Abstract

Although the symbiotic partnership between corals and algal endosymbionts has been extensively explored, interactions between corals, their algal endosymbionts and microbial associates are still less understood. Screening the response of natural microbial consortiums inside corals can aid in exploiting them as markers for dysbiosis interactions inside the coral holobiont. The coral microbiome includes archaea, bacteria, fungi, and viruses hypothesized to play a pivotal vital role in coral health and tolerance to heat stress condition via different physiological, biochemical, and molecular mechanisms. The dynamic behaviour of microbial associates could denote their potential role in coral adaptation to future climate change, with microbiome shifts occurring independently as a response to thermal stress or as a response to host stress response. Associated adaptations include regulation of coral-algal-microbial interactions, expression of heat shock proteins, microbial composition changes, and accumulation of secondary metabolites to aid in sustaining the coral's overall homeostasis under ocean warming scenarios.
