Development of Rapid and Less Hazardous Plant DNA Extraction Protocol using Potassium Phosphate Buffer

Area of Science:

• Molecular Biology
• Plant Science
• Biotechnology

Background:

• Traditional plant DNA extraction methods are time-consuming and use hazardous reagents.
• These limitations hinder application in resource-limited laboratories and high-throughput analyses.
• Development of efficient and safer protocols is crucial for plant research.

Purpose of the Study:

• To develop a rapid, less hazardous, and cost-effective plant DNA extraction protocol.
• To utilize potassium phosphate buffer for an improved DNA extraction process.
• To provide a viable alternative for laboratories with limited resources.

Main Methods:

• Genomic DNA was extracted from chili pepper (Capsicum annuum) using a novel potassium phosphate buffer protocol.
• The new method was compared against CTAB-based, mini-prep, and commercial kit protocols.
• DNA quality, quantity, practicality, and cost per reaction were evaluated.

Main Results:

• The potassium phosphate buffer protocol yielded DNA of comparable quality and adequate concentration for downstream applications like PCR and sequencing.
• This method involves only 5 main steps, making it simple and rapid.
• The protocol uses only ethanol, is less hazardous, low-cost, and suitable for resource-limited settings.

Conclusions:

• The developed potassium phosphate buffer protocol is a promising alternative for plant DNA extraction.
• It is applicable for both large-scale analyses and diverse laboratory settings.
• Further research is recommended to assess its efficacy across various plant species.
