LESS CRYPTIC. “In some cases, a sexual cycle has even been observed for apparently asexual species, such as for the saprotrophic and opportunistic mammalian pathogenic fungus Aspergillus fumigatus.” https://lnkd.in/eC8eb-V View in LinkedIn

TRANSFER RNA. “Moreover, genome rearrangements have been observed in proximity to highly abundant tRNA genes in yeast.” https://lnkd.in/eC8eb-V View in LinkedIn

FUNGAL SEXUAL GENES. “Comparative genomics identified many meiosis-specific genes, as well as the mating type locus that encodes genes that are critically required for sexual reproduction, in the apparently asexual fungus Candida glabrata, suggesting it has a cryptic sexual cycle.” https://lnkd.in/eC8eb-V View in LinkedIn

JUMPING GENES AND DIVERSITY. “Genome rearrangements are not only mediated by transposable elements, but also by other highly repetitive elements such as micro- and minisatellites; short nucleotide repeats that differ in the length of the repeat unit.” https://lnkd.in/eC8eb-V View in LinkedIn

CRYPTIC SEXUAL CYCLES. “Many fungal species have initially been considered to lack a conventional sexual cycle, and were thus seen as strictly asexual (clonal). However, several of these species were later discovered to have cryptic, hence hidden, sexual cycles, or other modes of reproduction.” https://lnkd.in/eC8eb-V View in LinkedIn

JUMPING GENES ROLE IN EVOLUTION. “In addition to these active roles, the major contribution of transposable elements toward genome evolution is passive. Non-faithful repair of double-strand DNA breaks is facilitated by highly similar sequences such as abundant or propagating transposable elements.” https://lnkd.in/eC8eb-V View in LinkedIn

IMPORTED GENES IN ROTIFER. “A. vaga has been subject to horizontal gene transfer as up to 8% of its genes are likely of non-metazoan origin, a frequency as high as reported for some bacteria. Frequent genomic rearrangements, gene conversion and horizontal gene transfers likely contribute to diversification and homogenization in the absence of sex, thereby revealing that sexual reproduction is not required for evolutionary success and persistence.” https://lnkd.in/eC8eb-V View in LinkedIn

PECULIAR ROTIFER CASE. “Asexual metazoan bdelloid rotifer Adineta vaga revealed a genomic structure that is dominated by genomic rearrangements, mainly through mitotic recombination. Interestingly, this structure is incompatible with meiotic recombination since allelic regions, that normally pair during meiosis, are rearranged.” https://lnkd.in/eC8eb-V View in LinkedIn

ALTERNATIVE SOLUTION. “Recent findings suggest that the absence of an obvious sexual lifestyle does not necessarily result in limited genetic diversity, and that in particular genomic rearrangements can foster adaptation.” https://lnkd.in/eC8eb-V View in LinkedIn

NO NEED FOR SEX. “Genome rearrangements foster evolution in the absence of sex.” https://lnkd.in/eC8eb-V View in LinkedIn
