          Plant Testing

          The testing of DNA in plant tissues is an important process in various fields of agricultural research, including crop trait development and seed quality control. Scientists in the plant community need tools to address a range of issues including disease resistance, transgenic seed development, yield improvement, population genetics and plant physiology. Extraction of high-quality DNA from leaf, seed, root or other plant material is essential for reproducible DNA analysis by quantitative PCR, genotyping by sequencing (GBS) or next-generation sequencing (NGS) methods.

          Plant and Food DNA and RNA Extraction Protocols

          Promega DNA and RNA extraction products are used to purify nucleic acid from a wide variety of plant sample types. Our collection of plant and food application notes contains protocols and example data from many plant samples and includes example manual, automated and plate-based methods.

          Plant DNA Purification


          Unlike animal cells, plant cells have rigid cell walls made of tough fibrous material and contain compounds that can interfere with DNA isolation as well as downstream applications, such as PCR. This makes isolating DNA from plant tissue more challenging. The Maxwell? RSC Plant DNA Kit is one example solution based on paramagnetic cellulose particles that consistently isolates high yields of DNA from a broad range of plant types in a safe and efficient manner. High-throughput automation is also available to address large numbers of samples that are processed in 96-well or 384-well plates.

          GMO Testing


          The European Union (EU) and many other countries have policies for labeling or excluding products containing material from genetically modified organisms (GMO). GMO testing confirms the amount of GMO present in plants, seeds or foods and ensures compliance with EU and global regulations. PCR-based GMO detection methods are commonly used and rely on high yields of DNA with high purity for reproducible performance.
