Genome size diversity of some species of Cephalanthera from Iran

摘要: AbstractKnowledge of genome size is used in a wide variety biological fields such as cell and molecular biology, ecology, phytogeography, systematics, development sequencing projects for comparative studies structure evolution key diversity characters. Orchidaceae the most variable angiosperm family, with 168-fold differences size. This research was begun because lack DNA content data from genus terrestrial orchids, Cephalanthera, Iran. To estimate nuclear (2C value) three species flow cytometric study conducted young well-developed leaves plants collected their natural habitats Gilan Mazandaran provinces The 2C ranged 27.49 pg C. rubra to 35.39 pg caucasica 36.33 pg longifolia, using propidium iodide staining method Pisum sativum “Ctirad” DNA = 9.09 pg) reference standard. Coefficients variatio...
