Heat map depicting the expression of immune genes of adult
infected with OsHV-1,
LGP32. The expression of each target gene was normalised to the transcript level of control groups (adults injected with sterile seawater) at each sampling time point (1, 2, 3 and 4 days post-injection). Adult oysters in the early stages of OsHV-1 infection (A2) cluster separately to adult oysters in the early (A3) and late (A4) stages of Vibrio infection. Hierarchical clustering did not reveal a distinction in the transcriptional response of adult C. gigas infected with V. aestuarianus or V. tasmaniensis LGP32.
