BIOCHEMICAL STUDIES ON THE RICE BLAST DISEASE (PART 10) BIOCHEMICAL CLASSIFICATION OF PIRICULARIA ORYZAE (NO. 3)
Abstract
Experimenting with the 45 stock-cultures of P.o.c. on the extent of their consumption of various nitrogen sources, amino acid in particular, the following results were obtained: (1) The following substances are excellent nitrogen-sources -- asparagine, aspartic acid, arginine, alanine, proline, serine, glycine, histidine, glutamic acid and NaNO3, while such substances as oxiproline, cystine, phenylalanine, tryptophane and NaNO2 provide a poor source. (2) The four stock-cultures No 11 F8 hetero, No 188 hetero, A 36 and 5539 do not show nitric acid reducibility, while the remaining 41 stocks show the sign of nitric acid reducibility. (3) The 45 stock-cultures of P.o.c. were classified into 10 families in terms of nitric acid reducibility and the use of NaNO2 and tryptophane in its propagation.
