Abstract excerpt

Climate-driven marine heatwaves (HW) are extreme, large-scale events characterized by elevated ocean temperatures lasting from days to months. Despite their importance, little is known about the molecular mechanisms of algal response to marine HW. Recent studies suggest that metacaspases play an important role in thermotolerance. Metacaspases are cysteine proteases structurally similar to caspases that are best...
