Towards precision quantification of contamination in metagenomic sequencing experiments

open access: yesMicrobiome, 2019
Metagenomic next-generation sequencing (mNGS) experiments involving small amounts of nucleic acid input are highly susceptible to erroneous conclusions resulting from unintentional sequencing of occult contaminants, especially those derived from ...

Completely mitochondrial genome of Neolissochilus heterostomus

open access: yesMitochondrial DNA. Part B. Resources, 2021
In this study, we determined the complete mitochondrial genome of Neolissochilus heterostomus. The genome is 16,585 bp in length, including 2 ribosomal RNA genes, 13 proteins-coding genes, 22 transfer RNA genes, and two non-coding control regions ...

High-Throughput DNA Analysis Platform Based on an Optofluidic Ring Resonator Laser

open access: yesApplied Sciences, 2022
We demonstrate an optofluidic laser using DNA microdroplets, an intercalating dye, and a glass capillary ring resonator. Only the target DNA emits the laser signal, while the non-target DNA, including those with single-base mismatches, exhibits zero ...

Mesoscopic Model for Free Energy Landscape Analysis of DNA sequences [PDF]

open access: yesPhysical Review E 86, 021908 (2012), 2012
A mesoscopic model which allows us to identify and quantify the strength of binding sites in DNA sequences is proposed. The model is based on the Peyrard-Bishop-Dauxois model for the DNA chain coupled to a Brownian particle which explores the sequence interacting more importantly with open base pairs of the DNA chain.

Bending short DNAs as transversely isotropic rings in series [PDF]

open access: yes, 2023
Despite the significance of the high flexibility exhibited by short DNAs, there remains an incomplete understanding of their anomalous persistence length. In this study, we propose a novel approach wherein each fundamental characteristic of gene sequences within short DNAs is modeled as a transversely isotropic ring.

A Novel Method for Alignment-free DNA Sequence Similarity Analysis Based on the Characterization of Complex Networks

open access: yesEvolutionary Bioinformatics, 2016
Determination of sequence similarity is one of the major steps in computational phylogenetic studies. One of the major tasks of computational biologists is to develop novel mathematical descriptors for similarity analysis.

On Coding for an Abstracted Nanopore Channel for DNA Storage [PDF]

open access: yesarXiv, 2021
In the emerging field of DNA storage, data is encoded as DNA sequences and stored. The data is read out again by sequencing the stored DNA. Nanopore sequencing is a new sequencing technology that has many advantages over other methods; in particular, it is cheap, portable, and can support longer reads.

Detection and characterization of tomato leaf curl New Delhi virus association with mosaic disease of ivy gourd (Coccinia grandis (L.) Voigt) in North India [PDF]

open access: yesArchives of Biological Sciences, 2018
Sixteen ivy gourd (Coccinia grandis (L.) Voigt) plant samples showing severe mosaic symptoms were collected from New Delhi and Varanasi (Uttar Pradesh) in India. Begomovirus infection was confirmed by PCR using begomovirusspecific primers.

Reclassification of Enterobacter sp. FY-07 as Kosakonia oryzendophytica FY-07 and Its Potential to Promote Plant Growth

open access: yesMicroorganisms, 2022
Precise classification of bacteria facilitates prediction of their ecological niche. The genus Enterobacter includes pathogens of plants and animals but also beneficial bacteria that may require reclassification.

Sequence analysis of four caprine mitochondria DNA lineages

open access: yesItalian Journal of Animal Science, 2012
The complete mitochondrial DNA (mtDNA) (16640bp in length) was sequenced from four Chinese goat lineages representing the four major mtDNA haplogroups in goats. A total of 124 single nucleotide polymorphisms (SNPs) were found in encoding regions, and the
