Summary, etc. A new biosynthetic intermediate of ABA, (2Z,4E)-?-ionylideneacetaldehyde, was isolated from young mycelia of Cercospora cruenta. Under an 18O2 atmosphere, an oxygen atom of this endogenous aldehyde was exclusively labeled. Similarly, three 18O atoms were incorporated into the ABA molecule recovered after prolonged incubation; selectively labeled were one of the carboxyl oxygen atoms and the two on the ring portion of ABA. A feeding experiment with [1-13C]glucose proved the exclusive operation of the mevalonate pathway for the formation of both ABA and ß-carotene. These results suggest that (2Z,4E)-?-ionylideneacetaldehyde can be a key ABA biosynthetic intermediate formed by the oxidative cleavage of a carotenoid precursor. Key words: abscisic acid; (2Z,4E)-?-ionylideneacetaldehyde; carotenoid pathway; mevalonate pathway; Cercospora cruenta
