Genetics of sordaria fimicola. i. ascospore color mutants

TLDR
A gray-spored mutant of SORDARIA FIMICOLA was obtained by means of ultraviolet irradiation, and some perithecia were produced which contained asci with four wild-type and four gray ascospores, thus making possible a direct analysis of segregation of the spore color locus in the ascus.
Abstract
SORDARIA FIMICOLA is a homothallic pyrenomycete which, like 8-spored species of Neurospora, produces asci, each with eight dark ascospores in a single orderly series. No other type of spore is produced by this species. Recently the writer (1954) obtained a gray-spored mutant by means of ultraviolet irradiation. When the mutant culture was paired with a wild-type culture, some perithecia were produced which contained asci with four wild-type and four gray ascospores, thus making possible a direct analysis of segregation of the spore color locus in the ascus. Zickler (1934) studied a similar phenomenon in the asci of the heterothallic pyrenomycete Bombardia lunata, and Bistis and Olive (1954) reported on the segregation of two different loci affecting spore color in the heterothallic discomycete Ascobolus stercorarz us.

Sexual Recombination in Gibberella zeae

Robert L. Bowden, +1 more
- 01 Feb 1999 - 
TL;DR: A method for inducing sexual outcrosses in the homothallic Ascomycete fungus Gibberella zeae (anamorph: Fusarium graminearum) was developed and development of proto-trophic wild-type colonies was taken as evidence of sexual recombination.

Heterogenic Incompatibility in Plants and Animals

TL;DR: The chapter intends to acquaint biologists not only with the existence and versatile genetic basis of heterogenic incompatibility, but also with its general importance as a basic biological phenomenon.

The Genetics of Aspergillus nidulans

TL;DR: The biochemical genetics of Aspergillus nidulans, though similar to that of Neurospora and Ophiostoma, has revealed interesting differences in detail, e.g., the inability of citrulline to replace ornithine for strains responding to Ornithine or arginine; the unable of tryptophan to replace anthranilic acid for certain strain responding to anthranic acid or nicotinic acid.

Preliminary Observations of the Chromosomes of Neurospora Crassa

TL;DR: McClintock's work on the fungus Neurospora crassa developed out of Beadle's work at Stanford University during the last several months of 1944 as discussed by the authors.

Map construction in Neurospora crassa.

TL;DR: In this paper, tetrad data from gene-centromere and gene-gene intervals have been placed on a uniform basis for mapping by computing map lengths from second-division segregation frequencies and tetratype segregation frequencies, respectively.
