Rice blast: crop blighter.
Inhibiting one protein
stops the fungal spread.
Up to 30% of rice crop is destroyed by rice blast every year, causing huge welfare and economic costs. Sakulkoo et al (2018) have found that inhibiting a single protein enzyme in the fungus stops the spread of the blight through a rice plant.
The fungus’s mitogen-activated protein Pmk1 plays a role in suppressing its host’s immune system and controls the ability of the fungus to move from one rice cell to another. By inhibiting Pmk1’s kinase the fungus is trapped within the infected rice cell and is unable to spread and infect the rest of the rice plant. This latest discovery could point the way towards new rice blast control methods, resulting in increased food security and economic development.
