Figure S4 Visualized coral bleaching upon acute heat stress with or without the addition of venetoclax, Bcl-2 inhibitor. Non-preconditioned (NPC) corals bleach in both conditions but preconditioned (PC) corals show acquired higher thermal resilience that is lost after the addition of venetoclax. It points to the crucial role of pa-Bcl-2 in coral acclimatization and bleaching.
