The paper uses molecular clock dating with non-symbiotic Bradyrhizobium relatives to show nodulation and legumes emerged around 90-80 million years ago.

This paper describes the isolation and characterization of Ruegeria persistens sp. nov., a coral-associated bacterium that persists in a coral holobiont over eight months.

This paper identifies free-living Bradyrhizobium as the ancestral state of nitrogen fixation, showing that symbiotic nitrogen fixation evolved multiple times independently from free-living ancestors.

The paper identifies a coral probiotic strain with enhanced thermal tolerance and characterizes its genomic and functional traits associated with long-term host association.

This paper identifies a probiotic bacterium with persistent colonization in corals using evolutionary genomic markers, showing improved thermal tolerance and survival during bleaching.

This study shows that Proterozoic tectonic events, not glycan specialization, drove Flavobacterial diversification by enabling marine-to-non-marine habitat transitions.

The paper isolates two new CHAB-I-5 strains, analyzes their genomes, and proposes a new genus and species, highlighting ecological and physiological differences.

The paper expands the diversity of nod-free Bradyrhizobium strains and shows that NF-independent nodulation is common in this supergroup.

This study shows that the reverse dissimilatory sulfite reductase (rDsr) pathway can independently oxidize thiosulfate under low oxygen conditions, supporting its ecological role in marine sediments.

This study estimates the origin of ammonia-oxidizing bacteria (AOB) using eukaryotic fossils and Bayesian dating, finding they emerged between 2.1 and 1.9 billion years ago.

The paper investigates genome reduction in marine bacterioplankton, finding that neutral processes like genetic drift, not streamlining selection, drive genome size reduction in the Roseobacter group.

The paper uses agent-based modeling to show that drift, not selection, drove genome reduction in early Prochlorococcus by analyzing the dR/dC substitution ratio.
