Regulation of Eukaryotic Initiation Factor 4E and its Isoform: Implications for Antiviral Strategy in Plants
首发时间:2006-07-17
摘要:In recent years, biotechnology has permitted regulation of the expression of endogenous plant genes to improve agronomically important traits. Genetic modification of crops has benefited from emerging knowledge of new genes, especially genes that exhibit novel functions, one of which is eukaryotic initiation factor 4E (eIF4E). eIF4E is one of the most important translation initiation factors involved in eukaryotic initiation. Recent research has demonstrated that virus resistance mediated by eIF4E and its isoform eIF(iso)4E occurs in several plant–virus interactions, thus indicating a potential new role for eIF4E/eIF(iso)4E in resistance strategies against plant viruses. In this review, we briefly describe eIF4E activity in plant translation, its potential role, and functions of the eIF4E subfamily in plant–virus interactions. Other initiation factors such as eIF4G could also play a role in plant resistance against viruses. Finally, the potential for developing eIF4E-mediated resistanc

Regulation of Eukaryotic Initiation Factor 4E and its Isoform: Implications for Antiviral Strategy in Plants
Abstract:In recent years, biotechnology has permitted regulation of the expression of endogenous plant genes to improve agronomically important traits. Genetic modification of crops has benefited from emerging knowledge of new genes, especially genes that exhibit novel functions, one of which is eukaryotic initiation factor 4E (eIF4E). eIF4E is one of the most important translation initiation factors involved in eukaryotic initiation. Recent research has demonstrated that virus resistance mediated by eIF4E and its isoform eIF(iso)4E occurs in several plant–virus interactions, thus indicating a potential new role for eIF4E/eIF(iso)4E in resistance strategies against plant viruses. In this review, we briefly describe eIF4E activity in plant translation, its potential role, and functions of the eIF4E subfamily in plant–virus interactions. Other initiation factors such as eIF4G could also play a role in plant resistance against viruses. Finally, the potential for developing eIF4E-mediated resistance to plant viruses in the future is discussed. Future research should focus on elucidation of the resistance mechanism and spectrum mediated by eIF4E. Knowledge of a particular plant–virus interaction will help to deepen our understanding of eIF4E and other eukaryotic initiation factors, and their involvement in virus disease control.
