Target mimicry provides a new mechanism for regulation of microRNA activity
MicroRNAs (miRNA) regulate key aspects of development and physiology in animals and plants. These regulatory RNAs act as guides of effector complexes to recognize specific mRNA sequences based onExpand

Highlights and prospects of potyvirus molecular biology.
The potyvirus group [named after its type member, potato virus Y (PVY)] is the largest of the 34 plant virus groups and families currently recognized (Ward & Shukla, 1991). It contains at least 180Expand

Molecular biology of potyviruses.
Potyvirus is the largest genus of plant viruses causing significant losses in a wide range of crops. Potyviruses are aphid transmitted in a nonpersistent manner and some of them are also seedExpand

GRAB proteins, novel members of the NAC domain family, isolated by their interaction with a geminivirus protein
Geminiviruses encode a few proteins and depend on cellular factors to complete their replicative cycle. As a way to understand geminivirus-host interactions, we have searched for cellular proteinsExpand

Recombination and gene duplication in the evolutionary diversification of P1 proteins in the family Potyviridae.
Genome structure and sequence are notably conserved between members of the family Potyviridae. However, some genomic regions of these viruses, such as that encoding the P1 protein, show strikinglyExpand

RNA Silencing Suppression by a Second Copy of the P1 Serine Protease of Cucumber Vein Yellowing Ipomovirus, a Member of the Family Potyviridae That Lacks the Cysteine Protease HCPro
ABSTRACT The P1 protein of viruses of the family Potyviridae is a serine proteinase, which is highly variable in length and sequence, and its role in the virus infection cycle is not clear. One ofExpand

Plum pox virus and sharka: a model potyvirus and a major disease.
TAXONOMIC RELATIONSHIPS Plum pox virus (PPV) is a member of the genus Potyvirus in the family Potyviridae. PPV diversity is structured into at least eight monophyletic strains. GEOGRAPHICALExpand

Construction of a stable and highly infectious intron-containing cDNA clone of plum pox potyvirus and its use to infect plants by particle bombardment.
An infectious plum pox potyvirus cDNA clone was constructed placing a copy of the full-length sequence of the virus genome between an enhanced cauliflower mosaic virus 35S promoter and a nopalineExpand

Multiple resistance traits control Plum pox virus infection in Arabidopsis thaliana.
Twelve Arabidopsis accessions were challenged with Plum pox potyvirus (PPV) isolates representative of the four PPV strains. Each accession supported local and systemic infection by at least some ofExpand

Identification of a plum pox virus CI-interacting protein from chloroplast that has a negative effect in virus infection.
The cylindrical inclusion (CI) protein of potyviruses is involved in virus replication and cell-to-cell movement. These two processes should rely on multiple plant-virus interactions; however, littleExpand
