Karyological Investigations of Selected Angiosperms from Georgia and Azerbaijan
Chromosome numbers of eleven angiosperm species, five dicots and six monocots from Georgia and Azerbaijan are reported. The chromosome number of Cruciata coronata (Rubiaceae) is provided for the first time (2n = 22). Additionally, karyotypes are presented for five species, those of Danae racemosa (Ruscaceae), Paris incompleta (Trilliaceae), and Ruscus hyrcanus (Ruscaceae) for the first time. Th...
متن کاملComparison of Molecular and Karyological Data
A karyological study and the analysis of two mitochondrial genes were conducted in several species of cordyliformes from Madagascar. Both studies confirmed the monophyly of cordyliformes. The karyological conservatism and small genetic distance among mitochondrial genes observed in these species are in line with the hypothesis that all cordyliformes should be included in a single family. The tw...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اول[Karyological study of some Corvine birds (Corvidae, aves)].
Karyotypes were studied in the hooded and carrion crows, their naturally occurred hybrids, the jungle crow, the azure-winged magpie (2n = 80 in all aforementioned birds), and the magpie (2n = 82). Corvine birds of Primorskii Krai were karyotyped for the first time. In addition to the similarity in the diploid chromosome sets, corvine birds were shown to have a similar structure of karyotype: in...
متن کاملChromosomes of some argentine angiosperms and their taxo - nomic
Meiotic or mitotic chromosomes of eleven species of angiosperms native in Argentina, belonging to seven families, were studied in order to be used in cytotaxonomic studies and gain some insights on the evolutive relationships of the different groups. Most of our data were the first cytological information for the species. The genus Alvaradoa Liebm. was investigated cytologically for the first t...
