Other claims from this paper (5)

Observation Mlp124478 accumulated in plant nuclei and nucleoli.
Intervention effect Constitutive Mlp124478 expression repressed immune response genes in Arabidopsis.
Intervention effect Constitutive Mlp124478 expression increased waviness of Arabidopsis rosette leaves.
Observation Mlp124478 associated with the TGA1a-binding DNA sequence.
Mechanism The authors suggest Mlp124478 binds the TGA1a promoter to suppress pathogen-induced genes.
