Comparative Proteomic Analysis of Non-Bleached and Bleached Fragments of the Hydrocoral <i>Millepora complanata</i> Reveals Stress Response Signatures Following the 2015-2016 ENSO Event in the Mexican Caribbean.

ABSTRACT: The hydrocoral Millepora complanata (fire coral) plays a critical role in reef structure and relies on a symbiotic relationship with Symbiodiniaceae algae. Environmental stressors derived from climate change, such as UV radiation and elevated temperatures, disrupt this symbiosis, leading to bleaching and threatening reef survival. To gain insight into the thermal stress response of this reef-building hydrocoral, this study investigates the proteomic response of M. complanata to bleaching during the 2015-2016 El Niño event. Fragments from non-bleached and bleached colonies of the hydrocoral M. complanata were collected from a coral reef in the Mexican Caribbean, and proteomic extracts were analyzed using nano-liquid chromatography-tandem mass spectrometry (nano-LC-MS/MS
