Adhesion of germlings of Botrytis cinerea
Article Abstract:
Examination of delayed adhesion, the second stage of adhesion associated with the adhesion of conidia and germlings of the facultative plant parasite Botrytis cinerea, reveals that it involves secretion of an ensheathing film. Microscopic studies of the fungal sheaths reveal that it is 25 to 60 nanometer thick in the region close to the germ tubes. Boiling or enzyme action fails to remove the germling from the fungal sheath, while NaOH easily removes the germlings. Analysis of the base-soluble material reveals the presence of glucose, protein and galactosamine.

Composition and enzymatic activity of the extracellular matrix secreted by germlings of Botrytis cinerea
Article Abstract:
Research was conducted to examine the composition and enzymatic activity of the extracellular matrix secreted by germlings of Botrytis cinerea. Samples derived by growing germlings on a glass surface were used to ascertain the composition of the ensheathing film. Results reveal cellulase, pectin lyase and pectin methyl esterase activities with both unheated and heated extracellular matrix preparations while no proteinase activity was noted.

Adhesion of nongerminated Botrytis cinerea conidia to several substrata
Article Abstract:
The results of studies of the adhesion process exhibited by the nongerminated conidia of Botrytis cinerea is described. Immediately upon hydration, conidia of the plant pathogenic fungus Botrytis cinerea adheres to the tomato cuticle and to certain other substrata. Hydrophobic interactions between the conidia and substratum is partly responsible for the immediate adhesion of conidia of B cinerea.
