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 Magazine @science.org · 6d

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.

Amazing work by the Santiago lab @unil.bsky.social. The malectin-LRR receptor kinase IGP1 senses cello-oligomers to alert the plant immune system & enhance disease resistance. Very nice discovery & mechanism.

🌱✂️ How do plant cells decide where to divide?

Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations.
