Suppressed recombination and a pairing anomaly on the mating-type chromosome of Neurospora tetrasperma.
Neurospora crassa and related heterothallic ascomycetes produce eight homokaryotic self-sterile ascospores per ascus. In contrast, asci of N. tetrasperma contain four self-fertile ascospores each with nuclei of both mating types (matA and mata). The self-fertile ascospores of N. tetrasperma result from first-division segregation of mating type and nuclear spindle overlap at the second meiotic d...
متن کاملExpression of meiotic drive elements Spore killer-2 and Spore killer-3 in asci of Neurospora tetrasperma.
It was shown previously that when a chromosomal Spore killer factor is heterozygous in Neurospora species with eight-spored asci, the four sensitive ascospores in each ascus die and the four survivors are all killers. Sk-2K and Sk-3K are nonrecombining haplotypes that segregate with the centromere of linkage group III. No killing occurs when either one of these killers is homozygous, but each i...
متن کاملCrosses Heterozygous for Hybrid Neurospora Translocation Strains Show Transmission Ratio Distortion Disfavoring Homokaryotic Ascospores Made Following Alternate Segregation
By introgressing Neurospora crassa translocations into N. tetrasperma, we constructed heterokaryons bearing haploid nuclei of opposite mating types, and either the translocation and normal sequence chromosomes (i.e., [T + N]) or a duplication and its complementary deficiency (i.e., [Dp + Df]). The [T + N] heterokaryons result from alternate segregation of homologous centromeres, whereas adjacen...
متن کاملChanges in the Permeability of Ascospores of Neurospora Tetrasperma during Germination
The respiration and germination of activated ascospores of Neurospora tetrasperma have been shown to be almost completely inhibited by concentrations of ethylene diaminetetraacetic acid (EDTA) as low as 0.0035 M. In contrast, however, dormant ascospores are insensitive to this chelating agent. At any time up to about 150 minutes after activation Ca(++) or Mg(++) can completely reverse this toxi...
متن کاملLinkage group establishment in Neurospora tetrasperma by interspecific hybridization with N. crassa.
HE purpose of this paper is to provide evidence for the establishment of one Tor more genetic markers on seven linkage groups in Neurospora tetrasperma so as to enhance the usefulness of this species in genetic research. The linkage groups were determined by hybridization with the genetically well known species, N . crmsa. Markers were first transferred from one Neurospora species to another by...
متن کاملMechanisms of protection of trehalase against heat inactivation in Neurospora.
The half-life of trehalase and invertase at 65 and 60 C was found to be much greater when intact ascospores of Neurospora tetrasperma were heated, as compared with extracts. By contrast, no protection was afforded these enzymes when they were heated in intact conidia and mycelium of N. crassa or N. tetrasperma. The protective effect of ascospores for trehalase was further investigated by heatin...
