Enhancement of Arabidopsis growth by <i>Enterobacter</i> sp. SA187 under elevated CO<sub>2</sub> is dependent on ethylene signalling activation and primary metabolism reprogramming Open
As atmospheric CO 2 levels continue to increase, optimizing the CO 2 fertilization effect which often falls short of its potential due to the physiological and metabolic limitations of plants becomes crucial. This study investigates the ro…

A bivalent histone mark reader, AtDEK2 governs plant immunity Open
In Arabidopsis thaliana, the nuclear protein DEK2 orchestrates diverse chromatin-related processes and exhibits phosphorylation in response to flagellin22 treatment, implicating its involvement in plant immunity against bacterial pathogens…

Integrated multi‐omics and genetic analyses reveal molecular determinants underlying Arabidopsis <i>snap33</i> mutant phenotype Open
SUMMARY The secretory pathway is essential for plant immunity, delivering diverse antimicrobial molecules into the extracellular space. Arabidopsis thaliana soluble N‐ethylmaleimide‐sensitive‐factor attachment protein receptor SNAP33 is a …

Pathogen-induced m6A dynamics affect plant immunity Open
Posttranscriptional regulation of mRNA mediated by methylation at the N6 position of adenine (N6-methyladenosine [m6A]) has profound effects on transcriptome regulation in plants. Focused studies across eukaryotes offer glimpses into the p…

Analysis of the Arabidopsis<i>coilin</i>mutant reveals a positive role of AtCOILIN in plant immunity Open
Biogenesis of ribonucleoproteins occurs in dynamic subnuclear compartments called Cajal bodies (CBs). COILIN is a critical scaffolding component essential for CB formation, composition, and activity. We recently showed that Arabidopsis (Ar…

MPK3 and MPK6 control salicylic acid signaling by up-regulating<i>NLR</i>receptors during pattern- and effector-triggered immunity Open
Arabidopsis thaliana mitogen-activated protein kinases 3 and 6 (MPK3/6) are activated transiently during pathogen-associated molecular pattern-triggered immunity (PTI) and durably during effector-triggered immunity (ETI). The functional di…

Both transient and sustained MPK3/6 activities positively control expression of NLR genes in PTI and ETI Open
Arabidopsis thaliana Mitogen Activated Protein Kinases 3 and 6 (MPK3/6) are known to be activated transiently in PAMP-Triggered Immunity (PTI) and durably in Effector-Triggered Immunity (ETI). However the functional differences between the…

Chromatin phosphoproteomics unravels a function for AT-hook motif nuclear localized protein AHL13 in PAMP-triggered immunity Open
Significance Mitogen-activated protein kinases (MAPKs) function in all eukaryotes in signaling extracellular stimuli to intracellular responses and ultimately link them to chromatin events by targeting transcription factors and chromatin r…
View article: The Trihelix transcription factor GT2-like 1 (GTL1) promotes salicylic acid metabolism, and regulates bacterial-triggered immunity
The Trihelix transcription factor GT2-like 1 (GTL1) promotes salicylic acid metabolism, and regulates bacterial-triggered immunity Open
The Trihelix Transcription factor GT2-like 1 (GTL1) was previously shown to be a key regulator of ploidy-dependent trichome growth and drought tolerance. Here, we report that GTL1 plays an important role in coordinating plant immunity. We …

Plant Immunity: The MTI-ETI Model and Beyond Open
In plant-microbe interactions, a pathogenic microbe initially has to overcome preformed and subsequently induced plant defenses. One of the initial host-induced defense responses is microbe-associated molecular pattern (MAMP)-triggered imm…

The <i>Arabidopsis</i> homolog of human G3BP1 is a key regulator of stomatal and apoplastic immunity Open
Mammalian Ras-GTPase–activating protein SH3-domain–binding proteins (G3BPs) are a highly conserved family of RNA-binding proteins that link kinase receptor-mediated signaling to RNA metabolism. Mammalian G3BP1 is a multifunctional protein …

Nuclear Signaling of Plant MAPKs Open
Mitogen-activated protein kinases (MAPKs) are conserved protein kinases in eukaryotes that establish signaling modules where MAPK kinase kinases (MAPKKKs) activate MAPK kinases (MAPKKs) which in turn activate MAPKs. In plants, they are inv…
