Abstract
Treatment of intact tobacco leaves with toxin-containing culture filtrates of Pseudomonas tabaci markedly reduced the ribonucleic acid content of the leaves. The decrease was counteracted by spraying the leaves with 10-4M kinetin. Simultaneously with the decrease in RNA, the ribonuclease activity of extracts from tissues treated with toxin increased. Experiments on the effect of kinetin on the ribonuclease activity of toxin-treated tissues gave no consistent results.Keywords
