Huge congratulations @jeremywyman.bsky.social @instmolplantsci.bsky.social for publishing the results of your masters thesis @annbot.bsky.social
The work includes a new reconstruction of the Carboniferous isoetalean Oxroadia by the brilliant @palaeojules.bsky.social

🔬🌱 RESEARCH 🌱🔬

SA-induced stomatal closure via ROS→NO→K+ is unique to seed plants and is absent in ferns/lycophytes with only ROS production - Zhang et al.

Fig. 7.Changes in the guard cell vacuoles of the seed plants V. faba and G. biloba and the fern M. struthiopteris in response to SA. (A) The guard cell vacuoles of the seed plants were fragmented after SA treatment (scale bar = 10 µm). (B and C) The vacuole diameter decreased, and the average vacuole number increased in the guard cells of the seed plants V. faba and G. biloba but did not change in the fern M. struthiopteris. Twenty stomata (three plants per treatment) were measured in each independent replicate experiment. The data are presented as the means ± SE (total number of pores per treatment = 60, n = 3). Significant differences between the treatment and control groups within each species are indicated by ‘*’ (t-test, P < 0.05).

not really a fan of the final image but here's a progress screenshot of a 2023 rhynie chert drawing. I promise user 'trigonotarbida' does sometimes draw trigonotarbids.

The #lycophytes, when broadly circumscribed, are a group of vascular plants that include the clubmosses. They are sometimes placed in a division Lycopodiophyta or Lycophyta or in a subdivision Lycopodiophytina. They are one of the oldest lineages of extant (living) vascular plants; the

Lycopodium clavatum, common names include Stag's-horn clubmoss, running clubmoss, or ground pine.

These lycophytes take 8 years to germinate and another 25 years to mature. That is why plucking these over temporary holiday decorations is abhorrent. #lycopod #clubmoss #plantsky

More of my beloved Selaginella wallacei, I love finding it no matter where I am. Lycophytes represent a fascinating part of the evolutionary history of plants.

I rarely post plant pics – but lycophytes get special treatment. Looks like Lycopodium clavatum.

A great example of how comparative genomics across the full range of vascular plant lineages can be used as a catalyst for gene discovery!

Lycophytes used to be massive trees. Now you step on them hiking and don’t even notice.

Lycophytes (club mosses, spike mosses, quillworts) were once the tallest plants on Earth. They don’t have seeds but do have roots and water tubes. Now they mostly grow close to the ground.#AncientPlants

Did tiktok increase the character limit on comments recently to something mysteriously long…? Because it’s suddenly allowing the swamp to nerd. No one seems to be talking about it. Is it a glitch?

If you have any questions about lycophytes for the swamp on tiktok, now is the time.
