Plant virology and experimentations

This trend has been observed Plant virology and experimentations crop plants but also, to a very large extent, in wild plant species through the use of NGS in metagenomic approaches Stobbe and Roossinck, ; Roossinck, ; Roossinck et al. Molecular virology was also instrumental in the discovery, by Theodor O.

Similarly, Ji et al. Podleckis, personal communication ; M. In addition, NGS librarary prepation methods with minimal bias should be used in order to obtain accurate and easy to interpret data Van Dijk et al.

Next-generation sequencing of vsRNAs or vd-sRNAs has also been used in various studies on viruses or viroids, which include, but are not limited to, their characterization, profiling, distribution, accumulation, biogenesis, as well as their use in extending the known pathogen host range, and in virus strain differentiation, systemic movement, virus or viroid-host interaction, viroid evolution, and pathogenesis, mutation, mRNA targeting, and others Tables 1 and 2.

Mice inoculated with ATCV 1, however, developed memory loss and other symptoms indicating a general decrease performance in several cognitive domains. Authors of published original research with the highest impact, as judged democratically by the readers, will be invited by the Chief Editor to write Plant virology and experimentations Frontiers Focused Review - a tier-climbing article.

Plant Virology

NGS in Plant Virology Next-generation sequencing, combined with informatics for de novo discovery and assembly of plant virus or viroid genome reads, has been used sincefirst in discovering novel DNA and RNA viruses Adams et al.

The Cas proteins, such as Cas9, are RNA-directed endonucleases able to recognize and cleave nucleic acids on the basis of sequence complementarities Brouns et al.

Moreover, it was used in the same year for sequencing viroid-derived small RNAs vd-sRNAs to study the role of RNA silencing in plant—viroid interactions, particularly for nuclear-replicating viroids Navarro et al. The very large variability among plant viruses and among viroids complicates their discovery, detection, quarantine, and certification as well as their etiological studies by standard methods, which could be overcome or made easier by next-generation sequencing NGS technology.

Thus, NGS has the potential to be utilized in plant quarantine and certification programs standard assays in North America and Europe in the near future as, when compared with routine conventional assays, it could reduce significantly the number of non-detected viruses and viroids.

AH prepared the final version of the manuscript and all authors approved it. During the last few years, the CRISPR-Cas based systems have become the method of choice for genome editing by introducing or correcting genetic mutations in a wide variety of biological contexts: NGS and genome engineering.

It has been 10 years since the publication of the fourth edition, during which there has been an explosion of conceptual and factual advances.

Viroids are also accurately and easily detected and identified by NGS Table 3. Current strategies for controlling geminiviruses vary from conventional breeding of resistant cultivars and insect vectors control to molecular methods based on transgenic plants expressing mutated viral proteins, RNA-mediated interference and others Pilartz and Jeske, ; Vanderschuren et al.

All these strategies have met so far with marginal success. NGS has been used in a number of studies in plant virology including, but not limited to, discovery of novel viruses and viroids as well as detection and identification of those pathogens already known, analysis of genome diversity and evolution, and study of pathogen epidemiology.

The DNA viruses targeted include tomato yellow leaf curl virus and merremia mosaic virus begomovirus ; beet curly top virus and beet severe curly top virus curtovirus ; and bean yellow dwarf virus mastrevirus.

Using NGS in a quarantine program, a novel virus in imported sugarcane was discovered that previously escaped detection by standard detection methods. On the other hand, DNA viruses that infect the green alga Phaeodactylum tricornutum have been associated with vaginitis Stepanova et al.

They replicate in plant nuclei through dsDNA intermediates that also serve as templates for transcription Pilartz and Jeske, Revamped art, along with fully updated references and increased focus on molecular biology, transgenic resistance, aphid transmission, and new, cutting-edge topics, bring the volume up to date and maintain its value as an essential reference for researchers and students in the field.Plant Virology by Roger Hull It has been ten years since the publication of the third edition of this seminal text on plant virology, during which there has been an explosion of conceptual and factual $ Committed to covering all areas within virology research, Virology Journal accepts manuscripts from basic, clinical and translational research on the viruses of humans, animals, plants and microbes.
