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.
