Chromosome Numbers for Some Erodium L'Hér (Geraniaceae) Species of Iran
Erodium (Geranaiceae) species are distributed in different habitats of Iran. Some species are of medicinal importance while some are well known weeds. There are no chromosome counts for Erdoium species of Iran. Chromosome numbers are given for six taxa of Erodium (Geraniaceae) from Iran: E. cicutarium (2n=36), E. ciconium(2n=18), E. malacoides (2n=20), E. moschatum (2n=20), E. neuradifolium (2n...
متن کاملMapping barley genes to chromosome arms by transcript profiling of wheat-barley ditelosomic chromosome addition lines.
Wheat-barley disomic and ditelosomic chromosome addition lines have been used as genetic tools for a range of applications since their development in the 1980s. In the present study, we used the Affymetrix Barley1 GeneChip for comparative transcript analysis of the barley cultivar Betzes, the wheat cultivar Chinese Spring, and Chinese Spring - Betzes ditelosomic chromosome addition lines to phy...
متن کاملThe Wild Numbers
This paper studies the integers that belong the multiplicative semigroup W generated by { 2n+1 : n ≥ 0} and 1 2 . They form a multiplicative semigroup W(Z) of integers which we call the wild integer semigroup, and the wild numbers are the generators of W(Z). It presents convincing evidence that the wild numbers consist of all prime numbers excluding 3.
متن کاملWild and Wooley Numbers
That is, W0 is the set of all finite products of the generators, allowing repetitions. Let W signify the larger multiplicative semigroup generated by W0 together with {1/2}. We call W the wild semigroup and W0 the Wooley semigroup. The question we consider is: Which integers belong to these semigroups? The sets of integer elements W(Z) := W ∩ Z and W0(Z) := W0 ∩ Z themselves form multiplicative...
متن کاملChromosome-Numbers in Bromeliaceae
Eighty-three chromosome counts are reported for 72 taxa of the Bromeliaceae. Fifty-eight of these counts are the first known chromosome number reports for their respective taxa. A model of chromosomal evolution in the Bromeliaceae (n = 25) is presented. The model is parsimonious and consistent with existing data on meiotic chromosome numbers within the family and in the closely related Vellozia...
