These include, for example, the genes hex ‐1 of Neurospora crassa and pacC of Aspergillus nidulans, which respond to extracellular phosphate changes and ambient pH, respectively . The filamentous fungus N. crassa is a heterothallic, free‐living, eukaryotic microorganism that is widespread in nature and is clearly visible due to its. In Neurospora crassa, three transport systems have been described based on the analysis of the kinetics of amino acid uptake and the patterns of competitive inhibition between amino acids. The Gap1 homolog in Neurospora crassa is encoded by the PMG locus, which can transport all .
The pH-signaling pathway controls accumulation of the reserve carbohydrate glycogen and trehalose in Neurospora crassa. We previously identified the PAC-3 transcription factor as a putative regulator of glycogen metabolism , and later we showed that PAC-3 is required for proper glycogen accumulation by down-regulating the expression of the gene encoding glycogen synthase . The filamentous fungi display remarkable and diverse metabolic pathways and show great versatility in the utilization of sources of carbon, nitrogen, phosphorus, sulfur, and other metabolites and in acquiring essential elements, e.g., iron and potassium. This chapter emphasizes practical aspects, methods, and simple assays for investigating fungal physiology and metabolism and introduces some.
P-starved plants scavenge inorganic phosphate (Pi) by developing elevated rates of Pi uptake, synthesizing extracellular phosphatases, and secreting organic acids. To elucidate mechanisms controlling these acclimation responses in photosynthetic organisms, we characterized the responses of the green alga Chlamydomonas reinhardtii to P starvation and developed screens for isolating mutants. The relative concentrations of secreted proteins in liquid cultures of Neurospora crassa differ in constant darkness compared to constant light (lx). Light reduces the concentrations of some polypeptides markedly and increases the concentrations of protein species of 67, 40, 18 and 13 kDa. The “blind” wc-2 mutant of Neurospora does not show light dependent differences in amounts of.

J Bacteriol. A strain of Neurospora crassa defective in amino acid transport can utilize a variety of amino acids for growth when readily metabolizable nitrogen is limiting. Growth is accompanied by the production of an extracellular deaminase that converts the amino acid to its respective keto acid plus equimolar quantities of utilizable nitrogen in the.
The production of pectinase was studied in Neurospora crassa, using the hyperproducer mutant exo-1, which synthesized and secreted five to six times more enzyme than the wild-type.
A new species of orthophosphate repressible extracellular 5′-nucleotidase (5′-ribonucleotide phosphohydrolase, EC ) was found to be released into mycelial culture media when a wild type strain of Neurospora crassa was grown on limiting amounts of phosphate.

Following plant biomass pretreatment, the furan derivative furfural is present at concentrations which are inhibitory to yeasts. Detoxification of furfural is thus important for efficient fermentation.
