Abstract

Plant virus was a kind of organism lived depending on infecting viable host cell and propagated their posterity by replicating its hereditary nucleotide, transcripting into protein, assembling protein and nucleotide into virion (Ortín and Parra, 2006; Sanfaçon, 2005). Viral infection usually induces remodeling of host cell, especially endoplasmic reticulum (ER) for generating membrane packed viral factory. During the infection of Bymovirus, a kind of membranous body (MB) was generated in host cells, which is thought as an ER aggregate. In present study we performed a study on Wheat yellow mosaic virus (WYMV) induced MB by several transmission electron microscopy (TEM) based methods, including cytological observation, component analysis by immuno-gold labeling and structural analysis by electron tomography (ET). WYMV infection induced at least two morphologies of MB, including the lamella dominated morphology (lamella-MB) looked like sprawling cirrus, and the tubule dominated morphology (tubule-MB) looked like latticed network. MB was verified composing of ER as revealed by immuno-gold labeling by antibody against endoplasmic reticulum (ER) retention signal as well as by detailed observation of MB construction modules as double ...Continue Reading
