| Abstract/Contents: | Root-inducing (Ri) T-DNA transformed roots of carrot were uses as the plant partner in a study of 32P absorption and plasmalemma ATPase activity in the hyphae of the vesicular-arbuscular mycorrhizal fungus Gigaspora margarita Becker & Hall. Hyphae from germanating spores were grown in the presence or absence of root exudates and volatiles. In the presence of these root factors, 32P isotope labelling occurred in hyphae, auxillary cells and spores, while in the absence of these factors, the labelling only occurred in fungalle in the absence of these factors, the labelling only occurred in spores. Similarly, ATPase activity appeared on the fungal plasmalemma only in the presence of root factors. The use of the ATPase inhibitor, diethylstilbestrol, demonstrated the importance of plasmalemma ATPase in the stimulation of hyphal growth of this obligately biotrophic fungus. |
