Congratulation @transitionalform.bsky.social @instmolplantsci.bsky.social for publishing the next chapter of your thesis @currentbiology.bsky.social ! Great work showing that the two fundamental vascular tissues - xylem and phloem evolved asynchronously. Read Laura's thread for more details 👇👇

Laura Cooper@transitionalform.bsky.social · last mo.

Our paper on the origin and evolution of phloem, a big part of my PhD work, is out in Current Biology! www.sciencedirect.com/science/arti...

With James Clark, he also found WOX13LC to be ancient, arising from a duplication of WOX13LA/B genes and sequence divergence in peristomate mosses. In the paper available on the link below, we present some models of PpWOX13L function and evolution. www.sciencedirect.com/science/arti...

Soils drive convergence in the regulation of vascular tension in land plants

Terrestrial vascular plants operate under negative water potential, which results in hydraulic tension in the vascular system. Vascular tension varies with transpiration and soil drying and is regulat...

Happy to see this out! We describe a patterning mechanism underlying rhizoid specification in Marchantia. Contrary to classic patterning mechanisms (e.g., Turing), rhizoid specification depends on both randomness and lateral inhibition, involves subcritical bifurcations, and occurs at criticality!

Cell-type specification at criticality underlies rhizoid patterning in the liverwort Marchantia polymorpha

Rhizoid specification in Marchantia polymorpha gemmae involves lateral inhibition mediated by the microRNA FRH1, which represses the rhizoid-specific …
