The invention relates to expression cassettes and vectors which contain constitutive promoters of plants and to the use of these expression cassettes or vectors for transgenic expression of nucleic acid sequences, preferably selection markers, in organisms, preferably in plants. The invention further relates to transgenic plants which have been transformed with the expression cassettes or vectors, to cultures, parts or propagation material derived from these plants, and to the use of these plants for the production of food and animal feedstuffs, seed, pharmaceuticals, or fine chemicals.
