“…Asparagine, 011 the other hand, promoted the production of typical conidia. These results are similar to those of Spoerl, Saracheck, and Smith ( 7 ) , who observed that glycine did not inhibit n~itosis, but inhibited cellular division in LTsfilago sphaeroge7za, whereas asparagine stimulated cellular division.…”

Conidia of Iiabatiella caz~livora (Icirch.) Karak. were observed to develop into various forms when cultured on different media. Conidial forms appeared t o fall into four main categories with each form capable of prod~rcing typical conidia. These included (a) sickle-shaped, unicellular, hyaline conidia containing from 1-8 nuclei; (b) cylindrical to clavate, one-t o two-celled hyaline conidia with 5-15 nuclei per cell; (c) multicellular, light t o dark green conidia containing as many as 25 nuclei in the terminal cells; (d) cylindrical, two-to five-celled, dark brown, heavy-walled conidia containing 2-4 nuclei per cell. The above conidial forms have been observed in infected plant material.IManuscript received October 13, 1961. Contribution No. 113 fro111 the

“…Methionine, another of the sulfurcontaining amino acids, also has been implicated in the division mechanism. Spoerl et al found that this amino acid, as well as several other metabolites, occasioned the development of short, rod-like cells of the fungus Ustilago sphaerogena, instead of the long, mycelial-like form (25). Conversely, the growth of Chlorella vulgaris can be uncoupled from division by selenomethionine [CH3-Se-CH,CH2CH-(NH2) COOH], a structural analogue known to competitively antagonize methionine (23).…”

Spoerl, Edward, and J. L. Pullman. (U. S. Army Med. Res. Lab., Fort Knox, Ky.) Effects of purines, pyrimidines and related compounds upon cell form in Ustilago sphaerogena. Amer. Jour. Bot. 46(9): 651–656. 1959.—Nucleotide, nucleoside and base constituents of ribosenucleic acid, singly and in combination, were used as nitrogen sources for U. sphaerogena and examined for their effects upon cell form. Combinations of nucleotides, and adenine, produced long cells, i.e., interfered with cell division. A variety of analogues, especially of purine types, was examined for their effects upon cell form. Although adenine produced long cells, a hydroxy group substituted at the 6 position of the purine ring produced short cells. Sulfhydryl, furfurylamino and methyl groups substituted at the 6 position produced long cells. Additional groups and combinations of these groups also were examined. Neither hydroxypurines nor methionine or norleucine, which normally promote short‐cell formation, effectively antagonized the adenine effect, although norleucine tended to counteract a dimercaptopurine effect.
