Alternative Translation Strategies in Plant Viruses
نویسندگان
چکیده
Plant viruses have evolved several unconventional translational strategies that allow efficient expression of more than one protein from their compact, multifunctional RNAs, as well as regulation of polycistronic translation in the infected plant cell. Here, we review recent advances in our understanding of these unconventional mechanisms, which include leaky scanning, ribosome shunting, internal initiation, reinitiation, stop codon suppression and frameshifting, and compare their characteristics with related phenomena in other systems. _____________________________________________________________________________________________________________

Plant Translation Factors and Virus Resistance
Plant viruses recruit cellular translation factors not only to translate their viral RNAs but also to regulate their replication and potentiate their local and systemic movement. Because of the virus dependence on cellular translation factors, it is perhaps not surprising that many natural plant recessive resistance genes have been mapped to mutations of translation initiation factors eIF4E and...
متن کاملNon-canonical Translation in Plant RNA Viruses
Viral protein synthesis is completely dependent upon the host cell's translational machinery. Canonical translation of host mRNAs depends on structural elements such as the 5' cap structure and/or the 3' poly(A) tail of the mRNAs. Although many viral mRNAs are devoid of one or both of these structures, they can still translate efficiently using non-canonical mechanisms. Here, we review the tool...
متن کاملTranslational control in positive strand RNA plant viruses.
The great variety of genome organizations means that most plant positive strand viral RNAs differ from the standard 5'-cap/3'-poly(A) structure of eukaryotic mRNAs. The cap and poly(A) tail recruit initiation factors that support the formation of a closed loop mRNA conformation, the state in which translation initiation is most efficient. We review the diverse array of cis-acting sequences pres...
متن کاملTranslational control in plant antiviral immunity
Due to the limited coding capacity of viral genomes, plant viruses depend extensively on the host cell machinery to support the viral life cycle and, thereby, interact with a large number of host proteins during infection. Within this context, as plant viruses do not harbor translation-required components, they have developed several strategies to subvert the host protein synthesis machinery to...
متن کاملCap-independent translation of plant viral RNAs.
The RNAs of many plant viruses lack a 5' cap and must be translated by a cap-independent mechanism. Here, we discuss the remarkably diverse cap-independent translation elements that have been identified in members of the Potyviridae, Luteoviridae, and Tombusviridae families, and genus Tobamovirus. Many other plant viruses have uncapped RNAs but their translation control elements are uncharacter...
