Multilocus analysis of variation and speciation in the closely related species Arabidopsis halleri and A. lyrata.
Nucleotide variation in eight effectively unlinked genes was surveyed in species-wide samples of the closely related outbreeding species Arabidopsis halleri and A. lyrata ssp. petraea and in three of these genes in A. lyrata ssp. lyrata and A. thaliana. Significant genetic differentiation was observed more frequently in A. l. petraea than in A. halleri. Average estimates of nucleotide variation...
متن کاملPopulation genetic analysis of Pseudomonas aeruginosa using multilocus sequence typing.
To study the population genetic structure of Pseudomonas aeruginosa, we developed a multilocus sequence typing scheme. The sequences of internal fragments of seven housekeeping genes were obtained for 34 P. aeruginosa isolates from patients hospitalized in five different European cities. Twenty-six different allelic profiles were identified. The mean allelic diversity was 0.854 (range: 0.606-0....
متن کاملThe genetic basis of zinc tolerance in the metallophyte Arabidopsis halleri ssp. halleri (Brassicaceae): an analysis of quantitative trait loci.
The species Arabidopsis halleri, an emerging model for the study of heavy metal tolerance and accumulation in plants, has evolved a high level of constitutive zinc tolerance. Mapping of quantitative trait loci (QTL) was used to investigate the genetic architecture of zinc tolerance in this species. A first-generation backcross progeny of A. halleri ssp. halleri from a highly contaminated indust...
متن کاملForms of zinc accumulated in the hyperaccumulator Arabidopsis halleri.
The chemical forms of zinc (Zn) in the Zn-tolerant and hyperaccumulator Arabidopsis halleri and in the non-tolerant and nonaccumulator Arabidopsis lyrata subsp. petraea were determined at the molecular level by combining chemical analyses, extended x-ray absorption spectroscopy (EXAFS), synchrotron-based x-ray microfluorescence, and muEXAFS. Plants were grown in hydroponics with various Zn conc...
متن کاملThe allopolyploid Arabidopsis kamchatica originated from multiple individuals of Arabidopsis lyrata and Arabidopsis halleri.
Polyploidization, or genome duplication, has played a critical role in the diversification of animals, fungi and plants. Little is known about the population structure and multiple origins of polyploid species because of the difficulty in identifying multiple homeologous nuclear genes. The allotetraploid species Arabidopsis kamchatica is closely related to the model species Arabidopsis thaliana...
