Journal Article Molecular biology and evolution · October 2025 Species are a fundamental unit of biodiversity. Yet, the existence of clear species boundaries among bacteria has long been a subject of debate. Here, we studied species boundaries in the context of the phylogenetic history of Nostoc, a widespread genus of ... Full text Cite

Central metabolism and development are rewired in lichenized cyanobacteria.

Journal Article The ISME journal · January 2025 Nostoc cyanobacteria are among the few organisms capable of fixing both carbon and nitrogen. These metabolic features are essential for the cyanolichen symbiosis, where Nostoc supplies both carbon (as glucose) and nitrogen (as ammonium) to a cyanolichen-fo ... Full text Cite

Phylometagenomics of cycad coralloid roots reveals shared symbiotic signals

Journal Article Microbial Genomics · March 7, 2024 Cycads are known to host symbiotic cyanobacteria, including Nostocales species, as well as other sympatric bacterial taxa within their specialized coralloid roots. Yet, it is unknown if these bacteria share a phylogenetic ... Full text Cite
