Insects are major contributors to our understanding of the interaction between transposable elements (TEs) and their hosts, owing to seminal discoveries, as well as to the growing number of sequenced insect genomes and population genomics and functional studies. Insect TE landscapes are highly variable both within and across insect orders, although phylogenetic relatedness appears to correlate with similarity in insect TE content. This correlation is unlikely to be solely due to inheritance of… 

Comprehensive mapping of transposable elements reveals distinct patterns of element accumulation on chromosomes of wild beetles

The remarkable variability of their genomic distribution suggests that TEs are likely candidates to contribute to the evolution of heterochromatin architecture and promote high genetic variability in species that otherwise display conserved karyotypes.

Dissecting cricket genomes for the advancement of entomology and entomophagy

This review is expected to enhance greater recognition of how important the cricket genomes are to the multiple biological fields and how basic research based on cricket genome information can contribute to tackling global food security.

A Genomic Survey of Mayetiola destructor Mobilome Provides New Insights into the Evolutionary History of Transposable Elements in the Cecidomyiid Midges

De novo annotation carried out using REPET pipeline showed that TEs occupy approximately 16% of the genome and are represented by 1038 lineages and Class II elements were the most frequent and most TEs were inactive due to the deletions they have accumulated.

The genome of the cereal pest Sitophilus oryzae: a transposable element haven

Reconstruction of host-symbiont metabolic networks revealed that, despite its recent association with cereal weevils (30 Kyear), S. pierantonius relies on the host for several amino acids and nucleotides to survive and to produce vitamins and essential amino-acids required for insect development and cuticle biosynthesis.

Repetitive elements in the era of biodiversity genomics: insights from 600+ insect genomes

The findings suggest this RE-annotation bottleneck, driven largely by uneven taxonomic representation in RE reference databases, is worsening and the tremendous opportunity and need for the field of biodiversity genomics to embrace REs is highlighted and collective steps for making progress are suggested.

Genome size evolution in the diverse insect order Trichoptera

Strong evidence is found that repetitive element (RE) expansions, particularly those of transposable elements (TEs), are important drivers of large caddisfly genome sizes and expanded genomes preferentially evolved in caddisflies clades with a higher ecological diversity.

Characterization of transposable elements within the

The characterization of these elements within the three whitefly genomes shows that TEs occupy significant portions of B. tabaci genomes, with DNA transposons representing the vast majority.

Expression Plasticity of Transposable Elements Is Highly Associated with Organismal Re-adaptation to Ancestral Environments

This study re-analyzed the transcriptomic data of chicken generated from a reciprocal transplant experiment and suggests a regulatory functions of TEs in this process, which supports the general function of phenotypic plasticity in adaptive evolution, and suggests the associated TEs co-expressed with diverse genes to perform a regulatory activity.

The Tetragnatha kauaiensis Genome Sheds Light on the Origins of Genomic Novelty in Spiders

The findings reveal that spider genomes are highly variable and that genomic novelty may have been driven by the burst of an ancient whole genome duplication, followed by gene family and transposable element expansion.
