Influence of phosphate on development of the nematode-trapping fungus Arthrobotrys oligospora.
Arthrobotrys oligospora captures and digests nematodes by means of adhesive networks. These traps are formed in the presence of nematodes but can also be induced by low nutrient media containing amino acids. Influence of phosphate on growth and development of A. oligospora was studied in a liquid culture system known to allow heavy trap formation. Substrate-induced but not nematode-induced trap, formation was inhibited by phosphate at concentrations above 30 mu M. High numbers of chlamydospores were formed in aging cultures irrespective of phosphate concentration.
