Summary
We sequenced the Grapevine leafroll-associated virus 13 (GLRaV-13) genome from a California Vitis vinifera isolate. This finding enhances understanding of ampelovirus genetic diversity in grapevines.
Area of Science:
- Plant virology
- Genomics
- Agricultural science
Background:
- Grapevine leafroll disease is a major threat to viticulture worldwide.
- Grapevine leafroll-associated virus 13 (GLRaV-13) is an ampelovirus implicated in this disease.
- Understanding viral genetic diversity is crucial for disease management.
Purpose of the Study:
- To report the complete genome sequence of a novel GLRaV-13 isolate.
- To analyze the genetic relatedness of this isolate to other known GLRaV-13 strains.
- To contribute to the knowledge of ampelovirus diversity in grapevine.
Main Methods:
- Isolate collection from Vitis vinifera in California.
- Whole-genome sequencing of the Grapevine leafroll-associated virus 13 (GLRaV-13) isolate.
- Bioinformatic analysis of nucleotide sequence identity.
Main Results:
- The coding-complete genome sequence of GLRaV-13 isolate CA8881 was determined.
- The CA8881 isolate showed over 95% nucleotide identity with previously reported GLRaV-13 isolates.
- This sequence data provides insights into ampelovirus genetic variation.
Conclusions:
- The genome sequence of GLRaV-13 isolate CA8881 expands the genomic resources for grapevine viruses.
- This study enhances the understanding of genetic diversity within the Ampelovirus genus.
- Further research on viral genetic diversity can inform grapevine disease control strategies.

01:57Sanger Sequencing
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
01:29Viruses with RNA Genomes
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...
01:26DNA Bacteriophages
Bacteriophages, or phages, are viruses that specifically infect bacteria, utilizing their genetic material to hijack host cellular machinery for replication. DNA bacteriophages employ single-stranded DNA (ssDNA) or double-stranded DNA (dsDNA) genomes. These phages exhibit diverse replication strategies and host interactions, influencing their ecological roles and applications in biotechnology and medicine.ssDNA BacteriophagesssDNA phages, with their small genomes, utilize unique strategies to...
02:35RACE - Rapid Amplification of cDNA Ends
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific primer.

02:02Genomics
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
01:23Bacteriophages of the Human Virome
Bacteriophages are found throughout the human body. They may even outnumber eukaryotic viruses, forming an important and dynamic component of the human virome. Indeed, phages represent the most abundant viral entities, with densities in the gut reaching up to 10⁹ particles per gram of fecal matter, and many belonging to orders such as Caudovirales and Microviridae, while a substantial proportion remains unclassified as viral “dark matter.”Lysogeny and Genetic ExchangeIn the gut, bacteriophages...
