Description

9(S)-HOTrE is a monohydroxy polyunsaturated fatty acid produced by the action of 5-lipoxygenase on α-linolenic acid.1 9(S)-HOTrE is predominantly localized in cellular ester lipids of Glechoma hederacea leaves and is partially released during artificial dehydration.2 The biological role of 9(S)-HOTrE in G. hederacea leaves is still undetermined, but it may play a role in natural senescence.2 9(S)-HOTrE is an inhibitor of spore germination and germ tube elongation of rice blast fungus with ED50 values of 45 and 30 ppm, respectively.3
