The 11-hydroxy-jasmonic acid pathway expands jasmonate catabolic repertoire for stress-specific hormone attenuation in Arabidopsis
In Arabidopsis plants, one enzyme family makes a different breakdown product of a stress hormone than scientists thought.
Thierry Heitz, Valentin Marquis et al.
Plants make a stress hormone that shifts their energy from growing to defending. This hormone must be broken down at the right time, or its defense signal lasts too long. Scientists in this study found that one set of plant enzymes makes a different breakdown product than experts had assumed for years. The plant uses one breakdown path after a physical wound and a different path after a fungal infection.
Shows the plant uses different chemical routes depending on whether it is wounded or infected.
Lab plant only, no crop or human relevance shown yet.
