| Abstract: | RNA mainly existed as the single-stranded molecule in organisms is the genetic information carrier, and plays an important role in the transfer of genetic information. In addition, RNA as a nucleic acid enzyme regulates the cellular metabolism. There are three types of RNA molecules that could travel in plants systemically, including the virus RNA, mobile signals of RNA silencing and endogenous RNA. The current advances of systematic transport of RNA and their functions in plant gene expression are reviewed. |
