Differential expression of GIMAP genes upon induction of apoptosis and autophagy suggests a potential role in cnidarian symbiosis and disease.

Coral reefs, one of the world's most productive and diverse ecosystems, are currently threatened by a variety of stressors that result in increased prevalence of both bleaching and disease. Therefore, understanding the molecular mechanisms involved in these responses is critical to mitigate future damage to the reefs. One group of genes that is potentially involved in cnidarian immunity and symbiosis is GTPases of immunity associated proteins (GIMAP).

Characterization and expression of tyrosinase-like genes in the anemone Exaiptasia pallida as a function of health and symbiotic state.

Coral disease is a major threat to reef ecosystems and therefore, understanding the cellular pathways underlying disease progression and resistance is critical to mitigating future outbreaks. This study focused on tyrosinase-like proteins in cnidarians, which contribute to melanin synthesis, an invertebrate innate immune defense. Specifically, characterization and phylogenetic analysis of cnidarian tyrosinases were performed, and their role in symbiosis and a "mystery disease" in the anemone Exaiptasia pallida was investigated using qPCR.
