Research Abstract	We focused on the role of constitutive resistance in the reproduction of kelp, particularly Saccharina japonica. It has been suggested that sori (reproductive organ in the sporophyte) have a high phenolic compound content and that they are protected by the release of iodine and radical oxygen species to combat biotic stresses. Silicon deposition is also considered to provide constitutive resistance in kelp sori. These phenomena suggest that wound-healing and kelp reproduction are supported by both constitutive and induced resistance mechanisms, and that silicon and phenolics deposition might contribute as protectants to the success of kelp reproduction.
