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.

My new preprint: When R ~ B(n, p) and n/k -> b > 0, then the k:th raw moment of R is asymptotically k^k (Psi +/- epsilon)^k. Earlier only upper and lower bounds of Psi existed, and a recent sharp result when n/k -> infinity. TODO: the case n/k -> 0. arxiv.org/abs/2504.05766
On raw moments of the binomial distribution
We study the $k$:th raw moment of a variable $R$ following the binomial distribution $\text{B}(n, p)$, where $n/k \rightarrow β> 0$. It is known that $\mathbb{E}(R^k)$ is bounded both from below and f...

Yesterday we had a great talk by Tom Clement from the New Dawn Bio startup on the potential of growing wood in cell cultures. Hosted by Wiktoria Fatz from our CoE.

TBR is an RG-I rhamnose O-acetyltransferase required for epidermal cell adhesion in Arabidopsis thaliana
Pectins are enriched in primary cell walls and the middle lamella, determining cell-to-cell adhesion. O-acetylation of pectin backbones influences their physicochemical properties and plays a role in ...

Finally out! We identified the stem cell factors (CAILs) of the vascular cambium, and a mechanism involving a ligand sequestration to position the stem cells. This work is a result of fruitful collaboration with @peteretchells.bsky.social and Tusscher labs. 🧵 1/x
