Abstract:
Phytotoxins produced by a strain of Verticillium dahliae pathogenic on potato have been purified from culture fluids and xylem extracts of potato stems infected by the fungus. The toxins were very similar to each other in molecular mass (approximately 1000 D), HPLC profile, amino acid composition, biological activity and antigenic cross-reactivity. Visible Verticillium wilt symptoms were observed when either peptide, in amounts as low as 20 ng (2 × 10-6 mol), was injected into detached potato leaves. The differential activity of the peptides on hosts and non-hosts of the fungus, as well as on susceptible and tolerant cultivars, indicated host specific properties. An immunofluorescence assay detected the toxin in potato stems before extensive colonization occurred, suggesting that the toxin may be translocated in advance of the growing hyphae. © 1989.
