Standard modern farming techniques rely on the heavy use of pesticides to improve crop yields, but many cause adverse effects, both to the consumer and to the environment. Bacteria can be used as environmentally friendly alternatives to pesticides, to improve plant growth and even to limit plant disease. However, few bacteria have been registered for such plant disease control, and at present none are from the new genus Paraburkholderia, which contains talented plant-beneficial bacteria with wide-ranging disease control abilities.
We propose to bioprospect in the plant microbiome for bacteria that live inside and on the surface of plants, particularly those from the genus Paraburkholderia, that can protect against important agricultural pathogens, focusing on those that cause fire blight, fungal diseases and potato late blight. Our aim is to identify new bacterial biocontrol agents, to expand the scope for biocontrol in agriculture.
Was ist das Besondere an diesem Projekt?
Our strategy will involve isolating strains from crop plants and testing their potential to control our target diseases, as well as testing already isolated bacteria for such abilities. Paraburkholderia strains that show promise will be characterised and tested in plants for their efficacy in preventing disease. This project aims to identify strains that can confer long-term resistance to pathogens, directly at the site of infection. To this end, the means of treatment with the potential bacterial biocontrol agent will be fitted to the particular crop to be protected; seed inoculation for the fast-growing crops maize and tomato, and spraying the mature tree to protect apple crops.
As our bacteria will be isolated from crop plants, they should already be part of the human diet, and therefore should not cause any ill effects to the consumer.
We will begin this project in February 2019 by screening our large in-house collection of bacteria for their ability to inhibit/ kill the three disease-causing agents, Fusarium solani, Phytopthora infestans and Erwinia amylovora. We will simultaneously begin to isolate strains from crop plant microbiomes, using specific media to enrich for the desired type of bacteria (the Paraburkholderia).
