Main conclusion A novel Torenia phenotype having separate petals was obtained by the combination of NF-YA6 - VP16 with a floral organ-specific promoter. Genetic engineering techniques helped in obtaining novel flower colors and shapes, in particular, by introducing functionally modified transcriptio...
