Abstract:
:The helicase-like 1a and polymerase-like 2a proteins of brome mosaic virus (BMV) are required for viral RNA replication in vivo, are present in membrane-bound viral RNA polymerase extracts, and share conservation with the many other members of the alphavirus-like superfamily. To better understand BMV RNA replication and BMV-host interactions, we used confocal microscopy and double-label immunofluorescence to determine and compare the sites of 1a, 2a, and nascent viral RNA accumulation in BMV-infected barley protoplasts. 1a and 2a showed nearly complete colocalization throughout infection, accumulating in defined cytoplasmic spots usually adjacent to or surrounding the nucleus. These spots grew throughout infection and by 16 h postinoculation often assumed a vesicle-like appearance. The BMV RNA replication complex incorporated 5-bromouridine 5'-triphosphate into RNA in vitro and in vivo, allowing immunofluorescent detection of nascent RNA. The cytoplasmic sites of BMV-specific RNA synthesis coincided with the sites of 1a and 2a accumulation, and at the resolution of confocal microscopy, all sites of 1a and 2a accumulation were sites of BMV RNA synthesis. Double-label immunofluorescence detection of selected subcellular markers and 1a or 2a showed that BMV replication complexes were tightly associated with markers for the endoplasmic reticulum but not the medial Golgi or later compartments of the cellular secretory pathway. Defining this association of BMV RNA replication complexes with endoplasmic reticulum markers should assist in identifying and characterizing host factors involved in BMV RNA replication.
