TL;DR
Blue light induces the formation of Neurospora crassa protoperithecia and the Bunsen‐Roscoe law is obeyed at the fluence of 12.6 J/m2.
Abstract
Abstract Blue light induces the formation of Neurospora crassa protoperithecia.This photoinduction is completed in less than 24 h. Its threshold is about 4.2 J/m 2 . Red light is ineffective. The Bunsen‐Roscoe law is obeyed at the fluence of 12.6 J/m 2 for fluence rates from 5.25 × 10 2 to 1.05 W/m 2 .

222 Citations1967Malcolm Sargent, Winslow R. Briggs
The expression of a circadian rhythm of conidiation by timex, a strain of Neurospora crassa, is inhibited by growth in continuous white light, and the action spectrum suggests that a carotenoid or flavin compound may be the photoreceptor, but does not allow one to determine conclusively whether the receptor is indeed a carOTenoid, flavin, or some other unrelated pigment.

The amount of carotenoids produced in Neurospora was proportional to the light dosage, and it was assumed that a flavin was the photoreceptor and no other pigments with a similar spectrum could be detected in neurospora.

An action spectrum for light-induced carotenoid biosynthesis in Neurospora crassa was determined in 4 to 20 nm steps from 260 to 800 nm, which describes a mechanism by which beta-carotene could act as a photoregulator.

Though the action spectra were not identical, the number of characters in common were suggestive of a similar photoreceptor, indicating the possibility of a singlePhotoreceptor for both sexual and asexual reproduction of P. herbarum.

The isolation and characterization of mutants that block perithecial development in Neurospora crassa are described and the significance of these results in terms of "developmental" mutants isolated in other organisms and in relation to models of eukaryotic development is discussed.

Mutants defective in polyol metabolism and/or in protoperithecial development were selected in Neurospora tetrasperma, a species in which protoperital development occurs at nonpermissively high temperature if certain polyols are used in lieu of sucrose as carbon source.

Action spectra for photoinduction of perithecia after different lengths of dark period were determined with apically growing mycelium of a sordariaceous fungus Gelasinospora reticulispora and reciprocity between intensity and exposure time was observed within the range of incident energy used.

Perithecia resulting from a single exposure of vegetative colonies to monochromatic UV in all instances developed mature asci following an additional few days of incubation in darkness, and there was no evidence that maturation of asci required an additional exposure to light.

It is indicated that carbohydrate metabolism via fermentative glycolysis functions normally in ascogonia differentiating (25°C) cultures only, and polyols, especially ribitol and xylitol utilized as sole source of carbon, induced abundant protoperithecial morphogenesis at 37°C.

The wild-type strains of Neurospora crassa first isolated by Dodge, Abbott & Chilton were found to differ in the range of temperatures over which protoperithecia were produced; similar results were obtained with two recently isolated wild strains of a species of neurospora.

Mycelia showed greatest fertility when less than 60 h old but retained overall fertility much longer, because the production of additional protoperithecia continued as mycelia aged, unless suppressed after fertilization.
