A High Resolution Short Interfering RNA (siRNA) Detection Method from Virus-infected Plants
Authors:  Vinay Panwar and Guus Bakkeren, date: 10/20/2013, view: 11866, Q&A: 0
Plant viruses are strong inducers as well as targets of RNA silencing. In plants RNA silencing acts as a natural defense mechanism against viral infection and is associated with accumulation of virus-specific small interfering RNAs (siRNAs). The ...
