Research Progress of Proteins Associated with Per os Infectivity of the Occlusion-derived Virus

Abstract

Abstract: The study of baculovirus proteins associated with per os infectivity is of great importance not only for viral biology but also for the fact that these proteins expose vulnerabilities in the insect immune system and this knowledge is also fundamental for the development of new strategies for insect control. Recent researches show that the proteins associated with per os infectivity of the occlusion-derived virus（ODV）include P74, PIF1, PIF2, PIF3, PIF4, PIF5（ODV-E56）, PIF6, ODV-E66, VP91, Ac108, ORF 145 and ORF 150. This paper reviewed recent research achievements about the structure and function of the proteins and analyzed the molecular biology characteristics of these proteins.

Key words: Baculovirus , Occlusion-derived virus , Per os infectivity factors , Molecular characteristics.
