MOLECULAR ANALYSIS OF THE SULFUR REGULATORY CIRCUIT OF NEUROSPORA CRASSA
The sulfur regulatory circuit of the filamentous fungus, Neurospora crassa, consists of a set of unlinked structural genes which encode sulfur catabolic and two major regulatory genes which govern their expression. The cys-3 regulatory gene encode a transacting regulatory protein which activates the expression of cys-14 and ars, whereas the other regulatory genes Scon-l and Scon-2 appear to...
متن کاملGenome-wide expression analysis of genetic networks in Neurospora crassa
The products of five structural genes and two regulatory genes of the qa gene cluster of Neurospora crassa control the metabolism of quinic acid (QA) as a carbon source. A detailed genetic network model of this metabolic process has been reported. This investigation is designed to expand the current model of the QA reaction network. The ensemble method of network identification was used to mode...
متن کاملBiotransformation of Hydrocortisone by Neurospora crassa
The ability of Neurospora crassa FGSC 4335 in the biotransformation of hydrocortisone was investigated. The microorganism produced two major metabolites after incubation with the substrate for seven days. Each microbial product was purified chromatographically and identified on the basis of spectral data. The products were identified as 11?,17?,20?,21-tetrahydroxypregn-4-en-3-one (II) and 11?-h...
متن کاملGenetic and Non-Genetic Factors in Pigmentation of Neurospora Crassa.
HE biochemical genetics of carotenoid pigments has been studied in the T tomato ( LEROSEN et al. 1941 ; MACKINNEY and JENKINS 1949 ; PORTER and LINCOLN 1950), corn (MANGELSDORF and FRAPS 1931) and red yeast (BONNER et al. 1946). HAXO (1949) worked out the carotenoid components of the wild type Neurospora. The present paper deals with genetic and biochemical studies of a modifier system for pigm...
متن کاملFixed genetic instability in Neurospora crassa.
NE of the most convincingly documented genetic phenomena is the great Ovariabi l i t y in spontaneous mutation frequencies at different genetic sites. This variability is seen most readily in BENZER’S topographic maps of the rII region of phage T4 in which the linear distributions of mutants of different origins are compared (BENZER 1961). Restricting our attention to spontaneously arising muta...
