The capsid protein of citrus leprosis virus C shows a nuclear distribution and interacts with the nucleolar fibrillarin protein.

ABSTRACT: Brevipalpus-transmitted viruses (BTVs) have a significant negative economic impact on the citrus industry in Central and South America. Until now, only a few studies have explored the intracellular distribution and interaction of BTVs-encoded proteins with host factors, particularly for cileviruses, the main BTV responsible for the Citrus Leprosis (CL) disease. This study describes the nuclear localization of citrus leprosis virus C (CiLV-C) capsid protein (p29) and its interaction with the fibrillarin (Fib2) within the nucleolar compartment and cell cytoplasm. Our results, obtained by computer predictions and laser scanning confocal microscopy analyses, including colocalization and bimolecular fluorescence complementation (BiFC) approaches, revealed that a fraction of the p29 is localized
