Immunocytochemical localization of callose in the vascular tissue of tomato and cotton plants infected with Fusarium oxysporum
Keyword(s):
Callose (β-1,3-glucan) was localized with the electron microscope in the contact cells surrounding vessels of tomato and cotton infected with Fusarium oxysporum by means of gold labelling with a polyclonal antiserum to β-1,3-glucan. The callose was deposited in the apposition layers formed after infection in the cells surrounding initially infected vessels. Callose was not detected in the contact cells surrounding secondarily infected vessels. Callose could be detected in the contact cells of resistant and susceptible tomato cultivars 4 h after inoculation. Key words: β-1,3-glucans, contact cells, gold labelling, Gossypium, Lycopersicon esculentum.
