Luteovirus cap-independent translation element (BTE)

The Luteovirus cap-independent translation element (BTE) is an RNA element found in the 3' UTR of barley yellow dwarf virus (BYDV), bean leafroll virus and soybean dwarf virus. This element mediates translation of genomic RNA and subgenomic RNA1 (sgRNA1).

In terms of its secondary structure the BTE contains four stem-loops called SL-I to SL-IV.
