1/13 Thankfully, both you and your plants have a lot of sophisticated ways to fight off invading pathogens.
In our new preprint, we describe a new way in which animals and plants share a common strategy to ward off harmful bacteria.

But real connoisseurs of #AntimicrobialCompounds will want to get the vinyl boxset: #PlantScience #PlantImmunity

A vinyl box with six colored vinyl LPs sticking out of its right side. The Title "Guns in Rosettes" is on top, with the subtitle "The Arabidopsis chemical weapons arsenal" just below. Then there is an Arabidopsis plant with machine guns sticking out. Below is the statement "6-LP LIMITED EDITION COLORED VINYL BOX SET"

The back cover of the vinyl box set showing the tracklist:
1. Methionine-derived compounds
Aliphatic GSLs
2. Tryptophan-derived compounds (trptonites)
Indolic GSLs
Camalexin
Hycanite (4-OH-ICN)
3. Phenylalanine-derived compounds (phenylpropanoids)
Benzenic GSLs
Coumarins
Hydroxycinnamates
Flavonoids
4. Terpenoids
(E)-β-caryophyllene
α- and β-pinene
Thalianin, arabidin, and DMNT

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.

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.
