UVR8 in Arabidopsis thaliana regulates multiple aspects of cellular differentiation during leaf development in response to ultraviolet B radiation. (2009)

Wargent, Jason J., Gegas, Vasilis C., Jenkins, Gareth I., Doonan, John H., Paul, Nigel D.

Responses specific to ultraviolet B (UV-B) wavelengths are still poorly understood, both in terms of initial signalling and effects on morphogenesis. Arabidopsis thaliana UV RESISTANCE LOCUS8 (UVR8)...

The aqueous photodegradation of fenitrothion under various agricultural plastics : implications for pesticide longevity in agricultural 'micro-environments'. (2009)

Weber, Jan, Halsall, Crispin J., Wargent, Jason J., Paul, Nigel D.

Plastic cladding is increasingly used in agriculture to create micro-environments to improve crop yield/growth. Many of these plastics can alter the solar light spectrum by inhibiting or reducing the...

Ultraviolet radiation as a limiting factor in leaf expansion and development. (2009)

Wargent, Jason J., Moore, Jason P., Ennos , A. Roland., Paul , Nigel D.

Reductions in leaf growth are a commonly observed response to ultraviolet radiation, but the underlying mechanisms remain poorly defined. This study examined the response of leaves exposed to a UV...

A comparative study on the aqueous photodegradation of two organophosphorus pesticides under simulated and natural sunlight. (2009)

Weber, Jan, Halsall, Crispin J., Wargent, Jason J., Paul, Nigel D.

Aqueous solutions of fenitrothion and methyl parathion were photochemically degraded in an Atlas Suntest solar simulator (500 W m-2) as well as under ambient sunlight at Lancaster University (June &...

Ultraviolet radiation as a limiting factor in leaf expansion and development. (2008)

Tri-trophic consequences of UV-B exposure: plants, herbivores and parasitoids. (2007)

Foggo, Andrew, Higgins, Sahran, Wargent, Jason J., Coleman , Ross A.

In this paper we demonstrate a UV-B-mediated link between host plants, herbivores and their parasitoids, using a model system consisting of a host plant Brassica oleracea, a herbivore Plutella...

Mechanisms of response to ultraviolet-b radiation — A whole plant perspective. (2007)

Wargent, Jason J., Paul, Nigel D.

Plant responses to ultraviolet (UV) radiation are numerous, resulting in rapid and permanent alteration to numerous aspects of plant form, physiology and biochemistry. Such responses to UV and UV-B...

Influence of UV-B Radiation and Temperature on Photodegradation of PAHs: Preliminary Results (2006)

Nadal, M., Wargent, Jason J., Jones, Kevin C., Paul, Nigel D., Schuhmacher, M., Domingo, J. L.

The joint impact of UV-B radiation and temperature on photodegradation of polycyclic aromatic hydrocarbons (PAHs) sorbed to an organic solvent was assessed in this study. This approach was...

Influence of UV-B radiation and temperature on photodegradation of PAHs : preliminary results. (2006)

Nadal, Martí, Wargent, Jason J., Jones, Kevin C., Paul, Nigel D., Schuhmacher, Marta, Domingo, José L.

The joint impact of UV-B radiation and temperature on photodegradation of polycyclic aromatic hydrocarbons (PAHs) sorbed to an organic solvent was assessed in this study. This approach was...

UV supplementation for growth regulation and disease control. (2006)

Wargent, Jason J., Taylor, A., Paul, Nigel D.

The benefits of supplementary ultraviolet radiation (UVB: 280-320nm) in protected lettuce were investigated in controlled environment studies. Exposure to UV-B prior to inoculation with a conidial...

The Use of Wavelength-selective Plastic Cladding Materials in Horticulture: Understanding of Crop and Fungal Responses Through the Assessment of Biological Spectral Weighting Functions (2005)

Nigel D. Paul, Rob J. Jacobson, Anna Taylor, Jason J. Wargent, Jason P. Moore

Plant responses to light spectral quality can be exploited to deliver a range of agronomically desirable end points in protected crops. This can be achieved using plastics with specific spectral...
