Callus cultures of Cupressus lusitanica Miller which grow fast for gym
nosperm plant cells have been established and maintained for several y
ears on Gamborg B5 medium supplemented with benzylaminopurine and naph
thylacetic acid as growth regulators. De novo synthesis of beta-thujap
licin, a heart wood constituent of many Cupressaceae species, took pla
ce in the callus while being incubated for a several days after a trea
tment with culture filtrates of some fungi including wood rotting ones
or yeast extract solutions. This elicitation phenomenon was greatly r
eproducible. The elicitor in yeast extract was partially purified and
is supposed to have a molecular mass between 10 and 50 kD.
