虽然由很多厉害的算法努力通过重叠序列(overlapping sequences)连接短的读段(reads),但由于基因组的绝对长度和复杂性使得很难生成完整序列,经常会导致许多缺失部分和错误。这推动了许多long-read sequencing策略的发展。两个最常用的商用技术就是: Pacific Biosciences’ Single Molecule Real-Time(SMRT)测序 平均读长~...
Segmental Duplication Assembler (SDA;) constructs graphs in which paralogous sequence variants define the nodes and long-read sequences provide attraction and repulsion edges, enabling the partition and assembly of long reads corresponding to distinct paralogs. We apply it to single-molecule, real-...
Use of custom‐made barcodes combined with PacBio RSII sequencing led to highly continuous assemblies of the LA (~100 kb) and MN (~200 kb) clusters, which include syntenic regions of coding and intergenic sequences. Our results revealed an overall conserved genomic organization of the Hb ...
a protein25, causes nonsense-mediated decay (NMD)88, contains repetitive elements93, is a transmembrane protein94, contains a domain motif95, contains a signal peptide96, or has intrinsically disordered regions (IDRs)97 in silico based on the nucleotide sequence obtained by long-read sequencing. ...
sequence. This correction method is allowed by the stochastic nature of PacBio errors, which decreases the possibility of having the same error in multiple subreads. Thus, discrepancy between subreads can be corrected with sufficient sequence coverage. Base calling is computationally intense; hence, ...
Long-read sequencing, or third-generation sequencing, offers a number of advantages over short-read sequencing [1,2]. While short-read sequencers such as Illumina’s NovaSeq, HiSeq, NextSeq, and MiSeq instruments [3–5]; BGI’s MGISEQ and BGISEQ models [6]; or Thermo Fisher’s Ion Tor...
Background: Numerous completed or on-going whole genome sequencing projects have highlighted the factthat obtaining a high quality genome sequence is necessary to address comparative genomics questions such as structural variations among genotypes and gain or loss of specific function. Despite the spectacu...
The current work describes our SSPACE-LongRead software which is designed to upgrade incomplete draft genomes using single molecule sequences. We conclude that the recent advances of the PacBio sequencing technology and chemistry, in combination with the limited computational resources required to run ...
Also, 49,093 long non-coding RNAs (lncRNAs) and 141,702 simple sequence repeats were identified. Based on full-length transcriptome sequencing, the present study found that the Toll-like receptor/nuclear factor kappa-B signaling pathway plays an important role in the development of SBM- and FS...
We established an analytical strategy based on the long-read sequences, and analyzed the complexity of HBV DNA integration into the hepatocellular genome. A total of 88 integrated breakpoints were identified. HBV DNA integration into human genomic DNA was mainly fragmented with different orientations,...
