The past 10 years have been productive in the characterization of fungal transposable elements (TEs). All eukaryotic TEs described are found including an extraordinary prevalence of active members of the pogo family. The role of TEs in mutation and genome organization is well documented, leading to significant advances in our perception of the mechanisms underlying genetic changes in these organisms. TE-mediated changes, associated with transposition and recombination, provide a broad range of… 

Biology, dynamics, and applications of transposable elements in basidiomycete fungi

This mini-review surveyed and explored data from 75 genomes, which encompass the phylogenetic diversity of the phylum Basidiomycota, and reviewed the most relevant literature about the role of TEs in species lifestyle, their impact on genome architecture and functionality, and the defense mechanisms evolved to control their proliferation.

The biology and potential for genetic research of transposable elements in filamentous fungi

The application of transposable elements to gene isolation and population analysis is an important tool for molecular biology and studies of fungal evolution.

DNA transposons and the evolution of eukaryotic genomes.

This review focuses on DNA-mediated or class 2 transposons and emphasizes how this class of elements is distinguished from other types of mobile elements in terms of their structure, amplification dynamics, and genomic effect.

Transposon- and genome dynamics in the fungal genus Neurospora: insights from nearly gapless genome assemblies

This study suggests that TEs and RIP are highly correlated in Neurospora, and hence, the pattern of interaction is conserved over the investigated evolutionary timescale, and shows that RIP signatures can be used to facilitate the identification of TE-rich region in the genome.

Chromosomal rearrangements with stable repertoires of genes and transposable elements in an invasive forest-pathogenic fungus

This genome comparison detected several large chromosomal rearrangements that may have important consequences in gene regulations and sexual mating in this invasive species, which opens the way for more comparisons of high-quality assembled genomes, and questions the role of structural variations in the invasive success of this fungal pathogen species.

Recent invasion of P transposable element into Drosophila yakuba

It is found that PEs invaded the genome of D. yakuba, an African species, in just 8 years, the frequency of the PEs increased from 0% to 18% but then decreased to 2%, shows that PE invasions can be transient.

Recent transposable element bursts triggered by insertions near genes in a fungal pathogen

This work shows how specific genomic environments features provide triggers for TE proliferation, and found that a Copia element burst was initiated from recent copies inserted substantially closer to genes compared to older insertions.

Abundance, distribution and potential impact of transposable elements in the genome of Mycosphaerella fijiensis

The analysis of TEs in M. fijiensis suggests that TEs play an important role in the evolution of this organism because the activity of these elements, as well as the rearrangements caused by ectopic recombination, can result in deletion, duplication, inversion and translocation.

Fungal evolutionary genomics provides insight into the mechanisms of adaptive divergence in eukaryotes

The various ecological sources of divergent selection and genomic changes are outlined, showing that gene loss and changes in gene expression and in genomic architecture are important adaptation processes, in addition to the more widely recognized processes of amino acid substitution and gene duplication.

Transposon-Mediated Horizontal Transfer of the Host-Specific Virulence Protein ToxA between Three Fungal Wheat Pathogens

The extent of horizontally transferred DNA is defined between three fungal wheat pathogens as part of a conserved ∼14 kb element which contains coding and noncoding regions and is the first description of ToxA with complete transposon features, which is called ToxhAT.



Fungal transposable elements and genome evolution

Understanding of the biological effects of TEs on the fungal genome has increased dramatically in the past few years but elucidation of the extent to which transposons contribute to genetic variation in nature, providing the flexibility for populations to adapt successfully to environmental changes is an important area for future research.

This work focuses on the potential of transposons for tagging and identifying fungal genes, and presents structural and functional features for such transposon that have been identified so far in filamentous fungi.

Transposable elements in the fungal plant pathogenFusarium oxysporum

Comparisons of the distribution of transposable elements in Fusarium populations have improved the understanding of population structure and epidemiology and provided support for horizontal genetic transfer.

Repetitive DNA elements in fungi (Mycota): impact on genomic architecture and evolution

This survey summarises the main characteristics of well studied experimental systems and intends to define important open questions for stimulating future research.

Evolution of DNA Transposons in Eukaryotes

This chapter focuses on DNA transposons in eukaryotic genomes and particularly the four available genomes from plants and animals and what recent eukARYotic genomic sequences tell us about the history of DNA transPOSons.

Potential role of transposable elements in the rapid reorganization of the Fusarium oxysporum genome.

It is suggested that chromosome length polymorphisms likely result from ectopic recombination between TEs that can serve as substrates for these changes, and that EK differences result from chromosomal translocations, large deleting, and even more complex rearrangements.

Genome organization in Fusarium oxysporum: clusters of class II transposons

Sequence analysis of contiguous stretches of genomic DNA surrounding insertion sites of one family of transposable elements revealed that they are packed with repeated sequences.

The evolutionary life history of P transposons: from horizontal invaders to domesticated neogenes

Tracing the fate of P transposons on an evolutionary scale is described, finding that the initial transpositional burst in the new host is slowed down by the accumulation of defective copies as well as host-directed epigenetic silencing, which leads to the loss of mobility and, finally, to molecular erosion by random mutations.

New modes of genetic change in filamentous fungi.

Analysis of recombination of traits such as phytoalexin detoxification and mela­ nin biosynthesis in plant pathogenic fungi confirmed the role of these factors in pathogenicity.

Modern thoughts on an ancyent marinere: function, evolution, regulation.

Two mechanisms that may be operative in mariner regulation are identified, one mechanism is overproduction inhibition, in which excessive wild-type transposase reduces the rate of excision of a target element, and a second mechanism is dominant-negative complementation, inwhich certain mutant transpos enzyme proteins antagonize the activity of the wild- type transposable elements.
