Direct fungicidal activities of C6-aldehydes are important constituents for defense responses in Arabidopsis against Botrytis cinerea

Fungicidal activities of C6-aldehydes, such as (Z)-3-hexenal, (E)-2-hexenal, and n-hexanal, formed by hydroperoxide lyase are found to be one of most important components for the defense against necrtrophic fungal pathogen, Botrytis cinerea, in Arabidopsis.
