Highlights•Over 1000 mostly nuclear proteins are targets of SUMOylation in
Arabidopsis.•Stress-induced SUMO addition is important for abiotic and biotic stress …

The SUMO system is a rapid dynamic post-translational mechanism employed by eukaryotic
cells to respond to stress. Plant cells experience hyperSUMOylation of substrates in …

Plant defense is achieved mainly through the induction of microbe-associated molecular
patterns (MAMP)-triggered immunity (MTI), effector-triggered immunity (ETI), systemic …

Plant immune responses are tightly regulated to ensure their appropriate deployment.
Overexpression of TOPLESS-RELATED 1 (TPR1), a SUPPRESSOR OF npr1-1 …

The versatility of mitogen-activated protein kinases (MAPKs) in translating exogenous and
endogenous stimuli into appropriate cellular responses depends on its substrate specificity …

Brassinosteroids (BRs) play crucial roles in plant development, but little is known of
mechanisms that integrate environmental cues into BR signaling. Conjugation to the small …

SUMO modification is part of the spectrum of Ubiquitin-like (UBL) systems that give rise to
proteoform complexity through post-translational modifications (PTMs). Proteoforms are …

Abstract Background Host RNA-dependent RNA polymerases (RDRs) 1 and 6 contribute to
antiviral RNA silencing in plants. RDR6 is constitutively expressed and was previously …

Plants have evolved to cope with changing environmental conditions. One way plants
achieve this is through post-translational modification of target proteins by ubiquitination and …

Plants respond rapidly to sudden environmental cues, often responding prior to changes in
the hormone levels that coordinate these responses. How this is achieved is not fully …
