“…In contrast to other strains, C. albicans 1001 gave rise to morphological mutants in which a permanent pseudomycelial appearance was associated with a rough colonial morphology. Our mutants seem to be different from the pseudomycelial variant described several years ago (Nickerson & Chung, 1954;Ward & Nickerson, 1957;Nickerson, 1963). This variant appeared spontaneously and its morphology was affected by the presence of a diffusible substance produced by cultures of the wild-type, which seemed to be cysteine.…”

“…As has been recently pointed out by Nickerson & Bartnicki-Garcia (1964), the changing composition of the cell wall can influence cell morphology. It is possible that the in the C/M system the changes produced by a change in nitrogen source influence production or physical state of some cell-wall component which is essential for the hyphae to break through the liquid surface and giye rise to conidia.…”

SUMiMARYTwo distinct forms of growth of wild-type Neurospora crassa can be produced by altering the nitrogen source of the growth medium. One form completely lacks conidia and carotenoids ; the other exhibits enhanced conidiation and pigmentation. Analysis of the oxidative and glycolytic metabolism of these two forms showed that the non-conidiating cultures had significantly greater glycolytic activity than the conidiating cultures, as measured by the production of ethanol, the presence of ethanol dehydrogenase and pyruvate decarboxylase activity and the response of the two culture types t o glycolytic inhibitors. When glycolysis was inhibited, conidiation occurred. When oxidative metabolism in normally conidiating cultures was interfered with conidiation was suppressed. These results suggest that the relative activities of fermentative and oxidative pathways in the cell regulate both conidiation and pigment synthesis. The most probable point at which this control is exercised is a t the stage of pyruvate, the common branch point of these two pathways. Conidiating cultures also were found to have very high NADP nucleotidase activity, while purely mycelial cultures were essentially devoid of this enzyme. An electron microscope examination of these two culture types revealed differences in cell-wall composition, in the distribution of osmiophilic granules within the cytoplasm and in mitochondria1 structure.

“…The effect of sulphur-containing amino acids on vegetative form changes in fungi has been shown by Nickerson & Falcone (1956), Nickerson (1963) and Nickerson & Bartnicki-Garcia (1964). A stimulatory effect of sulphur-containing amino compounds on the formation of the perfect stage of Aphanomyces root rot has been also shown (Papavizas & Davey, 1963).…”

SUMMARYThe sulphur-containing amino acids L-cysteine, L-cystine, L-methionine, L-homocysteine thiolactone, L-homocystine and glutathione at to 1 0 -5~ inhibited sclerotial formation without inhibition of mycelial growth and induced basidia formation in the fungus Sclerotium roEfsii Sacc. Higher concentrations inhibited linear growth and production of sclerotia. The effect of L-cysteine was competitively antagonized by iodoacetic acid at a molar ratio of 30 : 1. Iodoacetic acid induced sclerotial formation at 3 x to ~o -~M , sclerotia being produced in circles around inoculation point. The possible role of -SH groups in the morphogenesis of S . rolfsii is discussed.
