A subfamily of the small heat shock proteins of the marine red alga Neopyropia yezoensis localizes in the chloroplast.

ABSTRACT: Small heat shock proteins (sHSPs) play a crucial role under abiotic stress and are present in all organisms, from eukaryotes to prokaryotes. However, studies on the sHSP gene family in red alga are limited. In this study, we aimed to identify and characterize NysHSP genes from the genome of N. yezoensis, a marine red alga adapted to the stressful intertidal zone. We identified seven NysHSP genes distributed on all three chromosomes. Expression analysis revealed that all NysHSP genes responded to H₂O₂ and heat stress in the gametophytic thalli, but these genes responded only to heat stress in the sporophytic conchocelis. NysHSP20.3, which has an acidic isoelectric point (pI) and short N-terminal region, was localized as granules in the cytosol. Fluorescence imaging of
