Chromosome numbers and karyotype features of Phlomis olivieri Benth. (Lamiaceae) from Iran

Karyotype and Sex-Chromosome Polymorphism in Nesokia indica, from Iran

Phytochemical constituents, antioxidant activity and toxicity potential of Phlomis olivieri Benth.

Background and objectives: Phlomis olivieri Benth. (Lamiaceae) is a medicinal plant widely distributed in Iran. In the present study, we have investigated the phytochemical constituents, antioxidant activity and general toxicity potential of the aerial parts of this species. Methods: Silica gel (normal and reversed phases) and Sephadex LH-20 colu...

بررسی آناتومی، گرده‌شناسی و انواع کُرک گونه Phlomis olivieri از تیره Lamiaceae

در مطالعه حاضر، صفات آناتومی، گرده‌شناختی و انواع کُرک گونه Phlomis olivieri به منظور شناخت آنها جهت به‌کارگیری در اهداف سیستماتیک بررسی شد. نتایج نشان داد که دستجات آوندی در ساقه در کنار هم قرار دارند. مزوفیل از یک لایه پارانشیم نرده‌ای و سه تا چهار لایه پارانشیم اسفنجی تشکیل شده است. دو دسته آوند همجوار در مرکز و دو دسته آوند فرعی کوچک در حاشیه دمبرگ و چهار دسته آوند کوچک در برگک وجود دارد. پن...

Chromosome Numbers and Karyotypes of Four Species Rubus L. from North of Iran

Karyotype study was performed across 7 populations of 4 Rubus species growing in Iran. The results showed that the chromosome numbers of R. sanctus (2n=2x=14) diploid, R. caesius, and R. discolor were (2n=4x=28) tetraploids, R. persicus (2n=8x=56) octoploid. The chromosome numbers of R. discolor, and R. persicus were reported here for the first time. Karyotypic formula also varied between the s...

Genome Size Estimates and Chromosome Numbers of Callicarpa L. (Lamiaceae)

Genome size estimates and chromosome number information can be useful for studying the evolution or taxonomy of a group and also can be useful for plant breeders in predicting cross-compatibility. Callicarpa L. is a group of ’140 species with nearly worldwide distribution. There are no estimates of genome size in the literature and the information on chromosome numbers is limited. Genome size e...
