| Zusammenfassung: | Nitric oxide (NO) is an essential regulatory molecule in several developmental and (patho) physiological processes. In this work, it is demonstrated that NO participates in the wound-healing response of potato leaves. The experimental approaches showed that the deposition of the cell-wall glucan callose was induced by the application of the NO donor sodium nitroprusside (SNP), and such induction was additive to the wound-induced callose production. Additionally, the expression of wound-related genes as phenylalanine ammonia-lyase (PAL) and extensin showed an accumulation of their transcript levels by SNP treatment. Moreover, the SNP-mediated increase of the PAL transcript level was additive to the induction mediated by wounding. These results indicate that increased levels of NO might potentiate the healing responses in plants leading to a rapid restoration of the damaged tissue |
