New crop loss study underscores urgent need for resistant varieties

February 25th, 2019 / Alliance for Science, US

Plant pests and diseases are significantly reducing yields of five major food crops across the globe, underscoring the critical need to develop new resistant varieties, according to a new study.

Some 137 pathogens and pests cause losses of 10 to 40 percent in the staple crops — wheat, maize (corn), soybeans, …

Study shows how plants use ‘baits’ to trap pathogens

February 28th, 2018 / Earlham Institute, UK

A study published in Genome Biology shows how plants use ‘baits’ to recognize and trap disease-causing pathogens before infection can start.
Ksenia Krasileva and her team from Earlham Institute, together with researchers from The Sainsbury Laboratory, used phylogenetic analyses to identify how these ‘bait’ genes are distributed throughout different wild and …

Fighting plant pests

February 14th, 2018 / Daily Monitor, Uganda

B4FA Fellow Michael Ssali writes:
Pests are described as insects, bacteria, viruses, birds, and rodents that destroy crops by eating them or by infecting them with diseases.
They are often a nuisance which results in huge losses for the farmer. They can damage the crop when it is growing in the field …

How plant sensors detect pathogens

August 26th, 2015 / Erika Alert, AAAS, US

An international team of scientists describes precisely how a plant senses a pathogen, bringing an unprecedented level of detail to Flor’s model. “We know that plants have sensors to detect pathogens but we knew little about how they work,” says Professor Banfield from the John Innes Centre (UK).
