Temporal transcriptional rhythms govern coral-symbiont function and microbiome dynamics

Abstract

Diel rhythms align physiological processes with light/dark cycles, driving predictable oscillations in organismal activity. Here we examine diel transcriptional rhythms in coral-associated microeukaryotes, focusing on corallicolid apicomplexans. We identify extensive diel oscillations in gene expression in corallicolids and their coral hosts, providing insights into the temporal coordination of host-symbiont interactions in reef ecosystems.

My current research combination of molecular techniques (SSU rRNA amplicon sequencing), traditional culturing and microscopy, and imaging (fluorescence in-situ hybridization) will be used in an attempt to finally uncover the causative agents of various coral diseases.

My current research focuses on understanding the roles of micro-eukaryotes and bacteria in marine organisms. Initially, I will be researching the coral holobiont during bleaching from a single-cell perspective.
