Lg. Willoughby et Rj. Roberts, LOSS AND RECOVERY OF ZOOSPORE MOTILITY IN AN ISOLATE OF APHANOMYCES FROM A DISEASED FISH, Mycological research, 98, 1994, pp. 1463-1464
Zoospores of an Aphanomyces from a diseased fish ceased to be motile f
ollowing physical shock, or ionic shock with 100 mg Ca l(-1), but moti
lity was regained after 4.5 h, without an intervening encystment phase
. This novel finding indicates that, in this fungus at least, zoospore
s might be transported, immobile, by water currents and encyst only in
response to conducive surfaces.
