A triple albino mutant of Neurospora crassa with a measured content of carotenoids absorbing at 470 nm less than 0.5% of that of the wild type (calculated value less than 8·10(-4)%) had the same threshold for photoinduction of protoperithecia as the wild type when illuminated with monochromatic ligh

✦ Synopsis
Nitrogen, as KNO3 or NH4NO3, can inhibit the photoinduction of protoperithecia in Neurospora crassa when present in the medium at a high concentration but does not inhibit the photoinduction of carotenoids. The point at which the presence of high nitrogen levels is no longer inhibitory is 5 h after illumination.

It is known that Neurospora crassa mycelia cultured in standard concentrations (76 to 190 #g/ml) of sulfate accumulate a low molecular weight inhibitor of tyrosinase (monophenol, dihydroxyphenylalanine: oxygen oxidorenductase; EC 1.14.1.18.1.). This is not observed in cultures grown under sulfate-li
The mitochondrial cytoehrome spectrum of the poky strain of Neurospora crassa and its variation during the life cycle have been analyzed. Two factors are taken into account in addition to those usually considered," absorption in the near-ultraviolet Soret region and the physical nature of the electr
Growth of Neurospora crassa on media containing NH4+ leads to the repression of a variety of permeases and alternative pathways which would generate NH4+, so called "ammonium repression." The mutant am2 which lacks NADP-GDH is not subject to ammonium repression of nitrate reductase or urea permease,
