Induction and secretion of RNA-degrading enzymes by phosphate deficiency in Pholiota nameko.
Changes in activity of RNA-degrading enzyme and amounts of phosphorus in mycelia and culture filtrate during Pi-sufficient and -deficient cultures of Pholiota nameko were investigated. The results showed that the intracellular and extracellular activities are controlled by the Pi concentration in the medium. Moreover, the induction and secretion of RNA-degrading enzymes under the Pi-deficient condition were analyzed by activity staining.
