Does rust-free rice hold the secret?

All cereals, except rice, are susceptible to rust. Wheat, maize, barley, millet, triticale, and oats all get rust. The spores of rust fungi land on a host plant, germinate, and grow toward a stomatal pore on the leaf surface to initiate infection. Rust infections produce red or yellow pustulating spores that give infected plants a…

Hessian fly heading for the sack

strawb
Wheat crops suffer millions of dollars’ worth of damage each year due to the hessian fly, Mayetiola destructor. The most effective control method is genetic resistance, when wheat resistance genes cause death of the attacking larvae by activating a defense response against avirulent hessian flies. Unfortunately this has led to flies that can overcome resistant…

Fast but furious: High yielding plants linked to poor pest resistance

strawb
Breeding plants for fast growth and high yield may make them more susceptible to pests and diseases. New research from the University of Zurich using the model plant Arabidopsis thaliana has confirmed long suspected theory, showing that when plants put more resources into growth they often shut down some defence genes.
