Fuente: WIPO "tomato" The present invention relates to synthetic enhancer elements that can be used to increase the expression of a gene of interest in any plant tissue. The disclosed synthetic enhancer elements can be used in a gene expression cassette comprising nucleic acid further comprising a promoter and a sequence to be expressed, wherein the sequence to be expressed has a transcription start site, and wherein the synthetic enhancer element is operably linked to the promoter and the sequence to be expressed. The present invention also relates to a modified plant or part thereof comprising a synthetic enhancer element, wherein the synthetic enhancer element is operably linked to an endogenous promoter in the modified plant or part thereof and an endogenous gene in the modified plant or part thereof, and wherein the synthetic enhancer element increases expression of a transcript or protein encoded by the endogenous gene.
