| Acantharia (Radiolaria) are widespread and abundant heterotrophic marine protists, some of which can host endosymbiotic eukaryotic microalgae. Although this photosymbiotic association was first described at the end of the 19th century, the diversity of the symbiotic microalgae remains poorly characterized. Here, we examined the identity of the microalgae associated with the acantharian species Acanthochiasma sp. by sequencing partial 18S and internal transcribed spacer (ITS) ribosomal DNA genes from cultured symbionts and directly from isolated holobiont specimens. Single Acanthochiasma cells contained multiple symbiotic partners, including distantly related dinoflagellates (Heterocapsa sp., Pelagodinium sp., Azadinium sp. and Scrippsiella sp.) as well as... |
