In Vivo Characterization of NADPH: 2′-Hydroxyisoflavone Oxidoreductase in Elicitor Treated Chickpea Cell Cultures and Stereochemical Aspects of the Phytoalexins Medicarpin and Maackiain

Pterocarpan phytoalexins such as medicarpin, maackiain, phaseollin, pisatin or the various isomers of glyceollin are antimicrobial compounds synthesized by plant species of the Leguminosae in response to stress, primarily caused by fungal infection (Dixon 1986, Ebel 1986).
