Evolution: Plumbing the Depths of Diplonemid Diversity
نویسندگان
چکیده
Environmental molecular sequence surveys have opened a window on the hidden riches of the microbial biosphere. Recent genetic 'barcoding' and single-cell genomics studies have provided a snapshot of the biology of diplonemids - abundant, diverse, marine heterotrophic protists whose ecological roles are becoming clearer.

Pan-oceanic distribution of new highly diverse clades of deep-sea diplonemids.
Molecular rRNA gene surveys reveal a considerable diversity of microbial eukaryotes in different environments. Even within a single clade, the number of distinct phylotypes retrieved often goes beyond previous expectations. Here, we have used specific 18S rRNA PCR primers to investigate the diversity of diplonemids, a poorly known group of flagellates with only a few described species. We analy...
متن کاملMorphological Identification and Single-Cell Genomics of Marine Diplonemids
Recent global surveys of marine biodiversity have revealed that a group of organisms known as "marine diplonemids" constitutes one of the most abundant and diverse planktonic lineages [1]. Though discovered over a decade ago [2, 3], their potential importance was unrecognized, and our knowledge remains restricted to a single gene amplified from environmental DNA, the 18S rRNA gene (small subuni...
متن کاملExtreme Diversity of Diplonemid Eukaryotes in the Ocean
The world's oceans represent by far the largest biome, with great importance for the global ecosystem [1-4]. The vast majority of ocean biomass and biodiversity is composed of microscopic plankton. Recent results from the Tara Oceans metabarcoding study revealed that a significant part of the plankton in the upper sunlit layer of the ocean is represented by an understudied group of heterotrophi...
متن کاملSome ecological indices of the Caspian Sea Amphipoda at the different depths Guilan offshore
In the present study, some ecological factors were studied for Amphipoda at different depths. The Shannon, Margalef, and Hill indices were used to determine the species diversity, richness and evenness, respectively. In addition, the association and niche overlap values were estimated. Indices of species richness and diversity were highest at 50 and 100m depths, respectively. The ordination o...
