RNA-mediated signalling: a new information superhighway in plants?

摘要

The work discussed below features the discovery of a protein that can transport large RNA molecules in the plant phloem, thereby implying that there may be an 'RNA information superhighway' in plants. But a bit of background first. The use of transgenic organisms for studying over-expression and knock-out phenotypes has Revolutionized scientific experimentation over the past decade. There have been innumerable reports And review articles dealing with the use of antisense strategies to down-regulate specific gene Expression as well as to overexpress of particular cellular product by introducing the sense copy Of a gene.
