Plasmodium falciparum apicoplast SufS is required for both iron-sulfur synthesis and tRNA modification by MnmA, a novel paradigm that is likely to apply to other plastid-containing organisms.
A combination of phylogenetic and biochemical analyses suggest that some unexpected variations in the synthesis of isoprenoids may be widespread across all three domains of life.
Mammalian cells were engineered to synthesize valine, a metabolic capacity that had been lost from the lineage of higher eukaryotes for >500 million years.

Domestication of endosymbiotic Mollicutes may have resolved nitrogen-recycling challenges for attine ants and enabled the evolutionary derived leaf-cutting ants to fully exploit their herbivorous niches.
An in-depth metagenomic analysis of possibly the most abundant and widespread microbial lineage in the surface ocean teases apart evolutionary processes that maintain its genomic heterogeneity and biogeography.
A comparison between artificially created allopolyploids and natural ones reveals that the latter underwent significant evolutionary steps after their formation.
A number of microbial eukaryotes have adapted to low oxygen conditions by acquiring a gene that allows their mitochondrial electron transport chain to continue to function when oxygen is scarce.
