And a curious finding - in both liverworts and flowering plants independently, repurposing of this regulatory complex for lineage-specific traits is associated with duplication of the same component (the MYB transcription factor).
Although the red pigments made by flowering plants and liverworts are produced by distinct chemical pathways, here we found that they are induced by homologous complexes of transcription factors. @currentbiology.bsky.social
Kongsted et al. find that, while the red pigments produced in liverworts and seed
plants are distinct, they are regulated by homologous MYB-bHLH transcriptional complexes.
They also find that in liver...

I had the utter pleasure of working with the excellent @fromani.bsky.social, Chiara Airoldi, @jimhaseloff.bsky.social and @beverleycubg.bsky.social on this project during my PhD. Vielen Dank!

Great summaries of our paper www.science.org/doi/10.1126/... in Science: www.science.org/doi/epdf/10.... and New Scientist: www.newscientist.com/article/2515... and in the Science museum blog: blog.sciencemuseum.org.uk/in-the-begin...
Come and hear me yap about the #LiverwortHunt, a citizen science project which we (@slcuplants.bsky.social) ran in 2021, and was published last year as a part of the Marchantia polymorpha pangenome paper doi.org/10.1038/s415...
Our work on #hornwort #pyrenoids is finally out in @science.org! š We uncovered how hornworts pack their Rubisco into pyrenoids and successfully recreated them in Arabidopsis. A key step toward engineering more efficient photosynthesis in crops @btiscience.bsky.social www.science.org/doi/10.1126/...
The emergence of a chemical system capable of self-replication and evolution is a critical event in the origin of life. RNA polymerase ribozymes can replicate RNA, but their large size and structural ...
In many algae, photosynthesis is boosted by biophysical CO2-concentrating mechanisms, which pack the CO2-fixing enzyme Rubisco into liquid-like organelles called pyrenoids. Engineering C3 crops with a...
