Scientists have tested a new way to protect crops from a widespread and devastating bacterial disease, without using environmentally damaging chemical sprays.
An interdisciplinary team at the University of Glasgow have revealed a new method that could protect many important crop species against the common crop bacteria Pseudomonas syringae (Ps).
Ps and related bacterial species attack a wide variety of important crops in the UK and worldwide, including tomato, kiwifruit, peppers, olive, soybean and fruit trees, causing huge economic losses. Plant diseases are responsible for the loss of about 15% of world crops (worth $150 bn annually), of which a third is caused by bacteria such as Ps. The Ps species complex consists of over 50 known variants, which are responsible for diseases like blight, spot and bacterial speck. Once the bacteria infect part of a crop, the disease can spread rapidly because of the lack of genetic diversity in commercial crop varieties.
