Functional analysis of various conserved domains of NPH3 involved in phototropism in Arabidopsis thaliana [PDF]

open access: yes, 2008
only availablePhototropism - the directional growth (curvature) for a plant towards light, is a very important adaptive response in plants in order for them to maximize photosynthesis.

Higher plants use LOV to perceive blue light. [PDF]

open access: yes, 2008
Higher plants use several classes of blue light receptors to modulate a wide variety of physiological responses. Among them, both the phototropins and members of the Zeitlupe (ZTL) family use light oxygen voltage (LOV) photosensory domains.

Phototropic Curvature in Phycomyces [PDF]

open access: yesThe Journal of General Physiology, 1962
The distribution of curvature and of bending speed along the cell's growing region are studied during steady state phototropic bending. At the start, elemental bending speed parallels the known axial distribution of growth rate. Hence regional phototropic sensitivity is initially determined by the local growth rate, and unilateral visible light acts ...

Gravitropic Gene Expression Divergence Associated With Adaptation to Contrasting Environments in an Australian Wildflower

open access: yesMolecular Ecology, Volume 34, Issue 15, August 2025.
ABSTRACT Plants adapt to their local environment through complex interactions between genes, gene networks and hormones. Although the impact of gene expression on trait regulation and evolution has been recognised for many decades, its role in the evolution of adaptation is still a subject of intense exploration.

Light as Stress Factor to Plant Roots – Case of Root Halotropism

open access: yesFrontiers 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 ...

Differential gene reactions reveal drought response strategies in African acacias

open access: yesThe Plant Journal, Volume 123, Issue 3, August 2025.
SUMMARY Drought tolerance involves a complex series of genetic reactions that expand over time as water stress intensifies. We investigated gene expression reactions over 43 days of drought stress in two widespread African savanna trees: the umbrella acacia (Vachellia tortilis) and the splendid thorn acacia (Vachellia robusta).

The Alpha-Helix Concept: Innovative utilization of the Space Station Program. A report to the National Aeronautical and Space Administration requesting establishment of a Sensory Physiology Laboratory on the Space Station [PDF]

open access: yes
A major laboratory dedicated to biological-medical research is proposed for the Space Platform. The laboratory would focus on sensor physiology and biochemistry since sensory physiology represents the first impact of the new space environment on living ...

Harley's Course—Integrating Teachings From Western and Indigenous Sciences in an Undergraduate Biology Course

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
This paper describes a relational land‐based learning experiential field course that bridges Western and Indigenous scientific worldviews. We describe the impact of incorporating traditional Indigenous paradigms and knowledge into post‐secondary science curriculum and the challenges inherent in decolonizing Western science.
