Symbiodinium: the evolutionary transition to coral reef symbiont

点击翻译按钮获取中文摘要

Coral reefs are sustained by symbiosis between the coral host and dinoflagellates of genus Symbiodinium. Breakdown of this symbiosis under environmental stress results in coral bleaching and eventual death. This project aims to understand how dinoflagellate genomes have evolved to support a symbiotic lifestyle. The project aims to sequence genomes of Symbiodinium from reef corals and other hosts, and two free-living relatives. This should enable the identification of genes that have been gained or lost, or are under adaptive selection. This genome-scale perspective on the molecular systems implicated in the evolution of this symbiotic lifestyle has potential to inform strategies for preserving Australia's Great Barrier Reef in the face of climate variations.
