Toxins Produced by Three Species of Seiridium Affecting Cypress Trees
Seiridium cardinale, a strain of S. cupressi (teleomorph: Lepteutypa cupressi) and S. unicorne cause canker diseases on Mediterranean cypress (Cupressus sempervirens) and other members of Cupressaceae (Graniti, 1986; Graniti and Frisullo, 1987). Besides the cankers, yellowing or reddening of the foliage and die-back frequently occur, but often in plant parts or branches distal from where the fungus can be isolated. This observation suggests that transiocatable Phytotoxins could be involved in the development of these symptoms. Therefore we have began to investigate this possibility.
