What are flanking sequences
Here, we describe Flanker, a simple, reference-free tool to investigate MGEs by analysing the flanking sequences of ARGs. The flanking sequences (hereafter, flanks) around an ARG that has been mobilized horizontally may act as signatures of relevant MGEs and support epidemiological analyses.12 juil. 2018 ... You can use seqkit subseq with -d (for downstream seq) and -u (for upstream sequence) option or "--only-flank" option to get only up/down ...This promoter has internal control sequences. Deletion of 5' flanking DNA still permits efficient transcription of (most) genes transcribed by RNA PolIII. Even the intial part of the gene is expendable, as is the 3' end. Sequences internal to the gene (e.g. +55 to +80 in 5S rRNA genes) are required for efficient initiation, in contrast to the ...

Centromere locations in these two genome assemblies were defined based on synteny with centromere flanking regions (SI Appendix, Table S2). Specifically, BLASTn analysis with centromere-flanking open reading frame sequences as query sequences were used to identify the syntenic regions defining the boundary for centromeres.The 2–4 bp flanking sequences of each G-box or G-box variant in the GmScream3 promoter were changed to match the native flanking sequence of the classical G-box in EF4 (Figure 2a), which was previously demonstrated to confer high gene expression in synthetic promoters using both transient and stable expression assays (Figures 2-5). Analysis of sequences flanking T-DNA. Positions of the T-DNA insertions were deduced from the results of homology alignment of each FST against the TIGR assembly of rice chromosomes 1–12 (sequence accessions AP008207 to AP008218) using the blast N program. The vector sequence was masked prior to this homology search.
Here, we examine two flanking sequences bordering a site in the γ-fibrinogen gene regulatory region that binds a heterodimer of the Xenopus glucocorticoid receptor accessory factor (XGRAF) and the glucocorticoid receptor (GR). Mutation of the upstream flank results in a decrease in XGRAF binding, but little change in hormone induction.By targeting unique flanking genomic sequences with pairs of guide RNAs, pseudogenes can be specifically deleted without risk of mutating their parental genes (Fig. 4c).
