Allomyces Macrogynus

Allomyces macrogynus synthesized trehalose but did not appear to metabolize it. Trehalose was released to the suspending medium before the development of zoosporangia by plants suspended in water and before the development of resistant sporangia by plants in glutamic acid and glucose solution. Plants in the latter solution accumulated high levels of glycogen and trehalose before mRNA was transcribed for the development of resistant sporangia. Before the transcription of mRNA for either zoosporangia or resistant sporangia there was a period during which the plant content of glycogen, trehalose, protein and nucleic acid was constant. The increase in wall glycans and chitin during the development of zoosporangia was measured and possible origins of the walls are discussed.

Allomyces macrogynus plants were induced to make either zoosporangia in distilled water or resistant sporangia in a solution of glucose and glutamic acid. Analyses during the stages of developmentJ showed that plants of both series degraded nucleic acid, releasing uracil, hypoxanthine and guanin~ to the suspending medium. Plants in distilled water released inorganic phosphate to the medium while those in glucose-glutamic acid solution conserved the phosphate as bound phosphate. A. arbuscula also released the purines and pyrimidines.

Nucleic Acid Assays

Synchrony of duplication cycles in Allomyces macrogynus was maintained through five cycles to the end of vegetative growth. In a culture in which hyphal emergence was inhibited the fourth cycle was abnormal. No DNA synthesis occurred before septation when zoosporangia developed in culture medium. When organisms were induced to make sporangia by transfer to water there was a small apparent increase in DNA prior to but not after septation. The unavoidable extraction of wall glycopeptide poses some problems in nucleic acid assays. Partial inhibition by 10�M benomyl allowed continued growth with large rhizoids at every apex. Partial inhibition by mitomycin allowed continued growth without any further morphological differentiation.

Corynebacterium Sepedonicum

The nutritional requirements of Corynebacterium sepedonicum (Spiek. and Kott.) Skapt. and Burkh. were investigated by the use of the Warburg respiration apparatus. Pantothenic acid, in a concentration of 600 micrograms (μgm.) per liter, caused the greatest growth augmentation of nine vitamins tested. The amino acids, glutamic acid, asparagine, leucine, and lysine in concentrations of 0.001, 1. 0, 0.03, and 0.03 gm. per liter respectively, caused a marked increase in oxygen uptake, either individually or in combination. Yeast nucleic acid and thymonucleic acid had no significant effect on the growth rate of C. sepedonicum. A new medium was prepared for the isolation and maintenance of C. sepedonicum.

Trehalose Synthesis

Oxine is an inhibitor of growth and differentiation in A. macrogynus. Growth was inhibited by as little as 4 Jlg/ml and the first effect observed was inhibition of nucleic acid synthesis, followed by inhibition of protein synthesis. Consistent inhibition by oxine of the development of zoosporangia in starving plants required a concentration of 60 Jlg/m!. The degradation of RNA, always observed in starving plants, continued in the presence of oxine, showing that this is an independent phenomenon. When glucose was available, oxine increased the synthesis of trehalose without a comparable effect on glycogen synthesis. Cycloheximide increased trehalose synthesis to an even greater extent. The inhibition of glucose metabolism by oxine was concentration- and time-dependent. Oxine inhibition was reversible on transfer to nutrient solutions.
