Recent Advances in Function of Movement Protein of Barley Yellow Dwarf Virus and Its Application in Disease Resistance of Wheat
Barley yellow dwarf virus (BYDV) is transmitted by aphids and causes yellow dwarf disease in wheat, thus it is becoming a serious threat to triticeae crops production. Based on our studies in movement protein (MP) of BYDV, the latest knowledge on biochemical properties, biological function and disease resistance in wheat mediated by MP is reviewed in this paper. Up to now, it is known that BYDV-MP is capable of binding viral nucleotide acids and interacting with cellular membrane of host during BYDV systemic infection in plants, thus MP may be an important determinant for BYDV pathogenesis. This review will facilitate the deeper understanding on mechanism of interactions between BYDV and wheat plants and development of BYDV-tolerant wheat cultivars in the future.
