SUMO Conjugation to BZR1 Enables Brassinosteroid Signaling to Integrate Environmental Cues to Shape Plant Growth.
Title: SUMO Conjugation to BZR1 Enables Brassinosteroid Signaling to Integrate Environmental Cues to Shape Plant Growth.
The study provides an insight into the molecular mechanism for understanding how the CHD3-like chromatin remodeling protein MOM1 cooperates with the SUMO E3 ligase-like proteins to regulate transcriptional silencing. [SUMO1]
Title: Exploring potential roles for the interaction of MOM1 with SUMO and the SUMO E3 ligase-like protein PIAL2 in transcriptional silencing.
Bacterial flagellin induces the conjugation of the SMALL UBIQUITIN-LIKE MODIFIER (SUMO) protein to FLS2 to trigger release of BIK1 resulting in resistant to bacterial pathogens in Arabidopsis.
Title: SUMO conjugation to the pattern recognition receptor FLS2 triggers intracellular signalling in plant innate immunity.
SUMO chain formation relies on the amino-terminal region of SCE1 and has dedicated substrates in plants.
Title: SUMO chain formation relies on the amino-terminal region of SUMO-conjugating enzyme and has dedicated substrates in plants.
Functionally similar to human SUMO2 and SUMO3, Arabidopsis SUMO1 and 2 can form chains, even though they do not possess a consensus SUMOylation motif. The surprising finding that plants have dedicated enzymes for chain synthesis implies a specific role for SUMO chains in plants
Title: SUMO Chain Formation by Plant Enzymes.
we provide evidence for the existence of a preferential conjugation of AtSUMO1/2 compared with AtSUMO3/5, which is determined by a role of the E1-activating enzyme in SUMO paralogue discrimination.
Title: Distinctive properties of Arabidopsis SUMO paralogues support the in vivo predominant role of AtSUMO1/2 isoforms.
SUMO1 becomes conjugated with ubiquitin during heat stress, showing posttranslational modifications.
Title: Proteomic analyses identify a diverse array of nuclear processes affected by small ubiquitin-like modifier conjugation in Arabidopsis.
SUM3 promotes plant defense downstream of salicylic acid, while SUM1 and SUM2 together prevent salicylic acid accumulation in noninfected plants.
Title: Arabidopsis small ubiquitin-like modifier paralogs have distinct functions in development and defense.
SIZ1-mediated conjugation of SUMO1 and SUMO2 to other intracellular proteins is essential in Arabidopsis, possibly through stress-induced modification of a potentially diverse pool of nuclear proteins.
