Perception of long-chain N-acyl homoserine lactones in plants
Project
Project code: JKI-EP-08-2278
Contract period: 01.02.2016
- 31.01.2019
Purpose of research: Basic research
The ability to monitor the surroundings is for plant of crucial importance. Microorganism-derived molecules, effector proteins and bacterial quorum sensing molecules (QSM) trigger specific reactions in plant organism. QS molecules are usually used for cell-to-cell communication within bacterial populations. In plants, QSMs induce multiple reactions, for example N-3-oxo-tetradecanoyl-L-homoserine lactone (oxo-C14-HSL) synthesized by Sinorhizobium meliloti primes Arabidopsis and barley for enhanced defense: augmented callose deposition, accumulation of phenolic compounds, and lignification of cell walls. Furthermore, increased levels of oxylipins and salicylic acid favor stomatal closure in response to pathogen. Although much is know on AHL perception in bacteria (LuxR family) and animals (PPAR receptors and the IQGAP1 G-protein), the knowledge on AHL recognition in plants is still very poor. Our main goal in this project is to characterize AHL perception mechanism(s) in plants.
