Developing transcriptional profiles in Orbicella franksi exposed to copper: Characterizing responses associated with a spectrum of laboratory-controlled environmental conditions

- Cnidarian responses to copper exposure expanded by 52 additional genes.
- 29 time-dependent responses, 44 concentration-dependent responses.
- 5 genes responsive to concentration, time, and interactions.
- Hormesis is evident in 0.3 ppb treatment.
- Cu2+ impacts development, immunity, bulk transport, Ca2+ flux, mitochondria, & ECM.
