Dynamic sequence evolution of a sex-Associated b chromosome in lake Malawi cichlid fish
(2017-01-01)
B chromosomes are extra chromosomes found in many species of plants, animals, and fungi. B chromosomes often manipulate common cellular processes to increase their frequency, sometimes to the detriment of organismal fitness. ...
Becoming a Selfish Clan: Recombination Associated to Reverse-Transcription in LTR Retrotransposons
(Oxford University Press, 2019-11)
Transposable elements (TEs) are parasitic DNA bits capable of mobilization and mutagenesis, typically suppressed by host's epigenetic silencing. Since the selfish DNA concept, it is appreciated that genomes are also molded ...
Addressing Long-Standing Questions with Advanced Approaches: The 4th B Chromosome Conference
(Karger, 2020-04-01)
B chromosomes (Bs) are enigmatic accessory genomic elements extensively characterized in diverse eukaryotes. Since their discovery in the beginning of the 20th century, B chromosomes have been the subject of investigation ...
Modulating signaling networks by CRISPR/Cas9-mediated transposable element insertion
(Springer, 2018-04)
In a recent past, transposable elements (TEs) were referred to as selfish genetic components only capable of copying themselves with the aim of increasing the odds of being inherited. Nonetheless, TEs have been initially ...
Male-killing Spiroplasma naturally infecting Drosophila melanogaster
(Wiley-blackwellMaldenEUA, 2005)
B chromosomes of multiple species have intense evolutionary dynamics and accumulated genes related to important biological processes
(2020-09-23)
Background: One of the biggest challenges in chromosome biology is to understand the occurrence and complex genetics of the extra, non-essential karyotype elements, commonly known as supernumerary or B chromosomes (Bs). ...
