Rice seed germination priming by salicylic acid and the emerging role of phytohormones in anaerobic germination.

This Commentary examines a recent study that identified peroxisomal cinnamate: CoA ligases as key enzymes for salicylic acid biosynthesis, which promotes submerged germination by releasing the inhibition of rice germination by indole-acetic acid. This study thus provides important information for developing rice varieties suitable for direct seeding.
