Long terminal repeat retrotransposons (LTR-RTs) represent a major fraction of plant genomes, but processes leading to transposition bursts remain elusive. Polyploidy expectedly leads to LTR-RT proliferation, as the merging of divergent diploids provokes a genome shock activating LTR-RTs and/or genetic redundancy supports the accumulation of active LTR-RTs through relaxation of selective constraints. Available evidence supports interspecific hybridization as the main trigger of genome dynamics…

An Eruption of LTR Retrotransposons in the Autopolyploid Genomes of Chrysanthemum nankingense (Asteraceae)

Results suggest a need to expand the current evolutionary framework to include a genetic dimension when seeking to understand genomic shock following autopolyploidization in Asteraceae, and suggest that fluorescence in situ hybridization(FISH) results suggest that autopolyPLoidization might also be accompanied by perturbations of LTR retrotransposons, and emergence Retrotransposon insertions might show more rapid divergence, resulting in diploid-like behaviour.

Resolving fine‐grained dynamics of retrotransposons: comparative analysis of inferential methods and genomic resources

Examining the pitfalls and benefits of approaches relying on different genomic resources, it is highlighted that random sequencing reads represent adequate data suitably complementing biased samples of LTR-RT copies retrieved from assembled genomes towards comprehensive surveys of the biology of transposition elements.

Evolutionary Dynamics of Transposable Elements Following a Shared Polyploidization Event in the Tribe Andropogoneae

The lack of copia insertions near the orthologous genes in S. bicolor suggests that duplicate gene copies generated during polyploidization may offer novel neutral sites for TEs to insert, thereby providing an avenue for subfunctionalization via TE insertional mutagenesis.

Transposable element over-accumulation in autopolyploids results from relaxed purifying selection and provides variants for rapid local adaptation

It is demonstrated that relaxed purifying selection rather than transposition bursts is the main driver of TE over-accumulation after WGD and indicates that tetrasomy by itself leads to an enhanced tolerance to accumulating genic TE variants, some of which can potentially contribute to local adaptation.

Nuclear Genome Size is Positively Correlated with Median LTR-RT Insertion Time in Fern and Lycophyte Genomes

It is found that similar to seed plants, median LTR-RT insertion times were strongly correlated with haploid nuclear genome size, and these results are consistent with other patterns of structural variation in fern and lycophyte genomes.

Relaxed purifying selection in autopolyploids drives transposable element over-accumulation which provides variants for local adaptation

The authors show that following whole genome duplication, relaxed purifying selection is the main driver of TE over-accumulation, which provides variants for rapid local adaptation.

Parental transposable element loads influence their dynamics in young Nicotiana hybrids and allotetraploids.

The correlation between transposable element mobilisation in allopolyploids and quantitative imbalances in parental transposability element loads supports the genome shock hypothesis proposed by McClintock.

The “Polyploid Hop”: Shifting Challenges and Opportunities Over the Evolutionary Lifespan of Genome Duplications

Evidence suggests that if early barriers are overcome, WGD can offer instantaneous fitness advantages opening the way to a transformed fitness landscape by sampling a higher diversity of alleles, including some already preadapted to their local environment.

Repeated Whole-Genome Duplication, Karyotype Reshuffling, and Biased Retention of Stress-Responding Genes in Buckler Mustard

Analysis of repeated WGD events and genome reshuffling supporting preferential retention of stress-responding duplicates showing a signature of strong purifying selection and retention of large stretches of chromosomes for both genomic copies supported the hypothesis that cycles of WGD and biased fractionation shaped the genome of this stress-tolerant polypolyloid.

Genomics of Evolutionary Novelty in Hybrids and Polyploids

This work focuses on the types of molecular genetic and genomic processes that might be set in motion by the saltational event of genome merger between two diverged species, either with or without genome doubling, and how these various processes can contribute to novel phenotypes.



Contrasting evolutionary trajectories of multiple retrotransposons following independent allopolyploidy in wild wheats.

Overall, TE divergence between progenitors was strongly correlated with the degree of restructuring in polyploid TE fractions, and TE families present evolutionary trajectories that are decoupled from genome-wide changes after allopolyploidy and have a pervasive impact on their restructuring.

Evolutionary Dynamics of Retrotransposons Assessed by High-Throughput Sequencing in Wild Relatives of Wheat

An approach bypassing the required step of a complete reference genome to assess the evolutionary trajectories of high copy number TE families from genome snapshot with high-throughput sequencing, allowing to address the genome-wide evolutionary dynamics of TEs at the family level and advancing the understanding of the evolution of nonmodel genomes.

Evolutionary conservation, diversity and specificity of LTR-retrotransposons in flowering plants: insights from genome-wide analysis and multi-specific comparison.

The hypothesis of a single ancient origin of envelope-like genes in the putative Copia retrovirus-like family is proposed, and thus the availability of complete or nearly complete genome sequences from several plant species permits detailed discovery and cross-species comparison of transposable elements at the whole genome level.

The dynamics of LTR retrotransposon accumulation across 25 million years of panicoid grass evolution

Results suggest random activation of a few or many LTR retrotransposons families in particular lineages over evolutionary time, with some families especially prone to future activation and hyper-amplification.

Comparative Genomic Paleontology across Plant Kingdom Reveals the Dynamics of TE-Driven Genome Evolution

It is shown that retrotransposition has recurrently occurred in all plant genomes investigated, regardless their size, and through bursts, rather than a continuous process, which leads to a new model of TE-driven genome evolution in plants.

Shifts in the evolutionary rate and intensity of purifying selection between two Brassica genomes revealed by analyses of orthologous transposons and relics of a whole genome triplication.

The authors' analyses suggest that local genomic and epigenomic features, such as recombination rates and chromatin dynamics reshaped by independent proliferation of transposable elements and elimination between the two genomes, are perhaps partially the causes and partially the outcomes of the observed inter-specific asymmetric evolution.

Natural Pathways to Polyploidy in Plants and Consequences for Genome Reorganization

The last decade highlighted polyploidy as a rampant evolutionary process that triggers drastic genome reorganization, but much remains to be understood about their causes and consequences in both

Impact of transposable elements on the organization and function of allopolyploid genomes.

Transposable elements (TEs) represent an important fraction of plant genomes and are likely to play a pivotal role in fuelling genome reorganization and functional changes following allopolyploidization, but available evidence indicates that TE proliferation in the short or the long term after allopolyPloidization may be restricted to a few TEs.

How Athila retrotransposons survive in the Arabidopsis genome

It is shown that recombination events among distantly related Athila retrotransposons have led to the generation of new Athila lineages, which suggests that Athila elements survive in Arabidopsis by a combination of selfish replication and of amplification of highly diverged copies with coding potential.
