Summary
When Agrobacterium rhizogenes transformed root cultures of Lotus corniculatus were treated with glutathione, isoflavan phytoalexins accumulated in both tissue and culture medium. This accumulation of phytoalexins was preceded by a transient increase in the activity of phenylalanine ammonia lyase (PAL). Elicitation of PAL occurred throughout the growth curve of Lotus ‘hairy roots’ and in different sectors of transformed root material.
