Heterogeneity and Developmental Alteration of Esterase Isoenzymes in Conidial Germination of Neurospora crassa

The Guanine Nucleotide Exchange Factor RIC8 Regulates Conidial Germination through Gα Proteins in Neurospora crassa

Heterotrimeric G protein signaling is essential for normal hyphal growth in the filamentous fungus Neurospora crassa. We have previously demonstrated that the non-receptor guanine nucleotide exchange factor RIC8 acts upstream of the Gα proteins GNA-1 and GNA-3 to regulate hyphal extension. Here we demonstrate that regulation of hyphal extension results at least in part, from an important role i...

Long-oligomer microarray profiling in Neurospora crassa reveals the transcriptional program underlying biochemical and physiological events of conidial germination

To test the inferences of spotted microarray technology against a biochemically well-studied process, we performed transcriptional profiling of conidial germination in the filamentous fungus, Neurospora crassa. We first constructed a 70 base oligomer microarray that assays 3366 predicted genes. To estimate the relative gene expression levels and changes in gene expression during conidial germin...

Neurospora crassa Hyphal Fusion in Pathway during Conidial Germination and Role of a Mitogen-Activated Protein Kinase

Chemical Activation of Ascospore Germination in Neurospora crassa.

In the red bread mold Neurospora crassa as in other pyrenomycetes the sexual spores, the ascospores, germinate only after the application of heat (Shear and Dodge, 1927; Goddard, 1935, 1938, 1939). When treated at a temperature of from 50 to 60 C for periods varying from 10 to 60 minutes the spores will germinate up to 100 per cent. Germination may occur without this treatment, the percentage d...

Structural genes for DAHP synthase isoenzymes in Neurospora crassa.

-DEoxY-D-arabino-heptulosonate 7-phosphate synthase (DAHP synthase) is 3 the first enzymic function specific to aromatic biosynthesis. In Neurospora crassa, there are three DAHP synthase isoenzymes, each subject to feedback inhibition by one of the three aromatic amino acids (DOY 1968, 1970; JENSEN and NASSER 1968) : phenylalanine (Phe), tyrosine (Tyr), and tryptophan (Trp) . Mutations inactiva...
