Genetically Engineered Wheat for Barley Yellow Dwarf Virus Resistance

摘要

Barley yellow dwarf virus-PAV (BYDV-PAV) causes substantial losses (Lister and Ranieri, 1995) throughout the world in wheat (17%), barley (15%), and oats (25%). Similar to conventional breeding methods, genetic engineering is a potentially important tool to develop virus resistance. In this case, pathogen-derived resistance is the strategy commonly used (Lomonossoff, 1995). This strategy involves using as a gene, a part of the virus genome in order to disrupt infection by the invading virus, according to the process observed in cross-protection.
