Description

Coronatine is a phytotoxin produced by the bacterial pathogen Pseudomonas syringae. It is a complex molecule with a unique structure consisting of a cyclopropyl fatty acid moiety linked to a 3-hydroxy-2-pyridone ring system. This structure allows coronatine to mimic the action of jasmonates, a class of plant hormones involved in defense responses and growth regulation.

Coronatine disrupts plant defense mechanisms by suppressing jasmonate signaling pathways. This suppression leads to increased susceptibility to pathogens and pests, including insects and fungi.

Researchers study coronatine to understand its role in plant-pathogen interactions and to develop new strategies for controlling plant diseases.

For example, knowledge about coronatine's biosynthesis and mode of action could lead to the development of inhibitors that block its production or activity.

Furthermore, coronatine's ability to suppress jasmonate signaling has implications for plant growth and development, making it a potential tool for manipulating plant responses to environmental stresses.'
