In this study, chromosome length, karyomorphology and asymmetry of six Turkish Muscari species; muglaensis, M. nazimiyensis, pallens, pamiryigidii, inundatum fatmaceranie were evaluated. The somatic number all examined taxa was determined as 2n=18. basic x=9. Chromosomes consist metacentric, submetacentric, subtelocentric chromosomes. This is the first report on morphology for five studied. Stu...

The wild-relative gene pools of wheat are a rich source of genetic variation for wheat improvement.Karyotypes of eight genotypes of Triticum monococcum subsp. aegilopoides and eight genotypes of Aegilops cylindrica,which grown wild next to each other in different regions in the west of Iran were studied. Root tips were treated in α-bromonaphthalene solution, fixed in chromic acid-formaldehyde f...

The aim of this paper was to present the second case B chromosomes in Auchenipteridae (Trachelyopterus sp.), and test hypothesis that species Parauchenipterus galeatus might have a common origin, since these two phylogenetic proximity. Both 58 A complement, heterochromatin preferentially located at terminal region most chromosomes, simple Ag-NORs short arm subtelocentric pair, which confirmed b...

Trifolium species and cultivars are considered important forage crops iran , growing throughout the country. The present article considered the karyotypic details of Trvulim taxa using multivariate statistical analysis. Taxa studied included: Trifolim restylinatum (six populations: Shazand, Soriyan, Kordestan, Harati, Enaj and Lordegan), T. repense, T, fragverm, T. prateme and T, alexandrin...

the chromosome number and type as well as karyotype in vimba vimba persa were studied. a total of 200 larvae and 10 fingerlings of this species with an average weight of 30.2g obtained from shahid ansari fish hatchery. to arrest mitosis in metaphase, larvae under study were placed in a 0.05% solution of colchicine for a period of 6h while the fingerlings were given an intramuscular injection of...

introduction: heterochromatin consists of dna sequences that are not transcribed, and are repeated in short tandem at heterochromatic regions of chromosomes 1, 9, 16 as well as the distal part of long arm of chromosome y. slightly large tandem repeats at the centromeres of human chromosomes are also considered as heterochromatin regions. the main aim of the present study is to evaluate the hete...
