Researchers identify a receptor that boosts plant immunity against pests and diseases [Registered]

A team of international researchers has uncovered a mechanism by which plants are able to better defend themselves against disease-causing pathogens. The work, led by Dr Jurriaan Ton and Dr Estrella Luna at the University of Sheffield, has identified the key receptor binding a chemical called BABA (β-aminobutyric acid) which is boosting plant immunity. BABA has long been known for its protective effects against devastating plant diseases, such as potato blight, but has so far not been used widely in crop protection because of undesirable side effects. “We have found that the plant receptor binding BABA is an ‘aspartyl tRNA…
