Dityrosine, a dimeric amino acid formed by the oxidative coupling of two tyrosine residues, was found in egg shells, cyst walls and juveniles of the plant-parasitic nematodes Globodera rostochiensis, G. pallida and Heterodera avenae. Trityrosine (= tertyrosine) and tetratyrosine were also present. A proportion of the cyst protein that was insoluble in sodium dodecyl sulphate and mercaptoethanol was solubilised by treatment with sodium chlorite under conditions shown to cause complete destruction of dityrosine. We suggest that dityrosine and its higher homologues act as inter-polypeptide bridges, responsible for cross-linking cyst and egg-shell proteins. We also discuss the significance of such cross-links for the resistance of nematode eggs to environmental hazards, including fungal parasites.
