Abstract. Paleobiologists have long sought to explain how alternative modes of speciation, including budding and bifurcating cladogenesis, shape patterns o

While DNA has built the framework for molecular insights from museum collections, the utility of archival RNA remains largely unexplored. Likely a consequence of the known instability of RNA relative ...

Grenz et al. interrogate the Pseudomonas syringae species complex for its capacity to infect evolutionarily divergent host plants. Their results demonstrate that broad host isolates from phylogroup 2 rely on the lipopeptide toxin syringomycin to promote host necrosis and enhance bacterial growth in plants.
