Rice Blast Research A Step Closer To Controlling Devastating Crop Diseases
2013-06-18 11:57:00

University of Exeter Like a stealthy enemy, blast disease invades rice crops around the world, killing plants and cutting production of one of the most important global food sources. Now a study by an international team of researchers has shed light on how the rice blast fungus, Magnaporthe oryzae, invades plant tissue. The finding is a step towards learning how to control the disease, which by some estimates destroys enough rice to feed 60 million people annually. The team, from the...

More than 600 million people could be fed each year by halting the spread of fungal diseases in the world's five most important crops, according to research published today in the journal Nature. Furthermore, data reviewed by scientists suggests that in 70% of cases where infectious disease causes the extinction of a type of animal or plant, an emerging species of fungus is behind the problem. Evidence suggests this figure is increasing. The scientists behind the study, from the...

U.S. Department of Agriculture (USDA) scientists have characterized the molecular mechanism behind some plants' ability to resist rice blast, a fungal disease that affects cereal grain crops such as rice, wheat, rye and barley and can cause yield losses of up to 30 percent. The fungus has been found in 85 countries worldwide, including the United States. Agricultural Research Service (ARS) plant pathologist Yulin Jia at the agency's Dale Bumpers National Rice Research Center in Stuttgart,...

WEST LAFAYETTE, Ind. - Efforts to halt a fungus that deprives about 60 million people a year of food have led Purdue University scientists to discover the molecular machinery that enables the pathogen to blast its way into rice plants. The fungus, Magnaporthe grisea, which is known as rice blast fungus, is the most deadly of the pathogens that attack rice, reducing yields by as much as 75 percent in infected areas. Learning how the fungus tricks rice's natural defenses against pathogens to...

PARIS (AFP) -- Scientists have unravelled the genome of the rice plant's greatest fungal menace, a harvest-wrecking foe that each year destroys the potential to feed 60 million people. Magnaporthe grisea is the first pathogenic plant fungus to have its genetic code unravelled, a feat that the researchers hope will open the way to newer, smarter and less damaging weapons against this menace. M. grisea, also called rice blast, comprises windborne spores that stick to the leaves of the rice...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
