| Summary: | Organismal responses to environmental stresses are a determinant of the effect of climate change. These can occur through the regulation of gene expression, involving genetic adaptation and plastic changes as evolutionary strategy. Heat shock protein ( hsp ) family genes are extensively expanded and play important roles in thermal adaptation in oysters. We investigated expression of all heat-responsive hsp s in two allopatric congeneric oyster species, Crassostrea gigas and C. angulata , which are respectively distributed along the northern and southern coasts of China, using common garden and reciprocal transplant experiments. Our results showed that hsp s in C. gigas have evolved higher basal levels of expression under ambient conditions at each field site, with lower expression plasticity in response to heat stress in comparison to C. angulata , which exhibited lower baseline expression but higher expression plasticity. This pattern was fixed regardless of environmental disturbance, potentially implying ... |
