Marine picocyanobacteria, Prochlorococcus and Synechococcus, substantially contribute to marine primary production and have been the subject of extensive ecological and genomic studies. Little is known about their close relatives from freshwater and

Anoxygenic phototrophic Fe(II)-oxidizers (photoferrotrophs) are thought to have thrived in Earth’s ancient ferruginous oceans and played a primary role in the precipitation of Archean and Paleoproterozoic (3.8-1.85 Ga) banded iron formations (BIF).

Autor: B D A Naafs, Patricia Sánchez-Baracaldo, Fanny M. Monteiro, Giorgio Bianchini

Publikováno v: Naafs, B D A, Bianchini, G, Monteiro, F M & Sanchez-Baracaldo, P 2022, ' The occurrence of 2-methylhopanoids in modern bacteria and the geological record ', Geobiology, vol. 20, no. 1, pp. 41-59 . https://doi.org/10.1111/gbi.12465

The 2-methylhopanes (2-MeHops) are molecular fossils of 2-methylbacteriohopanepolyols (2-MeBHPs) and among the oldest biomarkers on Earth. However, these biomarkers’ specific source is currently unexplained, including whether they reflect an expans

Reply to Nakov et al.: Model choice requires biological insight when studying the ancestral habitat of photosynthetic eukaryotes

Autor: Patricia Sánchez-Baracaldo, John A. Raven, Andrew H. Knoll, John P. Huelsenbeck, Giorgio Bianchini, Davide Pisani

After reanalyzing the dataset presented by Sanchez-Baracaldo et al. (1), and contrary to their findings, Nakov et al. (2) conclude that the most-recent common ancestor of the Archaeplastida inhabited marine habitats. Nakov et al. (2) implemented addi
