UK & USA scientists collaborate to design crops of the future

UK & USA scientists collaborate to design crops of the future

Three projects to transform future farming while reducing pollution and energy inputs: Engineering synthetic relationships between plants and bacteria The quest to solve the mystery of the lost bacteria Developing a synthetic nitrogen-fixing factory within plant’s cells Three teams of UK and USA researchers will begin a programme of novel research to revolutionise current farming [...]

Stockholm University presents Honorary Doctorate to JIC scientist

Professor Ray Dixon has been presented with an honorary doctorate by Stockholm University. Professor Dixon received this honour in recognition of his four decades of research into the regulation of gene expression, focussing particularly on the genes that control nitrogen fixation in bacteria. Nitrogen fixation is a crucial step in the nitrogen cycle, making inert [...]

JIC receives a share of £20M investment for UK Synthetic Biology research

[Department for Business, Innovation and Skills press release] Professor Giles Oldroyd of the John Innes Centre has been awarded £2.5M from the Biotechnology and Biological Science Research Council (BBSRC) to begin developing cereal crops that can ‘fix’ their own nitrogen, making their own fertiliser. This is part of £20M of funding for synthetic biology projects [...]

Plant interaction with friendly bacteria gives pathogens their break

In two papers to be published in Current Biology, researchers from JIC and The Sainsbury Laboratory on the Norwich Research Park, and Rothamsted Research and the University of York identify genes that help plants interact with microbes in the soil. Professor Giles Oldroyd of the John Innes Centre explains how plant roots form beneficial interactions [...]

Major investment to persuade bacteria to help cereals access nitrogen from the air

The John Innes Centre will lead a $9.8m research project to investigate whether it is possible to initiate a symbiosis between cereal crops and bacteria. The symbiosis could help cereals access nitrogen from the air to improve yields. The five-year research project, funded by the Bill & Melinda Gates Foundation, could have most immediate benefit [...]

Legumes give nitrogen-supplying bacteria special access pass

Proceedings of the National Academy of Sciences of the U.S.A.

A 120-year debate on how nitrogen-fixing bacteria are able to breach the cell walls of legumes has been settled. A paper to be published on Monday 19th December by John Innes Centre scientists reports that plants themselves allow bacteria in. Once inside the right cells, these bacteria take nitrogen from the air and supply it [...]

New research may reduce global need for nitrogen fertilizers

New research may reduce global need for nitrogen fertilizers

Research published today in the journal Nature reveals how scientists at the John Innes Centre (JIC), Norwich and Washington State University, USA have managed to trigger nodulation in legumes, a key element of the nitrogen fixing process, without the bacteria normally necessary. This is an important step towards transferring nodulation, and possibly nitrogen fixation, to non-legume crops [...]
