Bdelloid rotifers revisited.
S exual reproduction is one of the most striking features of the biological world. The great majority of the animals and plants with which we are most familiar reproduce at least part of the time by means of sexual reproduction with meiosis, recombination, and fertilization. But many eukaryotes reproduce asexually part of the time, and some are exclusively asexual (1, 2). Two articles in a rece...
متن کاملEvidence for meiotic sex in bdelloid rotifers
In their study of genetic exchange in the bdelloid rotifer Adineta vaga, Debortoli et al. [1] conclude that the patchwork pattern of allele sharing among three individuals in the genomic regions they examined is "…unlikely to arise in cases of PTH (Oenothera-like) meiosis since haplotypes are transferred as entire blocks…" and therefore that "Genetic exchange among bdelloid rotifers is more lik...
متن کاملEvidence for degenerate tetraploidy in bdelloid rotifers.
Rotifers of class Bdelloidea have evolved for millions of years apparently without sexual reproduction. We have sequenced 45- to 70-kb regions surrounding the four copies of the hsp82 gene of the bdelloid rotifer Philodina roseola, each of which is on a separate chromosome. The four regions comprise two colinear gene-rich pairs with gene content, order, and orientation conserved within each pai...
متن کاملAnhydrobiosis without trehalose in bdelloid rotifers.
Eukaryotes able to withstand desiccation enter a state of suspended animation known as anhydrobiosis, which is thought to require accumulation of the non-reducing disaccharides trehalose (animals, fungi) and sucrose (plants), acting as water replacement molecules and vitrifying agents. We now show that clonal populations of bdelloid rotifers Philodina roseola and Adineta vaga exhibit excellent ...
متن کاملIndependently Evolving Species in Asexual Bdelloid Rotifers
Asexuals are an important test case for theories of why species exist. If asexual clades displayed the same pattern of discrete variation as sexual clades, this would challenge the traditional view that sex is necessary for diversification into species. However, critical evidence has been lacking: all putative examples have involved organisms with recent or ongoing histories of recombination an...
