ABSTRACT
1. Even though altered forms of acid phosphatase II were wynthesixed by the mutant strains nuc-1A and nuc-2A of N. crassa, their synthesis was independent of exogenous phosphate concentratiosn. 2. Synthesis of acid phosphatase I by nuc-2A was also insensitive to exogenous phosphate concentrations. When nuc-1A was grown on a low-phosphate medium, it also produced a heat-labile acid phosphatase in addition to a I-like acid phosphatase. I-like acid phosphatase was not detected in the mycelium of the preg*c mutant strain grown on low-phosphate medium. 3. These results are consitent with participation of the nuc-2, preg and nuc-1 genes in regulating the transport and/or secretion of acid phosphatase and probably other phosphatases by Neurospora crassa
