Phytoalexin production, /?-glucan

Glucan Elicitors of Phytoalexin Production. Phytoalexins are post-infection toxins formed de novo by the host. [Pg.128]

The observations that the phytoalexins phaseollin (92) and pisastin (93) have injurious effects on plant plasma membranes suggests that wilting observed in some plant diseases could be an indirect result of phytoalexin production. Whether this occurs in the case of 3-glucan-induced wilting of Eucalyptus species is not known since phytoalexins have not been reported from eucalypts. However the dose of polysaccharide needed to produce the maximum phytoalexin response in the soya bean hypocotyl test systems (84) is an order of magnitude lower than that required for wilt-induction in the seedling assays (50). [Pg.130]
