Congrats Madeleine!

Symbiotic diversification relies on an ancestral gene network in plants Symbioses have been fundamental to colonization of terrestrial ecosystems by plants and their evolution. Emergence of the ancient arbuscular mycorrhizal symbiosis was followed by the diversification o...

Beware giving this site your unpublished data Users noticed the website had fake testimonials and a domain name registered seemingly overnight.

PSA: Many of you may have noticed a website floating around called formatmypaper(dot)com. People rightly noted something was fishy. I dig into what happened here:

EPP1 is an ancestral component of the plant Common Symbiosis Pathway The success of plants on land has been enabled by mutualistic intracellular associations with microbes for 450 million years ([Delaux and Schornack 2021][1]). Because of their intracellular nature, th...

So happy to see the latest preprint of the team out! www.biorxiv.org/content/10.1...

Fig. 2.Confocal microscopy of N. punctiforme strains. Filaments from the indicated strains were taken from cultures grown in BG110 medium (not induced; A) or after incubation for 24 h in the presence of Anthoceros agrestis exudates (hormogonia induction; B) and visualized by confocal microscopy. Merged (2 channels) show the overlay of autofluorescence (magenta) and GFP fluorescence (green). Merged (3 channels) represent the overlay of magenta autofluorescence, bright field, and green GFP fluorescence. Hormogonia are identified as short filaments with small cells. Scale bar=20 μm.

💡🔬 TECHNICAL INNOVATION 💡🔬

Neubauer et al. developed a Nostoc reporter strain enabling high-throughput quantitative monitoring of hormogonia differentiation in cyanobacteria as a response to biotic and abiotic factors.
