Root-associated Streptomyces produce galbonolides to modulate plant immunity and promote rhizosphere colonisation

This study identifies galbonolides as metabolites produced by Streptomyces AgN23 that modulate plant immunity and promote rhizosphere colonization by triggering defense mechanisms and inhibiting competitors.

Conservation of symbiotic signalling across 450 million years of plant evolution

This study shows that the common symbiotic pathway genes are essential for arbuscular mycorrhizal symbiosis in bryophytes, indicating conservation of this pathway for 450 million years.

Annexin and calcium-regulated priming of legume root cells for endosymbiotic infection

This study identifies MtAnn1 annexin as a key regulator of calcium signaling and cytoplasmic bridge formation during legume root infection by rhizobia.

TBL38 is an atypical homogalacturonan acetylesterase with a peculiar cell wall microdomain localization in Arabidopsis seed mucilage secretory cells

This study identifies TBL38 as an atypical homogalacturonan acetylesterase localized in a specific cell wall microdomain of Arabidopsis seed mucilage secretory cells, showing increased acetylation in mutants.

Medicago truncatula SOBIR1 controls specificity in the Rhizobium-legume symbiosis

This study identifies MtSOBIR1 as an interactor of MtNFP in Medicago truncatula, showing it has dual roles in immunity and symbiosis with Rhizobium.

The association between Dioscorea sansibarensis and Orrella dioscoreae as a model for hereditary leaf symbiosis

The paper demonstrates a leaf symbiosis between Dioscorea sansibarensis and Orrella dioscoreae as a model for hereditary symbiosis, showing that aposymbiotic plants can be generated and re-inoculated with genetically manipulated bacteria.

Pathogen-derived mechanical cues regulate the spatio-temporal implementation of plant defense

The paper shows that mechanical cues from fungal pathogens trigger immunity in distant plant cells through changes in cell wall tension and cortical microtubule reorganization.

A DEAD BOX RNA helicase from Medicago truncatula is hijacked by an RNA-binding effector from the root pathogen Aphanomyces euteiches to facilitate host infection

This study identifies an RNA-binding effector from a plant pathogen that disrupts ribosome biogenesis and hijacks a host RNA helicase to promote infection.
