Generation of full-length cDNA clone and functional analysis of leader proteases of grapevine leafroll-associated virus-2

Creator:: Liu, Yu-Ping
Abstract:: Papain-like leader proteases are found in diverse families of human, animal, plant, and fungal positive-strand RNA viruses. In addition to autocatalytic processing, these proteases play a variety of roles in the virus life cycle. In particular, the leader protease (L-Pro) of a prototype member of the Closterovirus genus, Beet yellows...

Multiple functions of a proteinase in closterovirus life cycle

Creator:: Peng, Chih-Wen
Abstract:: More than half of the recognized genera of positive strand RNA viruses employ polyprotein processing as one of the strategies for their genome expression. Normally, this processing is mediated by virus-encoded proteinases that belong to the trypsin-like or papain-like family. In particular, papain-like, leader proteinases were found in diverse families...

The closterovirus-derived gene expression and RNA interference vectors as tools for research and plant biotechnology

Creator:: Dolja, Valerian V. and Koonin, Eugene V.
Abstract:: Important progress in understanding replication, interactions with host plants, and evolution of closteroviruses enabled engineering of several vectors for gene expression and virus-induced gene silencing. Due to the broad host range of closteroviruses, these vectors expanded vector applicability to include important woody plants such as citrus and grapevine. Furthermore, large...

Creator:: Krupovic, Mart, Dolja, Valerian V., and Koonin, Eugene V.
Abstract:: Plant viruses of the recently recognized family Amalgaviridae have monopartite double-stranded (ds) RNA genomes and encode two proteins: an RNA-dependent RNA polymerase (RdRp) and a putative capsid protein (CP). Whereas the RdRp of amalgaviruses has been found to be most closely related to the RdRps of dsRNA viruses of the...

Origins and evolution of viruses of eukaryotes: The ultimate modularity

Creator:: Koonin, Eugene V., Dolja, Valerian V., and Krupovic, Mart
Abstract:: Viruses and other selfish genetic elements are dominant entities in the biosphere, with respect to both physical abundance and genetic diversity. Various selfish elements parasitize on all cellular life forms. The relative abundances of different classes of viruses are dramatically different between prokaryotes and eukaryotes. In prokaryotes, the great majority...

Myosin-Powered Membrane Compartment Drives Cytoplasmic Streaming, Cell Expansion and Plant Development

Creator:: Peremyslov, Valera V., Cole, Rex A., Fowler, John E., and Dolja, Valerian V.
Abstract:: Using genetic approaches, particle image velocimetry and an inert tracer of cytoplasmic streaming, we have made a mechanistic connection between the motor proteins (myosins XI), cargo transported by these motors (distinct endomembrane compartment defined by membrane-anchored MyoB receptors) and the process of cytoplasmic streaming in plant cells. It is shown...

Plant viruses of the Amalgaviridae family evolved via recombination between viruses with double-stranded and negative-strand RNA genomes

Evaluation of grapevine red blotch virus epidemiology with reference to potential insect vectors

Creator:: Dalton, Daniel T.
Abstract:: Grapevine red blotch virus (GRBV), the causal agent of red blotch disease (RBD) in grapevine, Vitis vinifera L., is an emerging pathogen of significance to the wine grape industry of Oregon, USA. To address knowledge gaps of GRBV epidemiology, spread of GRBV was evaluated in Oregon vineyards over four years....

Comparative Genomics of Freshwater Bloom-Forming Cyanobacteria and Associated Organisms

Creator:: Driscoll, Connor B.
Abstract:: The advent of improved DNA sequencing technologies has allowed the analysis of various microbial communities. Bloom-forming freshwater cyanobacteria can produce toxins and taste-and-odor compounds that can negatively affect drinking water supplies. Here, I have employed second- and third-generation sequencing technologies to characterize bloom-forming freshwater cyanobacterial genomes and their associated heterotrophic...
