Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges

Advanced Science, EarlyView.
Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...

Transposable Element Dynamics Drive the Genomic Evolution and Phenotypic Diversification of Allotetraploid Common Carp

Advanced Science, EarlyView.
By integrating 516 whole‐genome resequencing datasets and 236 transcriptomes of allotetraploid common carp, this study establishes the first population‐scale atlas of transposable element (TE) variation in teleost species. TE bursts, relaxed purifying selection, and lineage‐specific loss of ancient insertions shape genome evolution and phenotypic ...

Birth and Death of LTR-Retrotransposons in Aegilops tauschii [PDF]

Genetics, 2018
Abstract Dai et al. employed time-dynamic modeling for the insertion rate (birth) and the deletion rate (death) of long terminal repeat retrotransposons (LTR-RTs) in the Aegilops tauschii genome. They found that insertion rates of the 35...

Comprehensive DNA Methylation Analysis of Retrotransposons in Male Germ Cells

Cell Reports, 2015
De novo DNA methylation of retrotransposons is critical for silencing. Here, we use DNA methylation analysis to examine retrotransposons in mouse male germ cells.

Sorghum T2T pangenome highlights comprehensive genomic variation

iMetaOmics, EarlyView.
Three newly assembled telomere‐to‐telomere (T2T) genomes representing wild, landrace, and transformable germplasm were integrated with seven publicly available T2T genomes to construct a graph‐based pangenome. Comparative analyses revealed extensive centromere divergence, including distinct CEN137 monomer and CEN274 dimer organization, and showed that ...

Transposable Elements and Genome Size Variations in Plants [PDF]

Genomics & Informatics, 2014
Although the number of protein-coding genes is not highly variable between plant taxa, the DNA content in their genomes is highly variable, by as much as 2,056-fold from a 1C amount of 0.0648 pg to 132.5 pg.

Deciphering transcriptome complexity via long‐read sequencing

iMeta, EarlyView.
Long‐read sequencing is transforming transcriptomics from gene‐level quantification to isoform‐resolved interpretation by directly resolving full‐length transcript structures, transcription in repetitive regions, and linked molecular features. This review provides an end‐to‐end roadmap covering sequencing platforms, library preparation strategies ...

Exonization of the LTR transposable elements in human genome

BMC Genomics, 2007
Background Retrotransposons have been shown to contribute to evolution of both structure and regulation of protein coding genes. It has been postulated that the primary mechanism by which retrotransposons contribute to structural gene evolution is ...

Hagfish genome reveals parallel evolution of 7SL RNA-derived SINEs

Mobile DNA, 2020
Background Short interspersed elements (SINEs) are ubiquitous components of eukaryotic genomes. SINEs are composite transposable elements that are mobilized by non-long terminal repeat (non-LTR) retrotransposons, also called long interspersed elements ...

Transposons as Tools for Future Genome Engineering in Yeasts and Filamentous Fungi

Yeast, EarlyView.
Applications of transposon‐based tools for genome engineering in fungi include transposon‐mediated mutagenesis and targeted genomic integration. ABSTRACT Transposons are fundamental genetic elements that have profoundly shaped the architecture of eukaryotic genomes.
