The hobo transposable element can occur under three forms in the Drosophila genome: as a complete element (also called canonical), as internally deleted copies, or as hobo-related sequences (relics). Some evidence indicated that canonical elements and internally deleted copies are recent acquisitions of Drosophila genomes, while the “relics” are old components, normally degenerated and immobile. Here we present the characterization of a hobo-related sequence, found in the genome of a… Expand
The hobo transposon and hobo-related elements are expressed as developmental genes in Drosophila.
TLDR
It is suggested that cis-regulatory sequences similar to those in developmental genes exist in hobo sequences, and hobo mobilization may contribute to the development of new regulatory networks during genomic evolution. Expand
Drosophila relics hobo and hobo-MITEs transposons as raw material for new regulatory networks
Abstract Hypermutable strains of Drosophila simulans have been studied for 20 years. Several mutants were isolated and characterized, some of which had phenotypes associated with alteration inExpand
Unraveling the evolutionary scenario of the hobo element in populations of Drosophila melanogaster and D. simulans in South America using the TPE repeats as markers
TLDR
An evolutionary scenario of the invasion of the hobo element in populations of D. melanogaster and D. simulans is proposed and shown a monomorphism in population of both species in South America, with only three TPE repeats. Expand
The hobo-related elements in the melanogaster species group.
TLDR
Using this sequence as the initial seed to search for homologous sequences in 12 available Drosophila genomes, in addition to searching for these sequences by PCR and Southern blot in nine other species, these hRSs and their 'MITE-like' counterparts could provide a good example of the steps proposed in models that describe the MITEs origin.

DNA sequence requirements for hobo transposable element transposition in Drosophila melanogaster
TLDR
A structure and functional analysis of the hobo transposable element of Drosophila melanogaster and compared target site sequences of hobo with those of the related Hermes element and found both transposons have strong preferences for the same insertion sites. Expand
BuT2 Is a Member of the Third Major Group of hAT Transposons and Is Involved in Horizontal Transfer Events in the Genus Drosophila
TLDR
The hAT superfamily comprises a large and diverse array of DNA transposons found in all supergroups of eukaryotes and it is found that the Drosophila buzzatii BuT2 element harbors a five-exon gene encoding a 643-aa putatively functional transposase. Expand
General survey of hAT transposon superfamily with highlight on hobo element in Drosophila
TLDR
The hAT transposons, very abundant in all kingdoms, have a common evolutionary origin probably predating the plant-fungi-animal divergence, and their domestication and use as transgenic tools are discussed. Expand

TLDR
It is suggested that full-size hobo-elements with a high activity level (less often with a mean activity level) are responsible for delayed deleterious irradiation effects. Expand
Analysis of phenotypes altered by temperature stress and hipermutability in Drosophila willistoni
TLDR
The results indicate that the D. willistoni 17A2 strain is a candidate for hypermutability, which presents considerable cryptic genetic variability, and different factors may be operating for the formation of this effect. Expand

Wanderings of Hobo: A Transposon in Drosophila Melanogaster and its Close Relatives
TLDR
There appear to have been a minimum of two introductions of hobo into the melanogaster subgroup, and more likely three, two ancient and one quite recent, followed by transfers between the extant species (whether ‘horizontally’ or by infrequent interspecific hybridization). Expand
The evolutionary genetics of the hobo transposable element in the Drosophila melanogaster complex.
TLDR
It is suggested that complete hobo elements were absent prior to 50 years ago and that they have recently been introduced into this species by horizontal transfer, and the hypothesis of multiple transfers in the recent past into the D. melanogaster complex from a common outside source is discussed. Expand
Sequences homologous to the hobo transposable element in E strains of Drosophila melanogaster.
TLDR
The results suggest that these ubiquitous hobo-homologous sequences are immobile and are distantly related to the modern hobo elements from D. melanogaster. Expand
The structure of hobo transposable elements and their insertion sites
TLDR
Structural similarities between hobo and the eukaryotic transposable elements P, Ac, 1723, and Tam3, found in widely divergent host organisms, suggest that they all transpose by a common mechanism. Expand

TLDR
DNA sequences reveal an extremely low level of divergence and support the conclusion that the active hobo element has been horizontally transferred into or among these species in the recent past. Expand
Distribution of hobo transposable elements in natural populations of Drosophila melanogaster.
TLDR
Comparison of data from the I-R and P-M systems suggests that the putative invasion followed the introduction of the I element but preceded that of the P element, which poses the problem of the plausibility of three virtually simultaneous element invasions in this species. Expand
hobo transposable elements in Drosophila melanogaster and D. simulans.
TLDR
Genomic patterns of occurrence of the transposable element hobo are polymorphic in the sibling species Drosophila melanogaster and D. simulans, which implies that an hypothesis of recent introduction in the latter species is inadequate to explain the phylogenetic occurrence of hobo. Expand
Geographical and historical patterns of distribution of hobo elements in Drosophila melanogaster populations
TLDR
A temporal survey of D. melanogaster strains using Southern blotting and the squash blot method which determines the presence of hobo sequences in individual flies and is suitable for use in population studies is reported. Expand
The hobo transposable element of Drosophila can be cross-mobilized in houseflies and excises like the Ac element of maize.
TLDR
The hobo transposable element from Drosophila melanogaster was found to be capable of excision, resulting in donor sites unlike those reported for any other transposability element currently known in animals, and appears to be a mobile-element system related to hobo, Ac, and Tam3. Expand
Identification of a fully‐functional hobo transposable element and its use for germ‐line transformation of Drosophila.
TLDR
The hobo transformation system will allow us to determine the structural and regulatory features of hobo responsible for its mobilization and will provide novel approaches for the molecular and genetic manipulation of the Drosophila genome. Expand
