A Proxitome-RNA-capture Approach Reveals that Processing Bodies Repress Co-Regulated Hubs

The paper introduces a Proxitome-RNA-capture method to study RNA composition in Arabidopsis processing bodies, revealing dynamic RNA regulation and its role in stress responses.

The functional and structural characterization of Xanthomonas campestris pv. campestris core effector XopP revealed a new kinase activity

This paper characterizes XccXopP as a novel kinase that phosphorylates AtExo70B1 and prevents its phosphorylation by AtCPK5, thereby evading host immune responses.

Atmospheric nitrogen fixation by eukaryotes: Should we reconsider the nitrogen cycle in nature?

The paper demonstrates that three yeast species can directly assimilate atmospheric nitrogen without known N2-fixation enzymes, challenging current understanding of nitrogen fixation in eukaryotes.

The core effector RipE1 of Ralstonia solanacearum interacts with and cleaves Exo70B1 and is recognized by the Ptr1 immune receptor

This paper identifies RipE1, a Ralstonia solanacearum effector, as a cysteine protease that targets Exo70B1 in the host secretion machinery and is recognized by the Ptr1 immune receptor.

Assassination Tango: An NLR/NLR-ID immune receptors pair of rapeseed co-operates inside the nucleus to activate cell death

The paper identifies a novel NLR/NLR-ID pair in rapeseed that cooperates in the nucleus to activate cell death, differing from previously reported negative regulation mechanisms.

Expression of putative effectors of different Xylella fastidiosa subspecies/strains reveals recognition and defense activation in various model plants

This study identifies Xylella fastidiosa putative effectors that differentially elicit cell death-like phenotypes in model plants, revealing their potential roles in pathogenicity.

The host exocyst complex is targeted by a conserved bacterial type III effector protein that promotes virulence

This study identifies XopP, a bacterial effector that targets the host exocyst complex to inhibit plant immunity and promote infection.

Halophytic bacterial endophytome: a potential source of beneficial microbes for a sustainable agriculture

This study isolates and identifies endophytic bacteria from halophytes, showing their potential as bio-inoculants to improve plant growth and stress tolerance in sustainable agriculture.
