Structure and Role of a Soluble Cytoplasmic Glucan from Phytophthora cinnamomi

SUMMARY

A soluble glucan was isolated from the mycelium of Phytophthora cinnamomi and found to be a β-I →3-linked glucan with branches arising from residues substituted at both C-3 and C-6. This glucan is an important reserve material of the fungus; it accumulates in mycelium grown in glucose-rich medium and disappears upon incubation in media devoid of glucose.
