Non-Random Crossing over in the Second Chromosome of Neurospora Crassa.
YTOLOGICAL analysis (LINDEGREN and RUMANN, in press) has C shown that Neurospora crassa probably contains nine chromosomes. These chromosomes were found to contain respectively, 29, 18, 13, 9, 5 , 3, 3, 2, and I chromomeres; but since they were not completely uncoiled, the number of ultimate chromomeres is probably at least twice as great. They are certainly the smallest chromosomes in which cr...
متن کاملDouble Crossing over in Neurospora.
CROSSOVER involves exchange of genetic material between only two of the A four products of meiosis. We should like to know whether there are any special properties of these two strands of the tetrad which enable them to participate in crossing over. Such knowledge might help us understand the mechanics of the crossing over process and would perhaps shed some light on the physical nature of the ...
متن کاملMOLECULAR 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 کاملCharacterization of chromosome ends in the filamentous fungus Neurospora crassa.
Telomeres and subtelomere regions have vital roles in cellular homeostasis and can facilitate niche adaptation. However, information on telomere/subtelomere structure is still limited to a small number of organisms. Prior to initiation of this project, the Neurospora crassa genome assembly contained only 3 of the 14 telomeres. The missing telomeres were identified through bioinformatic mining o...
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...
