Mistranslation and Ageing in Neurospora
Nature, 1970ORGEL1 has proposed that cellular senescence could be attributed to an accumulation of errors in the protein synthesizing machinery of cells. Slight alterations in the structure of enzyme proteins involved in biosynthetic pathways might not have any major effect and might, at worst, be expected to reduce the metabolic efficiency by a fixed amount2,3 ...

Conidiation in Neurospora crassa
Archiv f�r Mikrobiologie, 1971Conidiation in Neurospora crassa has been studied in vivo by time-lapse microphotography and shown to be most generally (in aerial, “dry” conditions) a budding-fission process. Such a two-phase process is characterized by an initial basifugal budding of proconidial elements which are then secondarily separated as maturing conidia by interconidial septa.

Abstract Uricase from Neurospora crassa has been purified 400-fold. The properties of this enzyme are similar to those of the animal uricases except that it is more soluble at low pH values. Addition of uric acid to the growth medium causes a twofold increase in the amount of enzyme. One atom of oxygen is consumed per mole of uric acid decomposed in

Publisher Summary Neurospora is a valuable experimental organism for studying transport processes as its growth medium is simple, requiring only inorganic salts, a carbon source, and biotin. Many nutrilite transport systems in Neurospora have been characterized with respect to kinetic properties and genetic regulation.

9 Quelling in Neurospora crassa [PDF]
, 2002 The first report of silencing in the vegetative phase of growth in fungi was made in Neurospora crassa. A loss of hygromycin resistance was observed as a result of transformation with a plasmid carrying the bacterial hygromycin phosphotransferase ( hph ) gene, fused to the promoter of the trpC gene of Aspergillus nidulans.

The utilization of tryptophan by neurospora
Biochimica et Biophysica Acta (BBA) - General Subjects, 1965Abstract When Neurospora grows in media supplemented with tryptophan, 70–90% of the supplied tryptophan is converted in a series of reactions to anthranilic acid or derivatives of anthranilic acid. In certain strains (those blocked between shikimic acid and anthranilic acid), these reactions, coupled with the biosynthetic reactions, constitute a ...

Many advances, particularly in molecular techniques, have transformed work on Neurospora crassa. All areas of biological research have felt their impact. These include the areas of basic genetics begun by Dodge, Lindegren, and the Beadle and Tatum group prior to 1955 (Horowitz 1991); biochemical genetics, enzymology, and morphogenesis between 1945 and ...

Conidiation of Neurospora crassa
Nature, 1966THE vegetative mycelium of Neurospora crassa can, during the course of its development, successively initiate three types of reproductive structure. These are the macroconidia, microcoriidia and ascogonia which develop into protoperithecia and, after fertilization, into perithecia with ascospores. Problems of macroconidial differentiation (conidiation)

The Chromosomes of Neurospora Tetrasperma
Mycologia, 1946A comparison of McClintock's recent report (1945) on the structure and number of chromosomes in Neurospora crassa Shear & Dodge with earlier studies on this and related species brings out the possibility that significant variation exists in the morphology of the chromosomes of this genus. The present widespread interest in the physiological genetics of

Polygenic Inheritance in Neurospora
Nature, 1955ASCOSPORES of Neurospora crassa two to three times the normal size occur in many strains, though the frequency is low, probably less than one per thousand ascospores. A particular cross made in this laboratory produced an abnormally high frequency of giant ascospores (about 3.4 per cent), and since a number of these germinated and gave good cultures, a
