Summary: Novel technologies are being sought to replace the traditional pesticides used to protect plants, particularly edible plants such as cereals. A new project is shedding light on the efficacy of environmentally friendly RNA-based vaccines that protect plants from diseases and pests.

Novel technologies are being sought to replace the traditional pesticides used to protect plants, particularly edible plants such as cereals. A new collaborative project between the University of Helsinki and the French National Centre for Scientific Research (CNRS) is shedding light on the efficacy of environmentally friendly RNA-based vaccines that protect plants from diseases and pests.

Plant diseases and pests cause considerable crop losses and threaten global food security. The diseases and pests have traditionally been fought with chemical pesticides, which spread throughout our environment and may be hazardous to human health, beneficial organisms and the environment.

“A new approach to plant protection involves vaccinating plants against pathogens with double-stranded RNA molecules that can be sprayed directly on the leaves,” explains Dr Minna Poranen of the Molecular and Integrative Biosciences Research Programme at the University of Helsinki’s Faculty of Biological and Environmental Sciences.The vaccine triggers a mechanism known as RNA interference, which is an innate defence mechanism of plants, animals and other eukaryotic organisms against pathogens. The vaccine can be targeted to the chosen pathogen by using RNA molecules which share sequence identity with the pest’s genes and prevents their expression…
