Intraspecific comparative genomics of isolates of the Norway spruce pathogen (Heterobasidion parviporum) and identification of its potential virulence factors

BMC Genomics
PMCID: 5870257
PMID: 29580224
DOI: 10.1186/s12864-018-4610-4

[…] TEs in reference assembly were predicted using RepeatScout v.1.0.5 [], Nseg [], TRF [] and classified with REPCLASS v.1.0.1 [] and tblastx against Repbase Update database v.29.8.2016. Full-length long terminal repeat (LTR) retrotransposons were identified by LTRharvest [] and LTRdigest []. All detected cla […]


Improved Genome Assembly and Annotation for the Rock Pigeon (Columba livia)

PMCID: 5940132
PMID: 29519939
DOI: 10.1534/g3.117.300443

[…] rminal inverted repeats (TIRs), and detection of target site duplications (TSDs). Homology-based evidence was obtained using RepeatMasker (), as well as the homology module of the TE classifying tool RepClass (). RepClass was also used to identify signatures of transposable elements (TIRs, TSDs). We then eliminated non-TE repeats (simple repeats or gene families) using custom Perl scripts (availab […]


Using bioinformatic and phylogenetic approaches to classify transposable elements and understand their complex evolutionary histories

PMCID: 5718144
PMID: 29225705
DOI: 10.1186/s13100-017-0103-2

[…] rce for homology-based RepeatMasker annotation, which has a built-in classification tool, and employs four major subclasses (DNA, LTR, ERV, non-LTR), with further subdivisions into superfamilies. The RepClass classification tool employs four subclasses (DNA, LTR, non-LTR, Helitron), and identifies class (C), subclass (SC), and superfamily (SF), accounting for homology, structural features, and TSD […]


Genome analysis of Diploscapter coronatus: insights into molecular peculiarities of a nematode with parthenogenetic reproduction

BMC Genomics
PMCID: 5483258
PMID: 28646875
DOI: 10.1186/s12864-017-3860-x

[…] ion 3.1-snap20121016.1 and TRF version 4.0.4) and 17.4% of the 511 scaffolds (after cleaned up) were masked by the de novo modeled repeats or simple repeats. The 754 repeat sequences were analyzed by REPCLASS [] (version 1.0.1 with RepBase version 22.03, blast version 2.3.0, options for tblastx: -evalue 0.0001 -num_descriptions 10,000,000 -num_alignments 10,000,000 -seg yes and options for blastn: […]


Stella modulates transcriptional and endogenous retrovirus programs during maternal to zygotic transition

PMCID: 5404928
PMID: 28323615
DOI: 10.7554/eLife.22345.035

[…] ptional NH tags of all alignments in the SAM files were set to one and mapped reads were counted for each TE using htseq-count (). We show multi-mapped reads can be unambiguously assigned to a class (repClass in RepeatMasker) and family (repFamily in RepeatMasker) 98% of the time, however, only 54% of the time at the level of an element (repName in RepeatMasker) (). For this reason, all analysis a […]


Structure of the germline genome of Tetrahymena thermophila and relationship to the massively rearranged somatic genome

PMCID: 5182062
PMID: 27892853
DOI: 10.7554/eLife.19090.045

[…] and detection of Target Site Duplications (TSDs). Homology-based evidence was obtained using RepeatMasker Protein Mask () (RRID:SCR_012954), as well as the homology module of the TE classifying tool RepClass () (RRID:SCR_014654). Repclass was also used to identify some of the signatures of transposable elements (TIRs, TSDs). We then eliminated non-TE repeats (simple repeats or gene families). Fir […]
