New #ISEPpapers! Phylogenomic diversity of archigregarine apicomplexans https://royalsocietypublishing.org/doi/full/10.1098/rsob.240141
"#Gregarines are a large and diverse subgroup of #Apicomplexa, a lineage of obligate animal #symbionts including pathogens such as #Plasmodium, the #malaria parasite. Unlike Plasmodium, however, gregarines are poorly studied, despite the fact that as early-branching #apicomplexans they are crucial to our understanding of the origin and evolution of all apicomplexans and their parasitic lifestyle."
Picomplexan parasites require specialized structures like the inner membrane complex to invade host cells and replicate. This study shows that the alveolin protein IMC6 is crucial for maintaining cellular morphology, invasion and successful replication in Toxoplasma gondii.
Coral-infecting #parasites in cold marine ecosystems https://www.cell.com/current-biology/abstract/S0960-9822(24)00323-3 #protists #microbes by Morelia Trznadel et al.
"#CoralReefs are a #biodiversity hotspot, and the association between coral and intracellular #dinoflagellates is a model for #endosymbiosis. Recently, #corals and related #anthozoans have also been found to harbor another kind of endosymbiont, #apicomplexans called #corallicolids."
