英文摘要：

OBJECTIVE To review the current progress in molecular biology research of Dendrobium officinale. METHODS Relevant literatures were reviewed and analyzed. RESULTS The molecular biology research of D. officinale mainly include three aspects ： application of modern molecular maker technique in D. officinale authentication, genetic diversity and phylogenetic analysis of D. officinale and the closely related Dendrobium species, and construction of cDNA library followed by gene clone study for the sake of dissecting plant growth and metabolism regulation mechanism. CONCLUSION Great achievements have been made on molecular biology research of D. officinale. The findings will be useful for further elucidation of the plant growth and development, metabolic regulation, along with the appropriate exploration, utilization, and conservation of D. officinale germplasm.
