HSP mRNA sequences and their expression under different thermal oscillation patterns and heat stress in two populations of Nodipecten subnodosus.

ABSTRACT: Understanding the molecular mechanisms underlying thermal acclimation and heat shock responses in marine ectotherms is critical for assessing their adaptive capacity in the context of climate change and climate extremes. This study examines the expression dynamics of heat shock proteins (HSPs) in the scallop Nodipecten subnodosus, shedding light on their role in thermal adaptation. Our analysis revealed the presence of several conserved functional signatures in N. subnodosus HSPs deduced amino acid sequences. Comparative gene expression profiling between two populations of N. subnodosus, maintained for 15 days under constant and oscillatory thermal regimes and then exposed to acute heat stress, revealed conserved adaptive traits. The heat-inducible nature of N. subnodosus HSP70 (HSPA8) gen
