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.

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

Balanced polymorphism in a floral transcription factor underlies the ancient rhythm of daily sex alternation in avocado | PNAS

In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

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)

There is some research into growing edible liverworts (Marchantia polymorpha). phys.org/news/2026-01... That would work in a Mars greenhouse context.

Q&A: Is liverwort humanity's savior? Possibilities in food and medicine

Research on using Marchantia polymorpha, commonly known as liverwort, a plant closely related to moss, for food and as an ingredient in medicine and supplements is being conducted at Kobe University.

Happy to share some of the auxin Marchantia research we've been working on for a while with @fromani.bsky.social and @jimhaseloff.bsky.social. We confirm long standing suspicions that stem cells in Marchantia exist in an auxin concentration/signalling minimum, and potentially a cytokinin maximum.

Marchantia stem cell maintenance and re-establishment are controlled by MpPIN1-mediated auxin transport and ARF signalling

Meristem organization in land plants depends on coordinated auxin distribution, transport and response, yet how these processes are integrated during vegetative growth of the gametophyte of non-seed p...
