The intensity of flower colour, mainly determined by the amount of anthocyanin, is an important horticultural trait. To modulate flower colour intensity, post-transcriptional gene silencing (PTGS)-based technology has been widely used. The constraint of PTGS, however, is that it requires a high degree of conservation in the nucleotide sequences of the target and the silencer. Further, it is difficult to restrict PTGS to the desired tissue or organ due to its systemic spread. To overcome these… CONTINUE READING
