Why introduction of an extra copy of a gene related to pigmentation causes RNA interference in Petunia?
RNAi became famous after Fire and Mello experiment in C.elegans; however, it had been observed before. In the 80's, Jorgensen was trying to increase pigmentation of Petunia flowers by introducing ...
For example, consider a gene X which has an intron which encodes a miRNA that downregulates expression of another gene Y. When the gene X is translated, this miRNA will appear as a byproduct of ...
