Mark Waters

Originating from the UK, Dr Mark Waters joined the University of Western Australia in 2010 to work on the genetics of karrikin responses in Arabidopsis. Derived from burnt plant matter,karrikins are seed germination stimulants that resemble strigolactone hormones. Dr Waters’ research has elucidated early events in karrikin and strigolactone signalling, specifically involving the karrikin receptor protein KAI2. His work has established that KAI2 regulates diverse aspects of the plant life cycle, and may be a receptor for an unknown plant hormone. Evolutionary conservation of KAI2 suggests that KAI2-dependent signalling is a fundamental and ancient process common to all plants.
