Field pathogenomics a defence against rust and other "cereal killers"

With the announcement that ‘Kranich’ yellow rust race has been detected in the UK for the first time, together with an increase in fungal infection among previously resistant varieties, a new approach to disease management and prediction, Field Pathogenomics, is to be welcomed. It is one of the promising new methods to be discussed at forthcoming Agri-Tech East Pollinator “Rusts and other...

Study identifies 5 chemicals that trigger rice plants to fend off common pest

Chemical triggers that make plants defend themselves against insects could replace pesticides, causing less damage to the environment. New research published in Bioorganic & Medicinal Chemistry Letters identifies five chemicals that trigger rice plants to fend off a common pest – the white-backed planthopper, Sogatella furcifera. Pesticides are used around the world to control...

Field Scanalyzer installed at Rothamsted Research to revolutionise monitoring of crop growth and health

A world first for automated measuring of crop growth and health in the field was installed for Rothamsted Research in 2015 by LemnaTec GmbH. This is the world’s largest and most sophisticated facility built today and will revolutionise the way that crop health and growth are monitored in the field. The development of the facility has been supported by Rothamsted Research and BBSRC. The...

Researchers show that plants exposed to bacteria activate their immune system using three separate mechanisms

Spring is just around the corner and for many of us that means planting a garden with plenty of fruits and vegetables, including tomatoes. However, some of the plants will be infected by bacteria, leading to stunted growth and less nutritional value. Now, a University of Missouri research team has uncovered new regulations of defense pathways for plants. This discovery could lead to helping...

Aggressive plant fungus could pose threat to wheat production in UK

The spread of exotic and aggressive strains of a plant fungus is presenting a serious threat to wheat production in the UK, according to research published in Genome Biology . The research uses a new surveillance technique that could be applied internationally to respond to the spread of a wide variety of plant diseases. Wheat is a critical staple and provides 20% of the calories and...

Scientists find potential way of controlling leaf blotch disease in wheat

Scientists have found a genetic mechanism that could stop the spread of a "devastating" disease threatening wheat crops. Septoria leaf blotch (STB) is caused by a fungus and is seen as the most significant threat to wheat yields in Europe, and most other wheat growing regions, as currently available fungicides become less effective against resistant strains of the disease. ...

Researchers unveil new way in which plants perceive pathogens to activate immunity

Scientists at The Sainsbury Laboratory in Norwich, with collaborators at Michigan State University and the University of Illinois, have unveiled a new way in which plants perceive pathogens to activate immunity. They also show how pathogens inhibit the mechanism to cause disease. It was previously only associated with other processes in mammalian cells. When plants detect microbial...

Developing new methods to assess resistance to disease in young oilseed rape plants

Being able to measure resistance to disease in young oilseed rape plants is vital in the battle to breed new disease resistant varieties of the crop, and is the focus of a study by a team of researchers led by the University of Hertfordshire. Oilseed rape is prone to phoma stem canker, also known as blackleg disease, which is responsible for losses worth more than £1,200 million in...

ATP receptors help plants manage environmental change, pests and wounds

ATP (adenosine triphosphate) is the main energy source inside a cell and is considered to be the high energy molecule that drives all life processes in animals and humans. Outside the cell, membrane receptors that attract ATP drive muscle control, neurotransmission, inflammation and development. Now, researchers at the University of Missouri have found the same receptor in plants and believe...
