| genetic determinants of circadian rhythmicity in neurospora. | timex, a strain of neurospora crassa which exhibits a circadian rhythm of conidia formation in growth-tube cultures, has been found to differ from wild-type strains by two genes. one gene, inv, is responsible for an invertase deficiency, whereas the second gene, bd, is of unknown function. both genes map independently from other genes known to induce neurospora rhythmicity. the inv gene is not essential for the timex phenotype because bd strains express that phenotype on certain media. although ... | 1969 | 5773032 |
| neurospora mutant exhibiting hyperproduction of amylase and invertase. | a mutant strain of neurospora crassa has been isolated which is derepressed for amylase and beta-fructofuranosidase (invertase). large amounts of the two enzymes were secreted into the culture medium upon depletion of exogenous carbon source. the resulting increases of the two extracellular enzymes were prevented by actinomycin d, cycloheximide, and glycerol. the starving cells of the mutant strain produced amylase and invertase de novo, as evidenced by incorporation of radioactive amino acids i ... | 1969 | 5773010 |

(i) the invertaseless condition was recessive in heterokaryons; (ii) no invertase inhibitor was found in m ... | 1969 | 4975154 |

| utilization of exogenous and endogenous ornithine by neurospora crassa. | through the use of a mutant deficient in ornithine-delta-transaminase (ota), it is shown that this enzyme normally has no obligate or even major biosynthetic role in neurospora. the pathways of ornithine and proline synthesis proceed wholly independently of each other in ota-less strains. it is probable that ota functions as an enzyme of arginine catabolism. with mutants affected in ota, ornithine transcarbamylase, and the synthesis of ornithine, it was demonstrated that exogenous and endogenous ... | 1968 | 5674053 |
| mutants of neurospora crassa deficient in ornithine-delta-transmainase. | the arg-12(s) mutation of neurospora causes a partial block in the ornithine transcarbamylase (otc) reaction. strains carrying this mutation will use endogenous ornithine, but not exogenous ornithine, as a precursor of arginine. certain strains carrying arg-12(s) may be used for direct selection of variants able to use exogenous ornithine as an arginine precursor. among eight such derivatives, six lacked the catabolic enzyme ornithine transaminase (ota). all six mutations were alleles of a singl ... | 1968 | 5674052 |
