Fast diploidization in close mesopolyploid relatives of Arabidopsis.
Mesopolyploid whole-genome duplication (WGD) was revealed in the ancestry of Australian Brassicaceae species with diploid-like chromosome numbers (n = 4 to 6). Multicolor comparative chromosome painting was used to reconstruct complete cytogenetic maps of the cryptic ancient polyploids. Cytogenetic analysis showed that the karyotype of the Australian Camelineae species descended from the eight ...
متن کاملPartial diploidization of meiosis in autotetraploid Arabidopsis thaliana.
Meiosis was analyzed cytogenetically in autotetraploids of Arabidopsis, including both established lines and newly generated autotetraploid plants. Fluorescent in situ hybridization with 5S and 45S rDNA probes was used to identify the different chromosomes at metaphase I of meiosis. Multivalents were observed frequently in all the lines analyzed, but there were significant differences in multiv...
متن کاملLife and Its Close Relatives
When driven by an external thermodynamic gradient, nonbiological physical systems can exhibit a wide range of behaviours usually associated with living systems. Consequently, Artificial Life researchers should be open to the possibility that there is no hard-and-fast distinction between the biological and the physical. This suggests a novel field of research: the application of biologists’ meth...
متن کاملComparing the linkage maps of the close relatives Arabidopsis lyrata and A. thaliana.
We have constructed a genetic map of Arabidopsis lyrata, a self-incompatible relative of the plant model species A. thaliana. A. lyrata is a diploid (n = 8) species that diverged from A. thaliana (n = 5) approximately 5 MYA. Mapping was conducted in a full-sib progeny of two unrelated F(1) hybrids between two European populations of A. lyrata ssp. petraea. We used the least-squares method of th...
متن کاملPsoriasis and vitiligo are close relatives
BACKGROUND Both vitiligo and psoriasis are chronic inflammatory autoimmune diseases with genetic elements. OBJECTIVE To estimate the frequencies of psoriasis in vitiligo patients and vice versa and to compare them with healthy controls. PATIENTS AND METHODS A total of 1000 subjects were included, 250 of them had vitiligo, 250 had psoriasis, and 500 were healthy controls. Measurement of the ...
