Abstract:
RNA silencing (also known as gene silencing) is an evolutionary conserved mechanism that is involved in regulating gene expression, suppressing mobile elements, and defensing virus infection. RNA silencing is triggered by double-stranded RNA via Dicer or Dicer-like riboendonucleases. DsRNAs are also the replication intermediates of all RNA viruses; as a result, plant RNA viruses are ideal candidates to induce RNA silencing. A large body of plant viruses have been modified into vectors for RNA silencing in varied plant species. Here, we described a simple, time-saving, and operable system for gene function and genetic breeding study of potato and Nicotiana benthamiana using a potato mop-top (MPTV)-based vector.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...
RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
