Abstract Close correlations between [0III] emission features and radio components have been found in a project of high resolution long-slit spectroscopy of Seyfert galaxies with linear radio structures in their nuclei. Substructures in the [0III] line profiles can, in several cases, be associated with individual radio components, within the Narrow Line Region. The observed properties of these [0III] features suggest that gas behind the bow shock of an outmoving radio plasmon has cooled and then is photoionized by the central continuum source. About half of the objects studied possess an Extended Narrow Line Region which could be interstellar gas, photoionized by energetic radiation from the nucleus, beamed along the axis of the (jet-like) radio structure.
