Figure 1From: Morphological and molecular characterization of a spontaneously tuberizing potato mutant: an insight into the regulatory mechanisms of tuber inductionScheme of the T-DNA insertion into non-coding region between 25S and 18S rDNA genes in ST mutant. TX, modified CaMV 35S promoter for gene activation; IGS, intergenic spacer; TTR, transcription terminator region; NTS, non-transcribed spacer; ETS, external transcribed spacer (the scheme of the intergenic spacer according to [46]).Back to article page
