Polyamine oxidase from Avena sativa L. cv. Cristal seedlings was purified to homogeneity using a simple four-step purification protocol including an infiltration washing technique. The enzyme had a high affinity for spermidine and spermine (K(m) approximately 5.5 and 1.2 microM, respectively), and also oxidized norspermidine (K(m) approximately 64.0 microM). Natural and synthetic diamines, cycl...

The known extant plant pathogenic Ccrynehuc~terirm species were analyzed by polyacrylamide gel electrophoresis of their cellular proteins. The patterns of the protein bands of 13 species and a new corynebacterial wheat pathogen showed seven distinct groups. Five of these groups consisted of only one species each, one group contained four species, and the last group contained the new wheat patho...

TILIZING inherently resistant plants is the only known method for adequately U controlling the bacterial blight disease of cotton, which is caused by Xanthomonas malucrcearum (E. F . Sm.) Dowson. For this reason the development of resistant varieties has received considerable attention during the past decade. In 1939 SIMPSON and WEINDLING (1946) found a selection from Stoneville 2A which was re...
