Congratulations to the new Doctor in the lab, Álvaro Jiménez-Jiménez. Fantastic defense work!! 🧑‍🎓🥳

Check out our new review metacaspases in Cell Death & Differentiation @springernature.com . It´s not all about cell death, but more about survival 👇https://www.nature.com/articles/s41418-025-01555-y

Fantastic plenary talk by Nuria Coll @bactodeath.bsky.social on how to use metabolic engineering to make plants resistant to vascular pathogens #2025ISMPMI

Great to catch up on plant cell death ...

The CAPE1 peptide confers resistance against bacterial wilt in tomato Resistance against bacterial wilt in tomato is linked to variety-specific proteomic changes; the CAPE1 peptide restricts Ralstonia solancearum growth in pl

Cell-type specific autophagy in root hair forming cells is essential for salt stress tolerance in Arabidopsis thaliana Autophagy is a vital cellular quality control pathway that enables plants to adapt to changing environments. By degrading damaged or unwanted components, autophagy maintains cellular homeostasis. Whil...

Jierui Zhao (Dagdas Lab @plantophagy.bsky.social ) shows that cell-fate dependent upregulation of autophagic flux in Arabidopsis root hair cells promotes plant salt stress resilience by sodium ion sequestration to the vacuole www.biorxiv.org/content/10.1...

Very excited to share the final version of our story on Arabidopsis autoimmunity @emboreports.org

Big day for the lab today! Nerea Ruiz-Solaní obtained her PhD with an amazing defense and an amazing jury! Congratulations Nerea 👏

Root hair lifespan is antagonistically controlled by autophagy and programmed cell death Root hairs are tubular tip-growing extensions of root epidermal cells that enhance root surface area for water and nutrient uptake. While mechanisms governing root hair fate, polarity, and tip growth ...

Qiangnan Feng (Nowack lab @moritznowack.bsky.social @psb-vib.bsky.social ) shows that cell-type specific elevated autophagy in root hairs extends their lifespan by suppressing premature senescence and age-induced programmed cell death www.biorxiv.org/content/10.1...

A bacteria-based Band-Aid helps plants heal their wounds Recent research into bacterial cellulose patches may speed plants' recovery, improve grafting and help with preservation.

Biological band-aids for plants? 🩹🌿

A study just published at #ScienceAdvances from Núria Sánchez-Coll’s lab at CRAG @bactodeath.bsky.social reveals that bacterial cellulose promotes plant tissue regeneration via two key mechanisms 👀

The research was co-led by Miguel Ángel Moreno Risueño from CBGP @cbgpmadrid.bsky.social & in collaboration with @icmabcsic.bsky.social and the #ColoradoStateUniversity

Exogenous bacterial cellulose induces plant tissue regeneration through the regulation of cytokinin and defense networks Bacterial cellulose application concurrently targets cytokinin- and ROS-associated defense responses to induce plant regeneration.

Have a look at our new story on how Bacterial Cellulose works miracles in plant wound healing by activating regeneration via concurrent activation of ROS, defense and cytokinin signalling. In collaboration with @cbgpmadrid.bsky.social @icmabcsic.bsky.social

New paper alert! The Dagdas group @plantophagy.bsky.social discovered that the molecule ATG8 protects the vacuole when the cell wall is damaged. This mechanism ensures that the highly pressured vacuole, essential to the plant cell, remains intact. Read more: bit.ly/4aLCZK9
