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...

Identification of Myosin XI Receptors in Arabidopsis Defines a Distinct Class of Transport Vesicles

Creator:: Peremyslov, Valera V., Morgun, Eva A., Kurth, Elizabeth G., Makarova, Kira S., Koonin, Eugene V., and Dolja, Valerian V.
Abstract:: To characterize the mechanism through which myosin XI-K attaches to its principal endomembrane cargo, a yeast two-hybrid library of Arabidopsis thaliana cDNAs was screened using the myosin cargo binding domain as bait. This screen identified two previously uncharacterized transmembrane proteins (hereinafter myosin binding proteins or MyoB1/2) that share a myosin...

Virus-Derived Gene Expression and RNA Interference Vector for Grapevine

Creator:: Kurth, Elizabeth G., Peremyslov, Valera V., Prokhnevsky, Alexey I., Kasschau, Kristin D., Miller, Marilyn, Carrington, James C., and Dolja, Valerian V.
Abstract:: The improvement of the agricultural and wine-making qualities of the grapevine (Vitis vinifera) is hampered by adherence to traditional varieties, the recalcitrance of this plant to genetic modifications, and public resistance to genetically modified organism (GMO) technologies. To address these challenges, we developed an RNA virus-based vector for the introduction...

Expression, Splicing, and Evolution of the Myosin Gene Family in Plants

Creator:: Peremyslov, Valera V., Mockler, Todd C., Filichkin, Sergei A., Fox, Samuel E., Jaiswal, Pankaj, Makarova, Kira S., Koonin, Eugene V., and Dolja, Valerian V.
Abstract:: Plants possess two myosin classes, VIII and XI. The myosins XI are implicated in organelle transport, filamentous actin organization, and cell and plant growth. Due to the large size of myosin gene families, knowledge of these molecular motors remains patchy. Using deep transcriptome sequencing and bioinformatics, we systematically investigated myosin...

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...

Genetic requirements for the assembly and cell-to-cell movement of the beet yellows virus

Creator:: Alzhanova, Dina
Abstract:: Beet yellows virus (BYV) is a filamentous, positive-strand RNA virus that belongs to the family Closteroviridae. BYV particles encapsidate a 15.5 kb RNA and posses complex polar architecture. A long virion body is formed by the major capsid protein(CP), whereas the minor capsid protein (CPm) assembles a short tail that...

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...

Genomic and biological analysis of Grapevine leafroll-associated virus 7 reveals a possible new genus within the family Closteroviridae

Creator:: Al Rwahnih, Maher, Doljab, Valerian V., Dauberta, Steve, Koonin, Eugene V., and Rowhani, Adib
Abstract:: Deep sequencing analysis of an asymptomatic grapevine revealed a virome containing five RNA viruses and a viroid. Of these, Grapevine leafroll-associated virus 7 (GLRaV-7), an unassigned closterovirus, was by far the most prominently represented sequence in the analysis. Graft-inoculation of the infection to another grape variety confirmed the lack of...
