DNA sequencing was performed on up to 12 chloroplast DNA regions [giving a total of 4288 base pairs (bp) in length] from the allopolyploid Arabidopsis suecica (48 accessions) and its two parental species, A. thaliana (25 accessions) and A. arenosa (seven accessions). Arabidopsis suecica was identical to A. thaliana at all 93 sites where A. thaliana and A. arenosa differed, thus showing that A. thaliana is the maternal parent of A. suecica. Under the assumption that A. thaliana and A. arenosa… 

A unique recent origin of the allotetraploid species Arabidopsis suecica: Evidence from nuclear DNA markers.

It is likely that A. suecica has a recent, unique origin between 12,000 and 300,000 years ago and migrated north, perhaps in the wake of the retreating ice.

The evolutionary history of the common chloroplast genome of Arabidopsis thaliana and A. suecica

The evolutionary history of the common chloroplast genome of the allotetraploid Arabidopsis suecica and its maternal parent A. thaliana was investigated, suggesting that the entire species originated during, or before, this period of time, although the estimates are sensitive to assumptions made about population size and mutation rate.

The origin of populations of Arabidopsis thaliana in China, based on the chloroplast DNA sequences

The dimorphism in the chloroplast DNA could be due to founder effects during late Pleistocene glaciations and interglacial periods, although introgression cannot be ruled out.

Evolution and genetic differentiation among relatives of Arabidopsis thaliana

It is concluded that A. thaliana is clearly separated phylogenetically from the x=8 lineage, five major lineages outside A.Thaliana can be identified, and centers of genetic and morphological diversity are mostly in congruence and are located close to the Balkans in Austria and Slovakia outside glaciated and permafrost regions with few notable exceptions.

Genome Sequencing Reveals the Origin of the Allotetraploid Arabidopsis suecica

This work identifies ubiquitous shared polymorphism with the parental species, and hence conclusively reject a unique origin in favor of multiple founding individuals of Arabidopsis suecica, and estimates that the species originated after the last glacial maximum in Eastern Europe or central Eurasia.

Further insights into the phylogeny of Arabidopsis (Brassicaceae) from nuclear Atmyb2 flanking sequence.

Chloroplast DNA insertions into the nuclear genome of rice: the genes, sites and ages of insertion involved

The studies indicate that the most chloroplast insertions occurred at a nuclear region characterized by a sharp change of repetitive sequence density, and suggest that rice might follow the non-homologous end-joining (NHEJ) repair of double-stranded breaks mechanism, which is suggested to be common to all eukaryotes.

Evolution of chloroplast mononucleotide microsatellites in Arabidopsis thaliana

The mode of evolution of the chloroplast mononucleotide microsatellites was best described by a linear relation between repeat length and mutation rate, when the repeat lengths exceeded about 7 bp, and it was found that the number of uninterrupted repeat units had a large impact on the level ofchloroplast microsatellite variation.

Intrageneric phylogeny of Capsella (Brassicaceae) and the origin of the tetraploid C. bursa-pastoris based on chloroplast and nuclear DNA sequences.

This study is the first of a wild, nonmodel plant genus that uses a combination of chloroplast and multiple low-copy nuclear loci for phylogenetic inference of polyploid evolution and does not lend support to previous hypotheses on the origin of C. bursa-pastoris.

Chromosomal locus rearrangements are a rapid response to formation of the allotetraploid Arabidopsis suecica genome

Observations suggest that some, but not all, loci are unstable in newly formed A. suecica allotetraploids and can participate in a variety of alternative rearrangements, some of which resemble chromosomal changes found in nature.



Genetic variation in Arabidopsis suecica and its parental species A. arenosa and A. thaliana.

Random amplified polymorphic DNA (RAPD) markers were used to estimate the level of genetic variation in Swedish accessions of the allopolyploid Arabidopsis suecica and its parental species A.

Analysis of a repetitive DNA family from Arabidopsis arenosa and relationships between Arabidopsis species

Using Southern hybridization and in situ hybridization, it is given evidence that A. suecica is a hybrid of A. thaliana and A. arenosa.

Nucleotide variation at the CHALCONE ISOMERASE locus in Arabidopsis thaliana.

Comparison of silent polymorphism and divergence at the CHI region and at the Adh1 and ChiA revealed in some cases a significant deviation of the direct relationship predicted by the neutral theory, which would be compatible with balancing selection acting at the latter regions.

DNA polymorphism at the cytosolic phosphoglucose isomerase (PgiC) locus of the wild plant Arabidopsis thaliana.

Investigation of DNA variation in a 4.7-kb region of the cytosolic phosphoglucose isomerase (PgiC) locus of Arabidopsis thaliana suggested positive selection for the Fast allozyme of the PGIC in A.Thaliana.

Rates of Nucleotide Substitution in Angiosperm Mitochondrial DNA Sequences and Dates of Divergence Between Brassica and Other Angiosperm Lineages

Abstract. We obtained 16 nucleotide sequences (∼1400 bp each) of the first intron of the mitochondrial (mt) gene for NADH subunit 4 (nad4) from 10 species of Brassicaceae. Using these new sequences

Allopolyploid Origin of Arabidopsis suecica (Fries) Norrlin: Evidence from Chloroplast and Nuclear Genome Markers

Analysis of the maternally inherited cpDNA provided strong evidence for A. thaliana as maternal parent and the isozyme data suggest multiple origin of A. suecica, because the alloploid shows polymorphisms at the same loci that are polymorphic in its progenitors.

RFLP and Cytogenetic Evidence on the Origin and Evolution of Allotetraploid Domesticated Peanut, Arachis hypogaea (Leguminosae)

RFLP and cytogenetic evidence indicate a single origin for domesticated peanut in Northern Argentina or Southern Bolivia, followed by diversification under the influence of cultivation.

Phenotypic Instability and Rapid Gene Silencing in Newly Formed Arabidopsis Allotetraploids

Evidence that gene silencing accompanies allopolyploidization opens new avenues to this area of research.

Comparative mapping between Arabidopsis thaliana and Brassica nigra indicates that Brassica genomes have evolved through extensive genome replication accompanied by chromosome fusions and frequent rearrangements.

The data support that modern diploid Brassica species are descended from a hexaploid ancestor, and that the A. thaliana genome is similar in structure and complexity to those of each of the hypothetical diploids progenitors of the proposed Hexaploids.

The analyses indicate that coalescent times for duplicated sequences fall into two distinct groups, corresponding to roughly 20.5 and 11.4 million years, which strongly discounts the possibility that the maize genome is the product of a genomic allotetraploid event, and also suggests that one of the two ancestral diploids shares a more recent common ancestor with sorghum than it does with the other ancestraldiploid.
