Application of Molecular Biology Techniques in Plant Identification

In plant taxonomy research, traditional identification methods mainly rely on the observation and comparison of morphological and ecological characteristics. However, this method appears inadequate when faced with issues such as significant morphological variation and difficulty in distinguishing closely related species. Conducting plant molecular identification is necessary to improve identification accuracy, address issues related to closely related and hidden species, protect biodiversity, promote agricultural and forestry development, and advance scientific research. This article mainly discusses the application of molecular biology techniques in plant identification, covering the importance, challenges, and specific applications and advantages of various molecular biology techniques in plant identification. This article elaborates on the importance of plant identification, the advantages of molecular biology technology, PCR based plant species identification, the application of DNA barcode technology in plant species identification, and the advantages of DNA barcode technology in plant identification. It introduces the application of PCR technology, DNA barcode technology, and other technologies in plant identification, and looks forward to future technological development directions.
