Altering Colors of Transgenic Flowers by RNAi-Mediated Method

1S K Padhi


Flower color is one of the most significant characteristics of ornamental plants. Several internal and external factors influence its growth and development. Consequently, the understanding and control of the color production process is an important theoretical basis and principle in developing and improving new ornamental plant color varieties. The essential cut-flower crop-carnation, genetically modified, color-altered varieties are now available commercially for almost a decade. The major cutflower plant carnations are now commercially available for almost ten years as genetically modified, color-altered varieties. The phenomenon of RNA interference (RNAi), which results in translational inhibition or transcriptional repression, has a role in sequence-specific gene regulation regulated by the introduction of dsRNA. Since, RNAi has been discovered and regulatory potential, the potential of RNAi to open a new view on agricultural improvement has become apparent.The biosynthetic pathway and pathway in which the genes are involved are so well characterized that the change in flower color can be affected by over-expressing heterologous genes and suppressing endogenous genes in transgenic plants.
