This study shows that Aurantiochytrium, a heterotrophic protist, thrives on viral-induced dissolved organic matter from virus-infected Heterosigma akashiwo, highlighting its role in carbon cycling after algal blooms collapse.

The paper investigates the relationship between mitochondrial and non-coding nuclear DNA content in kinetoplastids, finding an inverse correlation that suggests co-evolution of genome sizes.

This paper shows that facultative anaerobes use CO-dependent proton respiration to survive electron acceptor limitation, mediated by Ni-CODH/ECH, which is redox-regulated and provides a reliable energy source in variable environments.

The paper presents transcriptomic data for 11 free-living neobodonid kinetoplastids and reveals they are paraphyletic, with other metakinetoplastids descending from them.

This study shows that viral infection of the alga Heterosigma akashiwo alters its organic matter composition, promoting growth of specific Vibrio species that may impact marine food webs.

The paper identifies genes under positive selection in symbiotic and free-living Symbiodinium species and shows phenotypic differences in starch accumulation.

The paper reports mitochondrial genomes from three Ancyromonadida protists, revealing novel gene features and expanding the known mitochondrial gene repertoire of ancestral eukaryotes.

This study estimates the root of the eukaryote Tree of Life using mitochondrial proteins, finding it between Opimoda+ and Diphoda+ supergroups.

This study examines how acetate affects CO2 fixation pathways in thermophilic bacteria, showing acetate suppresses the WL pathway and promotes the rTCA cycle in some species.

This study reports the diploid genome of the free-living diatom Nitzschia putrida and identifies genetic changes associated with its transition from a photosynthetic to a non-parasitic secondary heterotrophic lifestyle.
