Biological Chemistry and Crop Protection
Rothamsted Research scientists develop Camelina sativa plants that accumulate high levels of Omega-3 oils EPA and DHA in their seeds.
Rothamsted Research scientists discover the genetic mechanisms that allow aphids to adapt to a new host plant and provide natural resistance to neonicotinoid insecticides.
The European Commission has awarded a consortium of research organisations, including Rothamsted Research and companies, some €1 million ($1.4 million) to develop insecticide synergists for agricultural, household and public health use.
Rothamsted Research offers a post graduate award in Current Research in Crop Protection, as part of the BBSRC Advanced Training Partnerships Programme
Rothamsted Research scientists show that a natural plant activator can pre-dispose maize to produce "smells" that repel pests
Rothamsted Research scientists study the newly sequenced Ehux genes to make terrestrial sources of omega-3 fatty acids
The extension of the current trial will allow scientists to also study the effects of autumn aphid infestations on their experimental `aphid-repelling` wheat. A public consultation has begun.
‘Biological weapons’ and immunity in an invasive alien species
The harlequin ladybird (Harmonia axyridis) is a polyphagous alien invader in the UK, thought to pose a serious threat to natural enemy communities and the agro-ecosystem service they provide in terms of insect pest regulation. H. axyridis carries spores of obligate parasitic microsporidia, which are deadly pathogens for native ladybirds1. Intraguild predation is an important selective force amongst competing ladybird species, and it has therefore been hypothesised that H.
Electrostatic initiation of herbivore-induced signalling in crop plants
Understanding plant-insect interactions is vital for food security as they are key to food production (through pollination) and the prevention of food destruction (through herbivory). In both cases, the interactions depend on the perception of specific signals, such as plant volatiles and their modification by insect-plant interactions. A discovery in the labs of DR and HW has recently found that these interactions may be more sophisticated than previously thought1.
The biological and molecular factors influencing the control of two whitefly species (Bemisia tabaci and Trialeurodes vaporium) on different host plants
Background: Whiteflies are economically important insect pests. The two most prevalent are Glasshouse whitefly (Trialeurodes vaporariorum) and Silverleaf whitefly (Bemisia tabaci). Both are highly polyphagous and share many host plants.
New opportunities to understand human and insect ryanodine receptors through their differential interactions with novel chemical agonists
Ryanodine receptors (RyRs) are a class of ligand-gated calcium channels controlling the release of calcium from intracellular stores. These large trans-membrane receptors are predominantly localized on the sarcoplasmic reticulum within muscle cells.
Molecular characterisation of the N-end rule pathway- a protein degradation pathway of agricultural importance
Recently, we discovered that a pathway of targeted protein degradation- the N-end rule pathway-regulates ABA signalling and seed oil mobilisation (Holman et al., 2009 PNAS USA) and acts as a sensor for hypoxia (Gibbs et al., 2011 Nature). Others have shown important roles in leaf development and senescence (Graciet et al., 2011 TIPS). Thus this pathway has several functions of great importance for agriculture.
Research focuses on lipid metabolism and signalling, in particular on the mechanism and roles of lipid catabolism and the impact of these processes on plant physiology and lipid engineering.
The research of this group involves the detection/monitoring of resistance to existing and new pesticides and genetic and toxicological characterisation of resistance traits.
Chemical ecology research at Rothamsted exploits long established and acclaimed expertise in the identification and development of pheromones and other semiochemicals (signalling chemicals) for use in crop protection.
Post-Doctoral Research Scientist
Rothamsted Research, the largest agricultural research centre in the UK and the oldest agricultural research station in the world, is seeking an experienced molecular biologist/biochemist to join the Resistance group within the Department of Biological Chemistry and Crop Protection.
