Fuente: WIPO "tomato" Crop and other plants with increasing the expression of the transcription factor ETTIN are disclosed. The expression of ETTIN in a plant is increased by reducing the transcription of an Upstream OPEN READING FRAME (uORF) which is located upstream of the ETTIN coding sequence. Reduced expression of the ETTIN gene confers a dwarf phenotype in the plant. The plant in which the ETTIN uORF is targeted may be a rootstock of a crop plant. The rootstock may be grafted to a scion of a crop plant and the scion exhibits a dwarf phenotype. The present disclosure provides a means of creating mutations in uORFs DNA repressor elements for the purpose of generating new dwarf crop varieties.
