Abstract

Transposable elements (i.e. insertion sequences and transposons) are components of nearly all bacterial genomes. The majority of these elements have been identified as a result of various sequencing projects. However, in most cases, their activity was not experimentally confirmed. For this reason several strategies have been developed that allow direct cloning and identification of functional transposable elements. Most of the methods are based on the ability of transposable elements to inactivate or activate particular genes by insertion. In this review we describe and critically discuss different cloning strategies that employ various entrapment vectors, carrying (i) conditionally lethal genes, (ii) antibiotic selection cartridges, (iii) promoter-less genes or (iv) suicide replicons. These tools, besides facilitating the identification of new transposable elements, also enable the investigation of various DNA rearrangement mutations, which are related to the transposition process.

Helitrons are enriched in lichenized fungi with long generation lengths and small distribution sizes.

Transposable elements have the potential to drive genome evolution by introducing mutations and causing structural instability and chromosomal rearrangements, particularly under conditions like environmental or genetic stress. In this study, we generated 18 new long-read-based metagenomically assembled reference genomes for lichenized fungi, which form obligate mutualistic symbioses with algae or cyanobacteria. We used the new genomes and 10 publicly available genomes to investigate the relationships between species traits (i.e. dominant reproductive mode, distribution size, and generation length) and the abundance and spatial distribution of transposable elements using a phylogenetic comparative framework. We found that species with smaller distribution sizes and longer generation lengths had a higher genomic DNA transposon load. Specifically, their genomes were enriched with Rolling Circle transposons, which contradict previous research that has identified high proportions of retrotransposons in rare species. Disproportionate distributions of transposable elements in rare and range-restricted species may disrupt genomic stability, decrease fitness, and be reflective of species experiencing a greater degree of stress. Conversely, greater transposable element activity may be an important source of novel genetic diversity in isolated populations with limited gene flow. Further research is needed to understand the potential mechanisms driving transposable element proliferation in rare species' genomes and if transposable element content is predictive of increased extinction risk.

Cooperation, competition and enforcement in transposon evolution.

Transposons are powerful drivers of genome evolution, but we lack a clear understanding of how these selfish genetic elements evolve and co-evolve with their hosts. Here, we develop a new general model of transposon-host co-evolution that incorporates key details of transposon and host biology. Our model reveals that the way that transposons replicate is critical for their evolutionary prognosis. Publicly-replicating transposons (such as DNA transposons), which cooperatively share their replication machinery, are predicted to be self-limiting. However, privately-replicating transposons (such as long interspersed nuclear elements, or LINEs), which do not replicate cooperatively, are under continual selection to increase their duplication rate even to the point of host extinction, a so-called tragedy of the commons. Neither selection against transposons' deleterious effects nor exploitation by parasitic elements is sufficient to prevent host extinction. Instead, our analysis shows that only active suppression by hosts avoids population collapse. In particular, suppression must act post-transcriptionally in order to prevent continuous escalation of the transposon-host genetic conflict. We argue that only with host enforcement of transposons can complex life exist.

The fungal RIP hypermutator mechanism has deep eukaryotic roots.

The repeat-induced point mutation (RIP) targets repeated sequences, such as transposable elements, in filamentous fungi. Host-transposable element coevolutionary dynamics have shaped taxonomically restricted eukaryotic defense systems, likely built on conserved ancestral mechanisms. Key questions surrounding homology recognition remain unresolved, and RIP offers a unique opportunity to answer them.
