Protecting plants from stealthy diseases

Stealthy diseases sometimes trick plants by hijacking their defense signaling system, which issues an alarm that diverts plant resources for the wrong attack and allows the enemy pathogens to easily overrun plants.

Caterpillar deceives corn plant into lowering defenses against it

In a deception that likely has evolved over thousands of years, a caterpillar that feeds on corn leaves induces the plant to turn off its defenses against insect predators, allowing the caterpillar to eat more and grow faster, ...

Plants detect bacterial endotoxin in similar process to mammals

Similar to humans and animals, plants possess an innate immune system that protects them from invading pathogens. Molecular structures that only occur in pathogens enable their recognition and trigger the immune response. ...

Research paves way for new generation of fungicides

Plants that come under attack from pathogens have an automatic immune response. Fungi get around this plant immunity by injecting proteins into the host plant cells. These 'effector proteins' enable the fungi to escape the ...

Device speeds concentration step in food-pathogen detection

(Phys.org) —Researchers have developed a system that concentrates foodborne salmonella and other pathogens faster than conventional methods by using hollow thread-like fibers that filter out the cells, representing a potential ...

'Fountain of youth' for leaves discovered

What plant scientists call senescence, consumers experience as wilted produce and overripe fruit. A team led by Cornell horticulture professor Su-Sheng Gan has identified an enzymatic fountain of youth that slows the process ...
