Trees are amazing! They build their bodies from thin air, move water with pressures that would crush a human, and grow using a system of living cables wrapped in layers of corpses. Watch our video to find out how they work, and why they might even be immortal: https://kgs.link/TreesAreDead

Auxin transport positions stem cells in the vascular cambium during normal development and regeneration | PNAS
The vascular cambium contains bifacial stem cells producing secondary phloem in one
and secondary xylem to the opposite direction. In Arabidopsis r...

How plants sense injury in their barrier tissue, periderm? Painstakingly detailed and amazing work by post doc Hiroyuki Iida shows that wounding is sensed by the diffusion of two gases: ethylene and oxygen. @treebiocoe.bsky.social @erc.europa.eu 1/x 🧵 www.nature.com/articles/s41...
Plants monitor the integrity of their barrier by sensing gas diffusion - Nature
A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and pathogen entry.

SPL13 controls a root apical meristem phase change by triggering oriented cell divisions
Oriented cell divisions are crucial for determining the overall morphology and size of plants, but what controls the onset and duration of this process remains largely unknown. Here, we identified a s...
