Nitric oxide action in the digestive fluid of Nepenthes × ventrata is linked to the modulation of ROS level.

Nepenthes are carnivorous plants with photoactive leaves converted into jug-shaped containers filled with the digestive fluid. The digestion requires various enzymes and reactive oxygen species (ROS) that facilitate proteolysis. Reactive nitrogen species are present in the digestive fluid of Nepenthes × ventrata, and the increased nitric oxide (NO) formation is associated with protein degradation.

Is the Phytotoxic Effect of Digestive Fluid of on Tomato Related to Reactive Oxygen Species?

The digestive fluid of pitcher plants is a rich source of enzymes and secondary metabolites, but its impact on higher plant growth and development remains unknown. The aim of the study was to determine the phytotoxicity of the digestive fluid of the pitcher plant () on the germination of tomato ( L.) seeds, elongation growth and cell viability of roots of tomato seedlings.
