This is a coral larva-notice its highly motile cilia. It must constantly sense its environment to decide where to start a colony. Much of reef resilience being here, yet this biology remains largely unexplored. Work from ADC-NiCE @scrippsocean.bsky.social supported by @allenphilanthro.bsky.social

How does marine life sense and respond to their changing world? The Allen Discovery Center for Neurobiology in Changing Environments is diving (literally) into this #FrontierScience. 🐋🧠

Co-option of immune and digestive cellular machinery to support photosymbiosis in amoebocytes of the upside-down jellyfish Cassiopea xamachana Summary: Jellyfish amoebocytes promote photosynthesis by their endosymbiotic algae using proton pumps and carbonic anhydrases. These two enzymes ubiquitously acidify phagosomes, lysosomes and inverteb...

Amebocytes of the upside-down #Cassiopea #jellyfish acidify the symbiosome using the #V-ATPAse, which promotes photosynthesis. Similarities with corals, anemones, giant clams and diatoms suggest convergence evolution and link phagocytosis symbiosis and symbiogenesis.

Evolutionary insights into gut acidification: invertebrate-like mechanisms in the basal vertebrate hagfish Summary: Digestive acidification in hagfish is mediated by VHA and the cAMP pathway and VHA performs both invertebrate- and gnathostome-like digestive functions.

#Hagfish acidifies its gut using #V-ATPAse. This is more similar to invertebrates than vertebrates with implications for food digestion, immunology and #symbiosis. Led by Alyssa Weinrauch w/ Greg Goss @garfieldkwan.bsky.social

An acidic microenvironment produced by the V-type ATPase of Euprymna scolopes promotes specificity during Vibrio fischeri recruitment - Communications Biology Production of an acidic microenvironment by the juvenile host’s epithelial V-type ATPase promotes the recruitment of its specific bacterial symbiont from the ambient environment.

Bobtail squid uses the #V-ATPase proton pump to acidify the microenvironment in its light organ, which promotes specificity for the recruitment of bacterial symbionts. Does this strategy apply to other #symbioses?
