Ever had issues with contamination in #Marchantia or #liverwort tissue culture? We've developed a protocol that is simple and low-effort (albeit slow) to get rid of fungi and bacteria: dx.doi.org/10.17504/pro.... Work led by Isaac Coven and supported by Chetan Pandey, myself & @dromius.bsky.social.

How do transcription factors bind DNA strongly, and in a switch like manner, while remaining sequence specific? Our new paper on a canonical plant TF suggests the answer is a previously underappreciated assembly state: transcription factor nanoclusters. www.science.org/doi/10.1126/...
Nanoclustering of a plant transcription factor enables strong yet specific DNA binding
Transcription factor nanoclusters balance the DNA binding trade-off between weakly binding oligomers and nonspecific condensates.

Weniger Erdgas und CO2: Wissenschaftler forschen an Bakterien-Pflanzen-Symbiosen
Kunstdünger braucht viel Erdgas und schadet Klima und Gewässern. Forschende in Freiburg wollen, dass Nutzpflanzen sich mithilfe von Bakterien selbst mit Stickstoff versorgen.

Preprint! How do "friendly" rhizobia build a legume nodule? @albinteulet.bsky.social found that some may carry hidden transcription factors - proteins that mimic DNA-binding folds to enter the plant nucleus and rewrite its developmental program. www.biorxiv.org/content/10.6... (1/6)
