title: Accumulation of isoflavones and pterocarpan phytoalexins in cell suspension cultures of different cultivars of chickpea (Cicer arietinum).
abstract: Cell suspension cultures of chickpea (Cicer arietinum L.) were established from cultivars ILC 3279 and ILC 1929, resistant and susceptible towards the chickpea pathogenic fungus Ascochyta rabiei. The two cell culture lines possess identical growth properties and show high accumulation of the isoflavones biochanin A and formononetin together with their glucoside and malonylglucoside conjugates. The cultures of the two cultivars, however, significantly differ in their accumulation of the phytoalexins medicarpin and maackiain essentially as previously demonstrated for the plant genotypes. Phytoalexin formation was elicited by using yeast extract as an inducing agent.
