Molecular markers are stretches of DNA that are located within the entire genome of a plant you can use the markers for medicinal plant authentication. DNA markers are not tissue-specific and thus can be detected at any stage of plant development. You can use molecular markers such as SCAR (Sequence Characterized Amplified Regions), LAMP (Loop Mediated Isothermal Amplification), SSRs (Simple Sequence Repeats), and SNPs (Single Nucleotide Polymorphisms) for the identification of medicinal plants.
