Transition studies in flowering plants

The anthocyanin synthesis factor is present in yellow and red flowers in two variants (s1 & s2). The expression of these variants is 2-5 times higher in red flowers than in yellow flowers. In addition, an enhancer marked as TA_TC-box is present in red flowers in the regulatory sequence. Nevertheless, not in T30 & Y flowers indicates a connection between TF's expression and this section on the DNA. 
















 The bHLH79 factor is present in yellow and red flowers in eight different splicing variants. bHLH79 is assigned to the overall size of the flower. The expression of these variants is three times higher in yellow than in red flowers. In the enhancer section, the TA_TC-box sequence is present throughout in red flowers. Nevertheless, not in T & Y flowers indicates a correlation between TF's expression and this section on the DNA.
