Conidiation in N. crassa can be either induced or suppressed by altering the growth media. When grown in standing cultures, strain Lind+ forms about 105 conidia per ml of medium. This conidial production occurs during the second to fifth day. The leve . . .

Cultures of a serine auxotroph of Neurospora crassa, ser (JBM 4-13), demonstrate a high frequency of spontaneous reversion to prototrophy. This study examines two questions: First, whether the phenomenon of spontaneous reversion occurs in all vegetati . . .

The serine auxotroph, ser (JBM 4-13), appeared to be highly unstable and displayed a highly variable revertant frequency of 1 x 10-6 to 2.8 x 10-1. The mutant's characteristics were examined with respect to the properties of unstable genes predicted b . . .

A newly isolated serine auxotroph of Neurosporacrassa, ser (JBM 4-13), exhibited a high rate of reversion in mapping experiments. This study sought to determine whether reversion occurred at a specific frequency , and whether it was time dependent. In . . .

Two pathways for serine biosynthesis in Neurospora crassa have been reported by Sojka and Garner. The phosphorylated pathway involves 3-phosphoglyceric acid, phosphohydroxypyruvic acid, and phosphoserine as intermediates, whereas the non-phosphorylate . . .

Three strains of Neurospora crassa were used to correlate lipid metabolism with formation of conidia. Lindegren+, a wild type strain forms conidia when grown on C medium but forms no conidia or aerial hyphae when grown on M medium. During the period o . . .

A serine auxotroph of Neurospora crassa, ser (JBM 4-13), exhibits genetic instability, reverting to prototrophy at high frequency. This study examines reversion in a mutant stock and the genetic behavior of serine-independent cultures derived from tha . . .

The effect of pH on the hydrolysis of phosphoserine by enzymes extracted from Neurospora crassa was found to be different for wild type than for the serine requiring mutant ser(JBM-5). The pH profile of activity in ser(JBM-5) extracts lacks a shoulder . . .
