The concentration of P in the growth medium had a marked effect on the amount of the fungicide phosphite accumulated by Phytophthora palmivora. The mass of mycelium, produced after 7 days growth in a medium containing excess P, was not markedly inhibited until phosphite concentrations of 10 mM or greater were supplied. In contrast, in a P-deficient medium, growth was inhibited by 0.1 mM phosphite. In the latter medium, the fungus took up significantly more phosphite once P had been depleted from the medium (from day 4 to 6). When 7 day old mycelium was presented with either 1 mM P or phosphite, the P-deficient mycelium transported either anion at almost eight times the rate found in the P-excess mycelium. The level of alkaline phosphatase present in the P-deficient mycelium was also significantly elevated. [ABSTRACT FROM AUTHOR] |
