PHI-base, the Pathogen-Host Interaction database is an open access internet resource which provides information on pathogenicity, virulence and effector genes from different pathogens, where the contribution of the genes to pathogenicity has been experimentally tested. In addition, at the request of the international community, negative results obtained from well designed and executed experiments have been included. PHI-base also provides information on commercially used drug targets and variant pathogen gene sequences which lead to drug-resistance / drug insensitivity.
Plant Biology and Crop Science
To carry out world-class plant biology and crop science research that delivers new knowledge, innovation and practices that will increase crop productivity and quality and develop environmentally sustainable solutions for food and energy production.
Research in PBCS contributes to our Institute themes:
- 20:20 Wheat®: Increasing wheat productivity to yield 20 tonnes per hectare in 20 years.
- Cropping Carbon: Optimising carbon capture by grasslands and perennial energy crops, such as Willow, to help underpin the UK's transition to a low carbon economy.
- Designing Seeds: Harnessing our expertise in seed biology and biochemistry to deliver improved health and nutrition through seeds.
- Sustainable Systems: Designing, modelling and assessing sustainable agricultural systems that increase productivity while minimising environmental impact.
The aim of our work is to identify and characterise genetic solutions for the control of take-all disease in wheat. Take-all is a serious root disease of wheat which is a major constraint during consecutive wheat cropping. The disease is caused by the soil dwelling ascomycete fungus Gaeumannomyces graminis var. tritici (Ggt) (Freeman & Ward, 2004). The fungus causes black necrotic lesions in the root tissue which restrict the uptake of water and nutrients from the soil (Figure 1).

Department Press Releases
In young plants, you can sometimes distinguish cultivated wheat varieties from wild species by their colour. Wild wheat appears either glossy green or a matte bluish-grey, but cultivated varieties are almost always the latter. The bluish-grey colour comes from a waxy film thought to increase yields and protect the plant from environmental stress, particularly drought and diseases. The genes that produce the coating have long eluded researchers, but work by an international team has now revealed them.
Professor Peter Shewry has received the Clyde H. Bailey medal in recognition of his research into the development, structures and composition of the wheat grain. His work at Rothamsted Research focuses on improving wheat quality for human health, particularly on enhancing fibre and phenolic acid content, and performance in milling and bread-making. The medal recognises outstanding achievements in the service of cereal science and technology.
The Indo-UK Centre for the improvement of Nitrogen use Efficiency in Wheat (INEW) was launched today at the Indian Institute of Wheat and Barley Research (ICAR-IIWBR, Karnal, Haryana, India). The centre will generate new types of wheat with improved use of nitrogen, which can be used in breeding programmes in both countries, carrying out a joint research programme, developing shared technologies and facilities and providing training opportunities for early career scientists.
Chloroplasts are important structures in plant cells that perform photosynthesis and mature from small precursors called plastids. Wheat, like many other plants, inherit their chloroplasts only from their mother via the egg cell. However, the mechanism that leads to this was not known. Scientists at Rothamsted Research and colleagues at the University of Manchester labelled plastids in wheat with a green fluorescent protein (GFP) and observed them in developing pollen grains. They show for the first time that plastids are degraded in mature sperm cells just prior to fertilization.
The model plant Arabidopsis, infected by Fusarium, is used to advance understanding of how Fusarium infects wheat.
As part of the Sustainable Agriculture Research and Innovation Club (SARIC), developed and funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the Natural Environment Research Council (NERC), together with industry partners, scientists at Rothamsted Research are soon to begin work on two major research projects.
Employment vacancies - Plant Biology and Crop Science
An exciting opportunity exists for a Post-Doctoral Research Scientist to work within the Wheat Pathogenomics team at Rothamsted Research on a Bilateral BBSRC-Embrapa (Brazil) project with the overall objective of assessing the use of Host Induced Gene Silencing (HIGS) to improve wheat resistance to Fusarium Ear Blight.
