Garcia-RuizHernanBotanyPlantPathologyRolesProgramming.pdf

Creator:: Garcia-Ruiz, Hernan, Carbonell, Alberto, Hoyer, J. Steen, Fahlgren, Noah, Takeda, Atsushi, Giampetruzzi, Annalisa, Lowery, Nicholas, Carrington, James C., and et al.
Abstract:: In eukaryotes, ARGONAUTE proteins (AGOs) associate with microRNAs (miRNAs), short interfering RNAs (siRNAs), and other classes of small RNAs to regulate target RNA or target loci. Viral infection in plants induces a potent and highly specific antiviral RNA silencing response characterized by the formation of virus-derived siRNAs. Arabidopsis thaliana has...

Host-Specific Involvement of the HC Protein in the Long-Distance Movement of Potyviruses

Creator:: Sáenz, Pilar, Salvador, Beatriz, Simón-Mateo, Carmen, Kasschau, Kristin D., Carrington, James C., and García, Juan Antonio
Abstract:: Plum pox virus (PPV) is a member of the Potyvirus genus that, in nature, infects trees of the Prunus genus. Although PPV infects systemically several species of the Nicotiana genus, such as N. clevelandii and N. benthamiana, and replicates in the inoculated leaves of N. tabacum, it is unable to...

Roles and Programming of Arabidopsis ARGONAUTE Proteins during Turnip Mosaic Virus Infection

Functional Analysis of Three Arabidopsis ARGONAUTES Using Slicer-Defective Mutants

Creator:: Carbonell, Alberto, Fahlgren, Noah, Garcia-Ruiz, Hernan, Gilbert, Kerrigan B., Montgomery, Taiowa A., Nguyen, Tammy, Cuperus, Josh T., and Carrington, James C.
Abstract:: In RNA-directed silencing pathways, ternary complexes result from small RNA-guided ARGONAUTE (AGO) associating with target transcripts. Target transcripts are often silenced through direct cleavage (slicing), destabilization through slicer-independent turnover mechanisms, and translational repression. Here, wild-type and active-site defective forms of several Arabidopsis thaliana AGO proteins involved in posttranscriptional silencing were...

Evidence that the Potyvirus P1 Proteinase Functions in trans as an Accessory Factor for Genome Amplification

Creator:: Verchot, Jeanmarie and Carrington, James C.
Abstract:: The tobacco etch potyvirus (TEV) polyprotein is proteolytically processed by three viral proteinases (NIa, HC-Pro, and P1). While the NIa and HC-Pro proteinases each provide multiple functions essential for viral infectivity, the role of the P1 proteinase beyond its autoproteolytic activity is understood poorly. To determine if P1 is necessary...

Debilitation of Plant Potyvirus Infectivity by P1 Proteinase-Inactivating Mutations and Restoration by Second-Site Modifications

Creator:: Verchot, Jeanmarie and Carrington, James C.
Abstract:: Tobacco etch virus (TEV) encodes three proteinases that catalyze processing of the genome-encoded polyprotein. The P1 proteinase originates from the N terminus of the polyprotein and catalyzes proteolysis between itself and the helper component proteinase (HC-Pro). Mutations resulting in substitution of a single amino acid, small insertions, or deletions were...

Analysis of the VPg-Proteinase (NIa) Encoded by Tobacco Etch Potyvirus: Effects of Mutations on Subcellular Transport, Proteolytic Processing, and Genome Amplification

Creator:: Schadd, Mary C., Haldeman-Chahill, Ruth, Cronin, Stephen, and Carrington, James C.
Abstract:: A mutational analysis was conducted to investigate the functions of the tobacco etch potyvirus VPgproteinase (NIa) protein in vivo. The NIa N-terminal domain contains the VPg attachment site, whereas the C-terminal domain contains a picornavirus 3C-like proteinase. Cleavage at an internal site separating the two domains occurs in a subset...

Complementation of tobacco etch potyvirus mutants by active RNA polymerase expressed in transgenic cells

Creator:: Li, Xiao Hua and Carrington, James C.
Abstract:: A genetic complementation system was developed in which tobacco etch virus (TEV) polymerase (NIb)- expressing transgenic plants or protoplasts were inoculated with NIb-defective TEV mutants. A β-glucuronidase (GUS) reporter gene integrated into the genomes of parental and four mutant viruses was used to assay RNA amplification. Two mutants (termed VNN...

Abstract:: BACKGROUND: The wild grass Brachypodium distachyon has emerged as a model system for temperate grasses and biofuel plants. However, the global analysis of miRNAs, molecules known to be key for eukaryotic gene regulation, has been limited in B. distachyon to studies examining a few samples or that rely on computational...
