A method of modifying a gene encoding or processed into a non-coding RNA molecule having no RNA silencing activity in a plant cell is disclosed. The method comprising introducing into the plant cell a DNA editing agent conferring a silencing specificity of the non-coding RNA molecule towards a target RNA of interest. A method of modifying a gene encoding or processed into a RNA silencing molecule in a plant cell is also disclosed. The method comprising introducing into the plant cell a DNA editing agent which redirects the silencing specificity of the non-coding RNA molecule towards a target RNA of interest. Plant cells, plant seeds, plants, and methods of generating plants are also disclosed.
