Název v původním jazyce
Preparation of HMW DNA from plant nuclei and chromosomes isolated from root tips.
Popis výsledku v původním jazyce
Simple, fast and cost-effective method for preparation of DNA with high molecular weight (HMW DNA) from plant nuclei and mitotic chromosomes has been developed. The technique involves mechanical homogenization of formaldehyde-fixed root tips, purification of nuclei and/or chromosomes on sucrose gradient, embedding in low-melting-point agarose, and DNA isolation in agarose plugs. Alternatively, nuclei and chromosomes may be purified using flow cytometry. Majority of DNA obtained is megabase-sized and well digestible by restriction endonucleases. The method is highly efficient as microgram amounts of DNA can be obtained from only several milligrams of plant tissue. Handling negligible amounts of plant material reduces the consumption of chemicals. Furthermore, the use of root tips makes it possible to obtain high-quality DNA even from plant species with leaves that are rigid or rich in secondary metabolites such as polyphenols. It is expected that preparation of HMW DNA from root tip nuc
