The present invention provides several promoters isolated from Arabidopsis thaliana, which promoters are capable of driving and/or regulating the expression of an operably linked nucleic acid in a plant. The expression patterns of the promoters according to the present invention have been studied in Arabidopsis thaliana and some of the promoters displayed specific activity in particular cells, tissues or organs of the plant, while others displayed constitutive expression throughout substantially the whole plant. Some promoters showed weak expression, while others were strongly active.
