TAILIEUCHUNG - Review on molecular markers for identification of Orchids

Orchidaceae is one of the most valuable plant groups all over the world, and is also an impressively large and complex family of flowering plants. Effective molecular tools used for the identification of orchid species should be developed to support traditional morphological approaches. This study reviews most of the DNA fragments that have been used as taxon identifiers in researches conducted on Orchidaceae in order to assess potential molecular markers and metric measurements for the identification of orchid species. | LIFE SCIENCES BIOTECHNOLOGY Review on molecular markers for identification of Orchids Thi Huyen Trang Vu1 Thi Ly Le2 Truong Khoa Nguyen3 Duy Duong Tran3 Hoang Dung Tran4 1School of Agricultural Science and Biotechnology Nguyen Tat Thanh University 2School of Biotechnology Ho Chi Minh International University 3Genetic Engineering Division Institute of Agricultural Genetics 4Nguyen Tat Thanh University Received 1 March 2017 accepted 2 June 2017 Abstract Orchidaceae is one of the most valuable plant groups all over the world and is also an impressively large and complex family of flowering plants.

Classification number Introduction Orchidaceae is one of the largest and most complex families of flowering plants comprising of approximately 22 500 species belong to 736 currently recognised genera 1 . Orchids have many values ranging from the beauty of their flowers to therapeutic properties in some species. However taxons of Orchidaceae are endangered this is mainly because of over-collection and habitat destruction and all species are included in Conventions on International Trade of Endangered Species of Fauna and Flora CITES I and II 2 . Illegal trade and imitations have also become increasing problems. Unfortunately laws banning these issues and their enforcement have met obstacles mostly due to the imperceptible difference of species morphology. So it is very difficult to identify orchid species and their inter-species hybrids using traditional classification even .
