“…coleopoda and A. haussknechtii, are the first reports and our count confirm prior reports of An. tinctoria (Nagl andEhrendorfer 1974, Van Loon 1982 and others) and confirms some previous reports for Anthemis altissima (Kuzmanov et al 1977, Stephanov 1982, Oberprieler 1998.…”

Summary Seventeen chromosome counts of 15 taxa (15 species) in the tribe Anthemideae of the family Astraceae are reported. All taxa were collected from Zanjan, Iran. Six counts are new reports (including Achillea talagonica, Anthemis coleopoda, Anthemis haussknechtii, Tanacetum pinnatum, Tanacetum polycephalum, and Tanacetum kotschyii), four are not accordance with previous counts (or are new reports for ploidy levels) and reminders are confirmation of very limited (one to six records) previous data. All of studied taxa have the basic number xϭ9, with ploidy levels ranging from 2ϫ to 10ϫ.

“…This is the third study carried on Artemisia genome size by our research team (see Garcia et al 2004, for previous results), but the first focused on intraspecific variation and plant domestication within one species. Previously, other works on genome size reported C-values for seven Artemisia species (Nagl and Ehrendorfer 1974;Geber and Hasibeder 1980;Greilhuber 1988;Bennett and Smith 1991). According to the categories of genome size (Soltis et al 2003), the species reported in this study should be considered as intermediate (<3.5 pg to 14.0 pg).…”

Different wild Mediterranean populations of Artemisia arborescens from diverse locations, representing its geographical distribution, as well as some of its well-known cultivars and some specimens cultivated as omamentals in gardens, streets, roads and nurseries, were analysed for genome size estimation. Other closely related species endemic to Macaronesia, A. canariensis, A. argentea and A. gorgonum, were also measured, and their nuclear DNA amount has been related to the biogeography of this group of species. Additionally, five populations of the closely related A. absinthium were analysed to establish comparisons. Measurements, acquired by flow cytometry, ranged from 8.29 pg to 11.61 pg for 2C values. Statistically significant differences of nuclear DNA amounts with respect to factors such as insularity or domestication have been detected. However, a quite low intraspecific genome size variation has been detected in these species. Furthermore, the study also addressed the possible hybrid origins, and possible misidentifications of some of the supposed cultivars ofA. arborescens..

“…It has been proposed that, within a genus, an increase in nuclear DNA content implies a longer cell cycle, thus annual plants usually have lower DNA amounts than perennial ones (Rees and Narayan 1981). Nagl and Ehrendorfer (1974) reported this tendency in some members of the tribe Anthemideae, including two (one annual and one perennial) Artemisia species. This is now confirmed, in this genus, by the annual species A. scoparia which shows the lowest TKL amounts of all the present populations, its TKL value is lower than that of the perennial species and TKL strongly correlated with genome size and DNA content.…”

Chromosomal Evolution in Some Iranian Artemisia L. using Numerical Analysis of Karyotypes

2009

Summary A karyological study of seven taxa (four sections) of genus Artemisia L. from Azerbaijan region (Iran) is presented. We found the two usual basic numbers in the genus xϭ9, the most common one (in three diploid and two tetraploid populations) and xϭ8 (in two diploid populations).The intra-(A1) and interchromosomal (A2) asymmetry index, which does not depend on chromosome number or chromosome size showed asymmetry index based on A1 value has indicated that the chromosomes in some Iranian Artemisia evolved in order of section Absinthium and Artemisia meanwhile section Seriphidium and Dracunculus are close to each other but they can separate from Section Absinthium and Artemisia.
