The same hormone that helps plants survive heat stress might protect coral reefs from bleaching.

Hypothesis 6: Dark Priming / SNAT Biomarker -- Nocturnal Melatonin Failure Under Nighttime Warming (H6-009-C1)

Warmer nights may stop corals from producing a crucial stress-shield hormone, accelerating bleaching.

Target: Plant Melatonin Stress Biology x Coral Bleaching / Symbiodiniaceae Thermal Tolerance

Could the same hormone that helps plants survive stress also protect coral reefs from bleaching?

Summary Table
