Ultraviolet-sensitive mutants in Neurospora crassa.
ADIATION-SENSITIVE mutants in bacteria have been reported repeatedly in recent years (s,ee SETLOW 1966). Several loci concerned with sensitivity have been mapped. Some of these mutants not only lacked the ability to repair damaged DNA but also failed to undergo genetic recombination (CLARK and MARGULIES 1965; HOWARD-FLANDERS and THERIOT 1966; VAN DE PUTTE et al. 1966). Among the eucaryotic orga...
متن کاملMutants affecting thymidine metabolism in Neurospora crassa.
When (14)C-thymidine labeled only in the ring is administered to Neurospora crassa, the majority of the recovered label is found in the ribonucleic acid (RNA). Three mutants were isolated in which different steps are blocked in the pathway that converts the pyrimidine ring of thymidine to an RNA precursor. Evidence from genetic, nutritional, and accumulation studies with the three mutants shows...
متن کاملMutants of Neurospora deficient in aryl sulfatase.
HERE has been much progress in understanding the control of protein synin Enterobacteria and their associated phages, and the operon model of control can be considered well established for several systems (EPSTEIN and BECKWITH 1968). However, it remains problematical whether this model adequately describes control processes in eucaryotes. Much of our limited insight into this problem is derived...
متن کاملReversion of aryl sulfataseless mutants of Neurospora.
I N previous publications from this laboratory, we have described two loci, called cys-3 and eth-lr, that control a family of enzymes of sulfur anabolism in Neurospora ( MARZLUF and METZENBERG 1968; METZENBERG 1968). These could be viewed as regulatory genes in search of a locus to control, since no proven structural mutants for any of the regulated enzymes were available. KERR and FLAVIN (1970...

in the progenies. This result was offered in support of a two-phase model of crossing-over. Preliminary observations of the present authors had shown that aging had little or no effect at the late developmental stages at which somatic crossing over occurs, and, in an extensive series of tests, Schwartz's experimental findings were not confirmed. These results do not disprove the two-phase hypot...
