Plant Science, 2016 Hypocotyl phototropism of etiolated Arabidopsis seedlings is primarily mediated by the blue-light receptor kinase phototropin 1 (phot1). Phot1-mediated curvature to continuous unilateral blue light irradiation (0.5 µmol m-2 s-1) is enhanced by overhead ...

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.

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.

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.
