Family C of Short Interspersed Elements in the Genomes of Lagomorphs: Structure, Evolution, Transcription and Transcript Polyadenylation

Animals
Short Interspersed Elements (SINEs) are eukaryotic non-autonomous retrotransposons that rely on RNA polymerase III (pol III) for transcription. A subset of mammalian SINEs—designated T+ SINEs—harbors a canonical polyadenylation signal (AATAAA), a pol III

The rhg1‐a (Rhg1 low‐copy) nematode resistance source harbors a copia‐family retrotransposon within the Rhg1‐encoded α‐SNAP gene

Plant Direct, 2019
Soybean growers widely use the Resistance to Heterodera glycines 1 (Rhg1) locus to reduce yield losses caused by soybean cyst nematode (SCN). Rhg1 is a tandemly repeated four gene block.

Genomic variation drives plant flavor diversification

Journal of Integrative Plant Biology, EarlyView.
This review explains how genomic variation shapes plant flavor by altering the biosynthetic and regulatory pathways of key attributes like sweetness, acidity, bitterness, piquancy, astringency, and aroma. It also discusses how multi‐omics, AI‐assisted breeding, and gene editing can translate this knowledge into plants with improved flavor, nutrition ...

The Mytilus chilensis Steamer-like Element-1 Retrotransposon Antisense mRNA Harbors an Internal Ribosome Entry Site That Is Modulated by hnRNPK

Viruses
LTR-retrotransposons are transposable elements characterized by the presence of long terminal repeats (LTRs) directly flanking an internal coding region. They share genome organization and replication strategies with retroviruses. Steamer-like Element-1 (

Repeats as global DNA methylation marker in bovine preimplantation embryos

Czech Journal of Animal Science, 2017
DNA methylation undergoes dynamic changes and is a crucial part of the epigenetic regulation during mammalian early development. To determine the DNA methylation levels in bovine embryos, we applied a bisulfite sequencing based method aimed at repetitive

Epigenetic Requirements for Triggering Heterochromatinization and Piwi-Interacting RNA Production from Transgenes in the Drosophila Germline

Cells, 2020
Transgenes containing a fragment of the I retrotransposon represent a powerful model of piRNA cluster de novo formation in the Drosophila germline. We revealed that the same transgenes located at different genomic loci form piRNA clusters with various ...

High‐quality genome of elite peanut cultivar ZH05 reveals subgenome asymmetry, pan‐genome diversity, and breeding insights

Journal of Integrative Plant Biology, EarlyView.
A high‐quality reference genome for the elite peanut cultivar Zhonghua No. 5 revealed differing evolutionary paths between the two peanut subgenomes. SubA has higher overall gene expression and more open chromatin, whereas SubB has stronger structural organization, higher DNA methylation, and greater adaptive diversity associated with peanut evolution ...

Sukkula retrotransposon movements in the human genome

, 2017
Retrotransposons, a subclass of mobile genetic elements, have been discovered in many organisms. In this study, we identified a plant-specific retrotransposon (Sukkula) in the human genome (24 different DNA samples) by using retrotransposon-based ...

Recent advances in the genomics of sugarcane (Saccharum)

Journal of Integrative Plant Biology, EarlyView.
This review systematically summarizes advances in sugarcane genomics, evolution, classification, and breeding practices. It identifies key research bottlenecks and proposes an integrated research framework to facilitate predictive sugarcane breeding, which provides valuable references for genetic improvement of other complex polyploid crops.
