Method of Screening for Plant Defense Activators, Plant Defense Activators, and Method of Enhancing Immune Response

摘要

A method of screening for a plant defense activator, which enhances an immune response of a plant, from at least one candidate substance includes: contacting a plant cell in which a jasmonic acid-dependent defense pathway and a salicylic acid-dependent defense pathway of a plant defense system are capable of working independently from each other, with a candidate substance; contacting the plant cell with a trigger material that induces an immune response; and assaying the plant cell after contacting with the trigger material based on an index representing an immune response, to select a target substance that enhances an immune response of the plant. A method of enhancing an immune response of a plant includes use of a specific compound, and a plant immune response enhancer includes the specific compound.

1. A method of screening for a plant defense activator, which enhances an immune response of a plant, from at least one candidate substance, the method comprising:
contacting a plant cell in which a jasmonic acid-dependent defense pathway and a salicylic acid-dependent defense pathway of a plant defense system are capable of working independently from each other, with a candidate substance; contacting the plant cell with a trigger material that induces an immune response; and assaying the plant cell after the contacting with the trigger material based on an index representing an immune response, to select a target substance that enhances an immune response of the plant based on a result of the assaying based on the index representing an immune response, wherein the plant cell is a cultured plant cell that produces no salicylic acid or produces an amount of salicylic acid insufficient for inhibiting the jasmonic acid-dependent defense pathway when the immune response is induced.
