Arabidopsis coordinates Fe acquisition with its root microbiota by releasing distinct coumarin chemotypes in response to environmental pH. These root-exuded specialized metabolites interact with root-...

In roots, the endodermis controls nutrient entry by forming a barrier known as the Casparian strip. Yet how barrier-associated processes interface with systemic signaling remains unclear. Here, we sho...

Iron acquisition is a critical challenge for plants, especially in iron-deficient soils. Recent research underscores the importance of root-exuded coumarins in modulating the root microbiome communi.....

The plant microbiome can protect its host against detrimental bacterial strains. This study shows that competition among Pseudomonas bacteria in synthetic bacterial communities determines how well the...

Bacterial genes required for plant colonization are highly host- and organ-specific. An efflux pump detoxifies specific Arabidopsis glucosinolates to protect commensal bacteria from plant chemical def...

Researchers pinpoint the genes responsible for the final three pea traits studied by the famed citizen scientist.

Abstract. Jasmonic acid (JA), ethylene (ET) and salicylic acid (SA) are the three major phytohormones coordinating plant defense responses, and all three a

Plant performance depends on the soil microbiome. While microbiome feedbacks are well documented, the mechanisms by which plants perceive and mediate these feedbacks remain unclear. We established a f...

The authors show that immunosuppression is highly conserved in the bacterial order Xanthomonadales. This feature, which preceded their specialization as host-adapted pathogens, probably contributes to...
