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.

Very excited to see our @nikogeldner.bsky.social lab x Feng Zhou lab work featured on the cover of Science!
(1/5) We reveal how root architecture and nutrient leakage shape spatial patterns of microbial colonization, moving beyond traditional models of uniform exudation.
science.org
Using precise spatial and temporal analysis, researchers in Science provide insight into how bacteria around the root interact both with the plant and with each other.

A confocal microscopy image shows root-colonizing bacteria clustering around an emerging lateral root, where localized glutamine leakage induces spatially confined reporter activity.

This is a box crab 📦🦀, likely Calappa calappa (from a Malay word meaning "coconut").

They're also called 'shame-faced crabs' because they pull their massive claws (chelae) in front of their face when alarmed.

Why are they squirting? This is a way of moving water over their gills to keep them wet.

And what a fantastic edition of #ISPLORE2025JP it was! Really had a wonderful time discussing science, meeting old friends and making new and enjoying the local cuisine 🌱🍣
