A molecular ‘gatekeeper’ in plants opens the door for beneficial microbes CIBSS researchers at the University of Freiburg are part of an international team that sheds light on a crucial step in the initiation of the symbiosis between plants and soil bacteria.

This should be super helpful for anybody working on #PlantCellWalls, particularly #Cellulose.

A step-by-step guide for quantitative(!) live-imaging of cellulose synthesis in planta.

Join @berasymbionts.bsky.social , @tatsuyanobori.bsky.social and us for a postdoc on the remarkable developmental biology of symbiosis!

Applications are due March 25th 🪲🦠

Yes, it has that built-in, and we did that in a second track, but in this case we wanted to image Suberization.

Thank you @dvonwangenheim.bsky.social @the.3i.social for this awesome demo of your spinning disc system for #rootimaging

Very nice! Congrats Katharina, Pierre-Marc and the whole team! :-)

Motif-based substrate mapping of the receptor-like cytoplasmic kinase BIK1 reveals novel components and regulatory nodes of plant immunity - Nature Plants Cell surface receptors perceive immunogenic elicitors, triggering downstream signalling via receptor-like cytoplasmic kinases such as BIK1. Here the authors define and use the phosphorylation motif of...

Very impressive work identifying novel BIK1 substrates (and immunity players) in Arabidopsis 🔽!

@deutschebahn.com it would be cool with a sticker book like in the good old days to collect all your delay reasons. - like a bingo. First full book gets to delay 3 trains of their own choice!

Actually fits what we see in the transcriptome of pad3 and b2/b3

An Arabidopsis leaf-infection assay with Alternaria alternata showing lesions on Col-0, defenseless (abi1-1 coi1 eds1 ein2 rbohD sid2) and cyp79b2b3 plants. The lesions are worst on cyb79b2b3, intermediate on the defenseless plant, and least on Col. Similarly, plants infected with Pseudomonas syringae show strongest susceptibility in an eds1 sid2 background, medium susceptibility in defenseless, and least in Col.

Interesting that a 𝘥𝘦𝘧𝘦𝘯𝘴𝘦𝘭𝘦𝘴𝘴 mutant (𝘢𝘣𝘪𝟣-𝟣 𝘤𝘰𝘪𝟣 𝘦𝘥𝘴𝟣 𝘦𝘪𝘯𝟤 𝘳𝘣𝘰𝘩𝘋 𝘴𝘪𝘥𝟤) is less sensitive to fungal infection than a 𝘤𝘺𝘣𝟩𝟫𝘣𝟤/𝘣𝟤 mutant (Similarly, 𝘦𝘥𝘴𝟣 𝘴𝘪𝘥𝟤 is more susceptible to bacterial infection than the 𝘥𝘦𝘧𝘦𝘯𝘴𝘦𝘭𝘦𝘴𝘴).

During the spring of 2026, we will open a position as Assistant/Associate Professor in Plant Biochemistry.
If you think plant terpenoid biochemistry is your thing (or you know a good candidate for this), and you want to move to the middle of France, then follow @lbvpam.bsky.social for updates.

I don’t disagree, but this is a case-by-case thing. I have seen severely flawed papers, where I as a reviewer requested additional experiments, published in a different journal a few months later.

May their words reach politicians‘ ears…

Fig. 2 (shortened, full legend in paper): Perturbations of SlMYB41, SlMYB92, and SlWRKY71 expression affect the suberization of tomato exodermis. (A) Percentage of cross-sections showing a non-suberized, an early suberized (suberin in <50% of exodermal cells), or a late suberized (suberin in >50% of exodermal cells) exodermis phenotype in hairy root cultures of the control (empty vector), CRISPR knockout lines [Slmyb41-ko, Slmyb92-ko, Slwrky71-ko(4), and Slwrky71-ko(5)], and overexpressing lines (SlMYB41-OX, SlMYB92-OX, and SlWRKY71-OX). The number above the bars represents the number (n) of individual roots examined in each genotype. Asterisks denotes statistically significant differences between each line in comparison with the empty vector control, whereas n.s. indicates no significant differences (P<0.05, χ2 test).
