Karyological Studies of <i>Fritillaria</i> (Liliaceae) Species from Iran

Karyological studies in Brazilian species of Lippia L. (Verbenaceae).

The genus Lippia (Verbenaceae) comprise around 160 species spread out mainly in South and Central Americas with few African species, some of them with potential medicinal use. Brazil is one the most important centers of diversity with approximately 75% of the species described so far. Innumerous species are endemic and poorly studied especially at a cytological level. Here, chromosomal length, ...

Karyological and meiotic studies in seven species of Coreinae (Hemiptera: Heteroptera: Coreidae) from North India.

Coreinae, the largest subfamily of Coreidae, is distributed worldwide but is most abundant in the tropics. Cytogenetic data is available for 122 species, which include 40 from India. In the present paper, 7 species of Coreinae have been cytogenetically investigated for the first time for their diploid chromosome complement and for meiosis. Also, this is the first cytogenetic report for the gene...

Karyological studies in Jaborosa (Solanaceae)

Sixteen species of Jaborosa (Solanaceae), including eight endemic to Argentina, were studied karyologically. The numbers n = 12 and/or 2n = 24 were found in all species, the majority of the cases being new reports. Mitotic chromosomes were smallto medium-sized, the average length varying from 2.95 to 4.93 mm. All species had one to three chromosome pairs with satellites. The karyotypes, obtaine...

Karyological studies in Triticum monococcum subsp. aegilopoides and Aegilops cylindrica species grown wild pairwise in west Iran

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...
