Abstract

The biosynthesis of cyclic triterpenoids in ten saponin-deficient (sad) mutant varieties of the diploid oat. Avena strigosa is reported. Two mutants were found to be deficient in 2,3-oxidosqualene:beta -amyrin cyclase (OS beta AC) (EC 5.4.99) and thus unable to produce the beta -amyrin necessary for the production of avenacins. The other mutants studied had post beta -amyrin lesions. 2,3-Oxidosqualene:cycloartenol cyclase (OSCC) (EC 5.4.99.8) needed for sterol formation was present in all ten mutants.
