Fig. 1From: Plant breeding at the speed of light: the power of CRISPR/Cas to generate directed genetic diversity at multiple sitesEditing of cis-regulatory elements for the generation of dosage effect alleles. In contrast to conventional editing of coding sequences, editing of cis-regulatory elements enables the fine-tuning towards optimal gene expression level. Red colour indicates repressive, green colour activating transcription factors. Red Triangles indicate CRISPR cleavage sites. Orange sections indicate CRISPR/Cas-induced mutationsBack to article page
