This work discusses TE strategies to evade host silencing and ensure their long-term persistence within host genomes, focusing on insects as the primary model system, and postulates potential evasive mechanisms that may drive TE adaptation within host genomes.
Abstract
Transposable elements (TEs) are mobile genetic sequences that have long resided within host genomes. Over this shared history, a continuous process of co-evolution has forged a diverse array of dynamic TE-host interactions. In an evolutionary arms race, hosts must silence TEs to protect genome integrity from deleterious mutations by TE insertions, while TEs must evade this silencing to survive. TE adaptations to host genomes have recently gained prominence, following many discoveries in eukaryotic genomes. Here, I discuss TE strategies to evade host silencing and ensure their long-term persistence within host genomes, focusing on insects as the primary model system. Furthermore, by describing host silencing, I postulate potential evasive mechanisms that may drive TE adaptation within host genomes.
Transposable elements (TEs), originally characterized in maize, are ubiquitous features of eukaryotes and replicate within genomes independent of the host replication cycle. This replicative advantage can result in genomes that are almost entirely composed of these selfish genetic elements. Most mutations caused by TE...

It is argued that while host silencing mechanisms, such as the piRNA pathway, tightly regulate TE activity to minimize harmful effects, the context-dependent activation of active TEs can generate beneficial genetic variation that enhances insect adaptations to anthropogenic and climatic pressures.

Transposable elements (TEs) constitute a major fraction of eukaryotic genomes and represent one of the most abundant classes of repetitive sequences in plants. Recent advances in sequencing technologies, together with the increasing availability of telomere-to-telomere and pan-genome assemblies, have enabled comprehens...

As a fundamental biological principle, genomic information is typically transmitted vertically from parent to offspring. Occasionally, however, genetic material is transferred horizontally between species. Transposable elements (TEs) are frequently involved in such horizontal transfer (HT), possibly due to their abilit...

The findings demonstrate the broad-scale impact of TE-dependent genome evolution during ant adaptive radiation and suggest that similar comparative analyses across other major lineages will be worthwhile to reconstruct the wider macroevolutionary impact of TEs.

Evidence that genes acquired from microbes by plants facilitated critical adaptations in their terrestrialization, including stress tolerance, phytohormone signaling, cell wall biosynthesis, and defense against pathogens and herbivores is synthesized.
