Yellow Dwarf Viruses of Cereals: Taxonomy and Molecular Mechanisms.
Yellow dwarf viruses are the most economically important and widespread viruses of cereal crops. Although they share common biological properties such as phloem limitation and obligate aphid transmission, the replication machinery and associated cis-acting signals of these viruses fall into two unrelated taxa represented by Barley yellow dwarf virus and Cereal yellow dwarf virus. Here, we explain the reclassification of these viruses based on their very different genomes. We also provide an overview of viral protein functions and their interactions with the host and vector, replication mechanisms of viral and satellite RNAs, and the complex gene expression strategies. Throughout, we point out key unanswered questions in virus evolution, structural biology, and genome function and replication that, when answered, may ultimately provide new tools for virus management. Expected final online publication date for the Annual Review of Phytopathology, Volume 60 is August 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
期刊介绍:
The Annual Review of Phytopathology, established in 1963, covers major advancements in plant pathology, including plant disease diagnosis, pathogens, host-pathogen Interactions, epidemiology and ecology, breeding for resistance and plant disease management, and includes a special section on the development of concepts. The journal is now open access through Annual Reviews' Subscribe to Open program, with articles published under a CC BY license.
