@vinayshukla.bsky.social presented at #SLS26 a model in which O2 functions as a diffusible developmental signal rather than simply a metabolic resource or stress cue.

Excited to share my latest work in @newphyt.bsky.social. Here, we used TurboID proximity labeling with CLAVATA receptors FEA3 and BAM1D in maize meristems to better understand the signaling pathways important for meristem regulation. #PlantScience

I'd love a reporter to ask him to explain what an intercalary meristem is and why it's very important for golf courses.

Super cool snapdragon update:

I cut off the apical meristem of my tricot snapdragon and initially its first leaves from lateral meristem were paired, but now each branch throwing triplets, and three branches per node! A TRUE tricot bodyplan!

It was already known that auxins (surprise!) had a key role controlling the end of flowering, plant menopause. Now we can tell you how and where they act in the inflorescence meristem to control the process.

New insights into cell fates of the Arabidopsis inflorescence meristem

@sebamorenor.bsky.social generated the most detailed map to date of this critical stem cell niche, identifying 18 distinct cell type clusters, including precursors to cortex & vascular tissues

www.slcu.cam.ac.uk/news/new-ins...
Inflorescence meristem cell identities: (A) Force-directed graph layout of clusters associated with inner cell layers such as early primordia (EP), undifferentiated cells, procambium, xylem parenchyma and cortex. Clusters are represented by different colours. (B) Schematic illustration of selected cell identities in the primary stem and inflorescence meristem. Procambial strands arise in developing primordia and give rise to vascular bundles, which subsequently differentiate into phloem, cambium and xylem within the primary stem. The exact locations of cell identities in the primary stem are schematically represented rather than accurately portrayed. Illustration by first author first author Dr Sebastián Moreno-Ramírez.

Fasciated dandelion, Taraxacum officinale.
The inflorescence meristem flattens into a flat "strap" meristem and the florets form along a pair of lines.
It always looks a bit sinister to me, like a hungry mouth. #WildflowerHour
A flattened dandelion inflorescence. It looks a bit like someone stepped on it, but it forms this way. The stem is flattened too.
