Changes in fatty acid composition of Neurospora crassa accompany sexual development and ascospore germination.
Fatty acid composition was determined during several stages of sexual development in Neurospora crassa. Triacylglycerol was the predominant acyl lipid in cultures undergoing sexual development. The absolute amounts of triacylglycerol in fertilized cultures varied over time, in contrast to control (unfertilized or mock-fertilized) cultures, in which the amount of triacylglycerol decreased linear...
متن کاملRepressible cation-phosphate symporters in Neurospora crassa.
The filamentous fungus Neurospora crassa possesses two nonhomologous high-affinity phosphate permeases, PHO-4 and PHO-5. We have isolated separate null mutants of these permeases, allowing us to study the remaining active transporter in vivo in terms of phosphate uptake and sensitivity to inhibitors. The specificity for the cotransported cation differs for PHO-4 and PHO-5, suggesting that these...
متن کاملAdaptive changes in phosphate uptake by the fungus Neurospora crassa in response to phosphate supply.
The phosphate uptake rate of Neurospora crassa germlings growing exponentially in media containing phosphate at concentrations between 10 mM and 50 micronM was virtually constant. The uptake characteristics of these germlings were studied in detail assuming the simultaneous operation of two uptake systems, one of low affinity and one of high affinity. The Km of the low-affinity system was const...
متن کاملNucleotide Composition of Ribonucleic Acid from Neurospora Crassa.
Henney, H. (The University of Texas, Austin) and R. Storck. Nucleotide composition of ribonucleic acid from Neurospora crassa. J. Bacteriol. 85:822-826. 1963.-The nucleotide composition of total, ribosomal, and soluble ribonucleic acid (RNA) from the conidia and the hyphae of Neurospora crassa was determined. The corresponding RNA classes from the two morphological types had the same base ratio...
متن کاملRegulation of phosphate metabolism in Neurospora crassa: identification of the structural gene for repressible acid phosphatase.
A mutant of Neurospora crassa with an altered repressible acid phosphatase has been isolated. The enzyme is much more thermolabile than that of wild type, and has an increased Michaelis constant. Tests of allelic interactions (in partial diploids) and in vitro mixing experiments were consistent with the mutation being in the structural gene for the enzyme. This gene, pho-3, was found to be loca...
