- Abstract
We investigated whether nitric oxide (NO) radical could induce phytoalexin production. Treatment of potato tuber tissues with 1-hydroxy-2-oxo-3,3-bis(2-aminoethyl)-1-triazene (NOC-18), an NO-releasing compound, induced the accumulation of the potato phytoalexin rishitin. This induction was inhibited by carboxy-2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (carboxy-PTIO), an NO-specific scavenger, or by Tiron, a radical scavenger, suggesting a phytoalexin inducing activity for NO.
