Garlic (Allium sativum L.) plants exhibiting mosaics, deformation, and yellow stripes symptoms were identified in Meerut City, Uttar Pradesh, India. To investigate the viruses in the garlic samples, the method of high-throughput sequencing (HTS) was used. Complete genome of the garlic virus E (GarV-E) isolate (NCBI accession No. MW925710) was retrieved. The virus complete genome comprises 8450 nucleotides (nts), excluding the poly (A) tail at the 3′ terminus, with 5′ and 3′ untranslated regions (UTRs) of 99 and 384 nts, respectively, and ORFs encoding replicase with a conserved motif for RNA-dependent RNA polymerase (RdRP), TGB1, TGB2, TGB3, serine-rich protein, coat protein, and nucleic acid binding protein (NABP). The sequence homology shared 83.49–90.40% and 87.48–92.87% with those of GarV-E isolates available in NCBI at the nucleotide and amino acid levels, respectively. Phylogenetic analysis showed a close relationship of this isolate from India (MW925710) with GarV-E isolate YH (AJ292230) from Zhejiang, China. The presence of GarV-E was also confirmed by RT-PCR. The present study is the first report of GarV-E in garlic cultivar Yamuna Safed-3 grown in northern India. However, further studies are needed to confirm its role in symptom development, nationwide distribution, genetic diversity, and potential yield loss to the garlic in India.

Vibrio alginolyticus is a ubiquitous Gram-negative bacterium which is normally distributed in the coastal and estuarine environments. It has been suggested to be an opportunistic pathogen to both marine animals and humans, Here, the completed genome sequence of V. alginolyticus ZJ-T was determined by Illumina high-throughput sequencing.

Worldwide, barley/cereal yellow dwarf viruses (YDVs) are the most widespread and damaging group of cereal viruses. In this study, we applied high-throughput sequencing technologies (HTS) to perform a virus survey on symptomatic plants from 47 cereal fields in Estonia. HTS allowed the assembly of complete genome sequences for 22 isolates of cereal yellow dwarf virus RPS, barley yellow dwarf virus GAV, barley yellow dwarf virus PAS (BYDV-PAS), barley yellow dwarf virus PAV (BYDV-PAV), and barley yellow dwarf virus OYV (BYDV-OYV). We also assembled a near-complete genome of the putative novel species BYDV-OYV from Swedish samples of meadow fescue. Previously, partial sequencing of the central part of the coat protein gene indicated that BYDV-OYV represented a putative new species closely related to BYDV-PAV-CN, which currently is recognized as a subtype of BYDV-PAV. The present study found that whereas the 3′gene block of BYDV-OYV shares the closest relationship with BYDV-PAV-CN, the 5′gene block of BYDV-OYV shows the closest relationships to that of BYDV-PAS. Recombination detection analysis revealed that BYDV-OYV is a parental virus for both. Analysis of complete genome sequence data indicates that both BYDV-OYV and BYDV-PAV-CN meet the species criteria of genus Luteovirus. The study discusses BYDV phylogeny, and through a systematic in silico analysis of published primers for YDV detection, the existing gaps in current diagnostic practices for detection of YDVs, proposing primer pairs based on the most recent genomic information for the detection of different BYDV species. Thanks to the rising number of sequences available in databases, continuous updating of diagnostic primers can improve test specificity, e.g., inclusivity and exclusivity at species levels. This is needed to properly survey the geographical and host distribution of the different species of the YDV complex and their prevalence in cereal/barley yellow dwarf disease epidemics.

Bacteriophages are the most abundant biological entities on the planet, playing crucial roles in the shaping of bacterial populations. Phages have smaller genomes than their bacterial hosts, yet there are currently fewer fully sequenced phage than bacterial genomes. We assessed the suitability of Illumina technology for high-throughput sequencing and subsequent assembly of phage genomes. In silico datasets reveal that 30× coverage is sufficient to correctly assemble the complete genome of ˜98.5% of known phages, with experimental data confirming that the majority of phage genomes can be assembled at 30× coverage. Furthermore, in silico data demonstrate it is possible to co-sequence multiple phages from different hosts, without introducing assembly errors.

Here, we report a novel phlebovirus-like virus sequence detected in a plasma sample from a febrile adult patient collected in the United Republic of Tanzania in 2014. A nearly complete RNA sequence was generated by high-throughput sequencing on a HiSeq 2500 instrument and further confirmed after repeating the analysis, starting from the initial sample.

ABSTRACT The complete genome sequences of 33 microviruses were determined from fecal samples collected from 14 Arizona-dwelling Gila monsters using high-throughput sequencing. These microviruses with genomes 4,383 to 6,782 nucleotides (nt) long were broadly distributed across the 14 samples.
