A novel plant DNA extraction method using filter paper-based 96-well spin plate.

Area of Science:

• Molecular Biology
• Plant Science
• Biotechnology

Background:

• High-throughput plant DNA extraction is crucial for molecular marker analysis.
• Commercial DNA extraction kits are often expensive, limiting accessibility for smaller laboratories.
• There is a need for cost-effective and safe DNA extraction methods.

Purpose of the Study:

• To develop a simple, low-cost, and safe method for high-throughput plant DNA extraction.
• To evaluate the efficacy of homemade filter paper-based spin plates for DNA binding.
• To demonstrate the utility of the extracted DNA in molecular marker analysis.

Main Methods:

• Preparation of 96-well spin plates using filter paper as a DNA-binding material.
• Utilization of homemade, non-toxic buffers for DNA extraction.
• Validation of DNA quality and quantity for downstream applications.
• Application in molecular marker analysis of segregating tomato populations.

Main Results:

• Filter paper was confirmed as an efficient solid-phase DNA binding material, comparable to commercial silicon-based filters.
• Plant DNA extracted using the homemade method was suitable as a template for Polymerase Chain Reaction (PCR).
• The method demonstrated efficacy in molecular marker analysis, particularly in segregating populations.

Conclusions:

• A simple, low-cost, and safe method for high-throughput plant DNA extraction was successfully developed.
• The homemade filter paper-based spin plate method offers a viable and economical alternative to commercial kits.
• This technique is particularly beneficial for laboratories with limited financial resources.
