Seven housekeeping genes were tested for expression stability during two abiotic stresses.
Thermal and pH stress-specific sets of HKGs are proposed as RGs for qPCR in Sinularia.
ACTB, RPL12, SRP54 and TUBB genes were found most stable in a stress-dependent manner.
TUBA and EF1A were found unsuitable for use as reference genes.
Stress-dependent differential expression of HSP70 gene was detected.
