Genetic Control of Biochemical Reactions in Neurospora
TLDR
In investigating the roles of genes, the physiological geneticist usually attempts to determine the physiological and biochemical bases of already known hereditary traits, establishing that many biochemical reactions are in fact controlled in specific ways by specific genes.
FOOD LEVEL IN RELATION TO RATE OF DEVELOPMENT AND EYE PIGMENTATION IN DROSOPHILA MELANOGASTER
TLDR
If deprived of food during a portion of the larval developmental period after the 70-hour change, the final size attained by the fly appears to depend largely on the proportion of this period spent on full food.
Gene Recombination in Escherichia Coli
ANALYSIS of mixed cultures of nutritional mutants has revealed the presence of new types which strongly suggest the occurrence of a sexual process in the bacterium, Escherichia coli.
Genic Control of Biochemical Reactions in Neurospora
TLDR
There is recorded in the literature a sufficient number of instances of mutations affecting the normal biochemistry of the organism to indicate that the gene exercises an important function in metabolism, and this aspect of the general problem is the subject of the discussion this afternoon.
Gene Recombination in the Bacterium Escherichia coli
TLDR
This paper will be devoted to the presentation of evidence for the occurrence in a bacterium of a process of gene recombination, from which the existence of a sexual stage may be inferred.
THE TUBE METHOD OF MEASURING THE GROWTH RATE OF NEUROSPORA
TLDR
A "growth tube" assay of yeast extract for p-aminobenzoic acid has been made to indicate in principle how mutant strains might be used in bioassay work, and attention has been directed particularly to such factors as might be expected to affect the method in this application.
Relationship of the Major Constituents of the Neurospora crassa Cell Wall to Wild-Type and Colonial Morphology
TLDR
The relationship of cell wall to morphology in Neurospora crassa was studied by correlating the levels of structural polymers of the cell wall with wild-type and colonial morphology.
Biochemical Mutant Strains of Neurospora Produced by Physical and Chemical Treatment
TLDR
Here the admittedly spurious specific epithet, "P. hybrida" (which would imply the presence of a natural species), would be transferred to the category of hybrid-group (grex-hybrida), signifying a group of garden hybrids with a presumed common set of ancestors.
