Corrected Chromosome Number for Spartina in Ireland

Chromosome Number Variation in Iranian Populations of Acorus calamus

Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...

Karyotype analysis and new chromosome number reports for nine Vicia species in Iran

This study concerns diploid chromosome numbers and karyotype analysis of nine species belonging to four sections (Vicilla, Cracca, Variegata and Anatropostylia) of the subgenus Vicilla of the genus Vicia (Fabaceae). The chromosome numbers of Vicia alpestris subsp. hypoleuca, V. aucheri, V. ciceroideae, V. gariensis, V. iranica, V. koeieana, V. rechingeri, V. sojakii and V. venulosa are reported...

A Y-chromosome signature of hegemony in Gaelic Ireland.

Seventeen-marker simple tandem repeat genetic analysis of Irish Y chromosomes reveals a previously unnoted modal haplotype that peaks in frequency in the northwestern part of the island. It shows a significant association with surnames purported to have descended from the most important and enduring dynasty of early medieval Ireland, the Ui Neill. This suggests that such phylogenetic predominan...

Mechanisms of Chromosome Number Evolution in Yeast

The whole-genome duplication (WGD) that occurred during yeast evolution changed the basal number of chromosomes from 8 to 16. However, the number of chromosomes in post-WGD species now ranges between 10 and 16, and the number in non-WGD species (Zygosaccharomyces, Kluyveromyces, Lachancea, and Ashbya) ranges between 6 and 8. To study the mechanism by which chromosome number changes, we traced t...
