The Cell Wall as a Biophysical Gatekeeper of Iron Homeostasis in Plant Roots

Yesterday, Chenlu Liu (from the @elkebarbez.bsky.social group) revealed how dynamic cell wall charge regulates iron uptake in plant roots, acting as a reversible ion filter that shapes nutrient balance.

Acylamino acid-releasing enzyme, a bifunctional protease with a potential role in aging We consolidate information on Acylamino acid-releasing enzyme, a serine protease affecting plant development and aging, and emphasize its conserved feature

Our review "Acylamino acid-releasing enzyme, a bifunctional protease with a potential role in aging" is now out in JXB with full citation. Please check it out.
AARE is deeply conserved in evolution. So it's far more than #plantscience.

Vol 76 Issue 15 2025 Journal of Experimental Botany Plant Proteases: Guardians of Proteome Integrity and Function Cover illustration: Proteases play key roles in guarding proteome integrity and regulating protein function. The reviews and research articles in this special issue put a timely spotlight on the fascinating diversity, function and regulation of proteases in plants. Selected topics rise as bubbles above University of Hohenheim, where they were first presented at the 6th International Conference on Plant Proteases (photo courtesy of Universität Hohenheim/Maximilian Pircher; logo by Renier van der Hoorn). See Jeran et al., pp. 4294–4312; Peiyi Wang et al., pp. 4359–4373; Mantz et al., pp. 4279–4293; Calvanese et al., pp. 4326–4339; Fei Wang et al., pp. 4220–4231.

‘It was an honor to meet Minister Olschowski and share how the vision of CIBSS to decode decision-making in living systems holds great promise for sustainable agriculture and human health.’ - Prof. Jürgen Kleine-Vehn, who together with Prof. Sonja Albers presented our Cluster’s research. 1/5

Love goes out to all the fly peeps @edrc2025.bsky.social, fantastic meeting and we had brilliant time together with @classenlab.bsky.social in Alicante!♥️♥️♥️
Can’t wait for the EDRC 2027 in Bonn!

Proteins can form condensates to boost interactions and gene control. This week @gjjang.bsky.social (from @mpi-ie.bsky.social) shows how plants use them in transcription and epigenetics, and how super-resolution microscopy reveals them in vivo.

ERAD machinery controls the conditional turnover of PIN-LIKES in plants Plant ERAD machinery governs the turnover of auxin transporters involved in developmental and stress responses.

1/ 🌱 When plants face stress, they often suppress growth to save resources.
In our new Science Advances paper, we reveal how: plants repurpose their ER quality control machinery (ERAD) to regulate auxin compartmentalization and thus growth.
