"This is the first step to achieving more durable resistance to a devastating disease in wheat," said Dr Cristobal Uauy, co-author of the report, recently appointed to the John Innes Centre in Norwich.
Resistance to stripe rust has previously been achieved using genes that are specific to single races of the disease. Unfortunately, each of these genes has had limited durability in the field because the pathogen has mutated to overcome them.
In the paper to be published in Science Express tomorrow, the international team of scientists report finding a novel type of gene in wild wheat that is absent in modern pasta and bread wheat varieties.
"This gene makes wheat more resistant to all stripe rust fungus races tested so far," said Dr Uauy.
The gene confers resistance at relatively high temperatures, and a focus of Dr Cristobal Uauy's research at JIC will be to test how effective it is in UK-adapted varieties.
Bread wheat provides about 20 per cent of the calories eaten by humankind and is the UK's biggest crop export.
Dr Uauy has recently been appointed at JIC. He will lead a research collaboration with the National Institute of Agricultural Botany (NIAB) designed to deliver practical benefits to agriculture. Research results will be made available to breeders, so they can be deployed into modern varieties for farmers.
Dr Uauy will use the latest genomic techniques to find genes in wheat that directly affect yield and nutritional content.
Yield is a complex trait influenced by many environmental and genetic factors. It was thought that the genetic component determining yield was made up of many different genes each exerting a small influence, but recent work led by the John Innes Centre has challenged this view. Several stretches of the genome, known as quantitative trail loci (QTLs) have been identified that exert large effects on yield, in different environments. Dr Uauy will lead the effort to find the precise genetic basis for their effect on yield.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
