Abstract
Abstract A 10-day time-course study on the production of 2,7-dihydroxycadalene, 2-hydroxy-7-methoxycadalene, lacinilene C and lacinilene C 7-methyl ether in cotton leaves induced by cell-free mycelial extracts of Aspergillus flavus showed that the cadalenes and the lacinilenes accumulate in a cyclic fashion. The initial increase at 2 days is followed by a greater increase at 6 days after treatment. The location of these compounds was found predominately either in a 6 mm wounded, treated area or in a 3 mm area immediately surrounding the 6 mm treated area of the leaf. Lacinilene C and lacinilene C 7-methyl ether were both phytotoxic in a Lemna minor bioassay. Endogenous constituents produced by plant cell damage could have triggered the production of the cadalenes and lacinilenes observed.
