Salicylic acid (SA) is a plant defense hormone required for immunity. Arabidopsis NPR1 and
NPR3/NPR4 were previously shown to bind SA and all three proteins were proposed as SA …

The plant defense hormone salicylic acid (SA) is perceived by two classes of receptors,
NPR1 and NPR3/NPR4. They function in two parallel pathways to regulate SA-induced …

Salicylic acid (SA) is a key plant hormone required for establishing resistance to many
pathogens. SA biosynthesis involves two main metabolic pathways with multiple steps: the …
