An efficient and simple CTAB based method for total genomic DNA isolation from low amounts of aquatic plants leaves with a high level of secondary metabolites

Authors

Abstract:

An efficient DNA isolation protocol specifically modified to get pure quality DNA required for molecular studieshas been reported in this paper. Some aquatic plants (Potamogeton spp., Ceratophyllum demersum and Myriophyllum spicatum) were used for the study. The protocol developed will be useful in getting high and pure DNA. Instead of using the available DNA extraction kits, this protocol can be used to get pure quality DNA, freefrom proteins and polysaccharide compounds. The absorbance rate A260/A280 was 1.92 ± 0.069 and A260/A230 was 1.73 by spectrophotometer and NanoDrop machines which showed the sample genomic DNA is pure, free from contaminant proteins and polyphenolics/polysaccharides compound. The highest concentration of DNA was 640 ± 340.58 ng/μl when measured at 260 nm. When we run on agarose gel also, the isolated DNA gave a clear and sharp band. Thus, the DNA does not need any additional purification before proceeding for molecular analysis of the isolated DNA samples. This protocol is very simple and economical which will find wide applications in genomic studies of aquatic plants.

A simple and efficient DNA extraction protocol for old herbarium leaves of Bellevalia (Asparagaceae, Scilloideae)

High-quality DNA extraction plays an important role to make sharp bands in the gel electrophoresis and also produces clean chromatograms. Usually, DNA extract is delivered using the modified CTAB method but this method cannot obtain high-quality DNA for molecular analysis from old dried leaves of Bellevalia due to having different chemical compounds which inhibit to obtain a clear DNA extractio...

A Simple and Rapid Leaf Genomic DNA Extraction Method for Polymerase Chain Reaction Analysis

In plants, secondary metabolites and polysaccharides interfere with genomic isolation procedures and downstream reactions such as restriction enzyme analysis and gene amplification. The removal of such contaminants needs complicated and time-consuming protocols. In this study, a simple, rapid and efficient method for leaf DNA extraction was optimized. This method use small amount of plant mater...

Phenol-stacked carbon nanotubes: A new approach to genomic DNA isolation from plants

Extraction of intact quality DNA from plant tissues, especially those rich in secondary metabolites, is often challenging. Literally, hundreds of different DNA isolation protocols from various plant species have been published over the last decades. Although many commercial DNA isolation kits are convenient and designed to be safe, their cost and availability cause limitations in small molecula...

An efficient method for isolation of RNA and DNA from plants containing polyphenolics.

Isolation of high quality RNA and DNA from plants especially cotton (Gossypium hirsutum; family Malvaceae) is notoriously difficult. This problem has been attributed to high content of phenolic terpenoids and tannins present in cotton cells (Katterman, and Shattuck, 1983). These compounds bind to RNA and DNA upon cell lysis and cannot be removed by conventional extraction procedures. Such RNA i...
