So proud of CailinSmith, who volunteered 2 years ago to work hard to make the 2025 #GRS Plant Lipids a success!

She represents the powerful progress that young scientists everywhere bring to their fields and labs, and I'm grateful she's in mine. 😊

The #SubtiWiki paper of the month for January 2025 has been selected. It is a paper from Angelika Gründling on the discovery of the last unicorn in Gram-positive phospholipid biosynthesis!

Hallo Bluesky-Community! Ab heute berichten wir hier über die Uni Göttingen und freuen uns auf den Austausch. Wer ist auch noch hier?

Hello to everyone on Bluesky! You’ll find the University of Göttingen’s news here. We’re looking forward to the exchange! Who else is here?

Our analyses suggest dysregulated mRNA decay & accumulation of transcripts encoding master regulators of xylogenesis. Tissue-specific developmental reprogramming & de novo xylem formation ultimately increase the plant's water storage capacity & resistance to drought stress. (5/5)

We show that TRADE triggers sustained phosphorylation of VARICOSE via co-option of ABA-independent SNF1-Related Protein Kinases 2, which are known to control rapid and transient intracellular signaling for adaptation to osmotic stress and root development. (4/5)

A single pathogen-secreted protein reprograms plants for drought resilience Climate change-enforced drought stress conditions and diseases caused by pathogens often co-occur and represent one of the greatest challenges in plant science. Wilt pathogens that colonize water-cond...

Here is a preprint with potential interest to those fascinated by host-microbe interactions, abiotic stress adaptation, xylogenesis, P bodies & mRNA turnover, and extended phenotypes induced by microbial effectors: biorxiv.org/cgi/content/... (1/5)

Our findings underpin that sphingolipid production contributes to the role of the trans-Golgi network as a multi-domain sorting compartment and is required for defense against pathogen invasion.

Here, we provide evidence that INOSITOL PHOSPHORYLCERAMIDE SYNTHASE 2 (IPCS2) is involved in proper delivery of the ATP-binding cassette transporter PEN3 to polarized plasma membrane domains at plant-microbe interaction sites.

Identification of INOSITOL PHOSPHORYLCERAMIDE SYNTHASE 2 (IPCS2) as a new rate-limiting component in Arabidopsis pathogen entry control INOSITOL PHOSPHORYLCERAMIDE SYNTHASE 2 (IPCS2) is involved in the biosynthesis of complex sphingolipids at the trans-Golgi network (TGN). Here, we demonstrate a role of IPCS2 in penetration resistance...

To all colleagues who share an interest in sphingolipids, endomembrane trafficking & membrane domain formation, pathogen-induced cell polarization and entry control, here is another potentially interesting preprint: biorxiv.org/cgi/content/...
