Symbiotic partnership between algae and animals that powers coral reefs

点击翻译按钮获取中文摘要

This project aims to unlock the molecular basis of a partnership between a microscopic plant and an animal that powers coral growth. Most corals depend on microscopic algae living inside their bodies to nourish them. Most corals have to recruit new algae each time they reproduce, but only a particular strain of algae is accepted. This project aims to establish how anemones and corals identify and take in the right alga, how the alga gives them food, and how the animal hosts regulate growth of their algae to optimise food production but avoid being overrun by algae. Understanding the partnership that drives reef growth and survival may better equip us to protect this threatened resource.
