Genetic control of allelic recombination at the histidine-3 locus of Neurospora crassa.
T H E histidine-3 (his-3) locus of Neurospora crassa has aroused considerable interest because it 'controls not only the last step but also at least two early reactions in the biosynthesis of histidine (AHMED, CASE and GILES 1964; CATCHESIDE 1960, 1965). Complementation and genetic analyses of his-3 mutants, showing that noncomplemeiiting mutants, lacking all the three functions, appeared to be...
متن کاملSomatic recombination in pseudowild-type cultures of Neurospora crassa.
Populations in heterotic equilibrium show a greater percentage decrease than populations in mutational equilibrium, but the difference is very small for rare genes. Mortality and morbidity data on inbred offspring from consanguineous marriages cannot distinguish genes in one type of equilibrium from those in another. The current concept of genetic load is based on artefacts rather than on inher...
متن کاملControl of trehalase synthesis in Neurospora crassa.
When an aconidial strain (STL6A) of Neurospora crassa is grown on carbon sources such as glucose, maltose, sucrose, etc., trehalase activity per unit weight of mycelium is very low. By contrast, media containing arabinose, glutamic acid, glycine, etc., which support growth only poorly, produce mycelium with very high trehalase activity. Retarding growth limiting the supply of a necessary nutrie...
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...
متن کاملRapid genetic mapping in Neurospora crassa.
Forward genetic analysis is the most broadly applicable approach to discern gene functions. However, for some organisms like the filamentous ascomycete Neurospora crassa, genetic mapping frequently represents a limiting step in forward genetic approaches. We describe an efficient method for genetic mapping in N. crassa that makes use of a modified bulked segregant analysis and PCR-based molecul...
