Orchids belong to Orchidaceae which is one of the largest families in flowering plants. This family comprises over twenty thousand members, and many of them are fascinating with attractive flowers that sell in the markets with increasing demand around the world. What often receives less attention is the fact that some orchids are edible or scented, and more than this, many species have long been used in preparations in traditional medicine. The Special Issue "Orchid Biochemistry" collected original research and review articles that explore molecular aspects and insights into pigment formation, floral scent and pollination, bioactive compounds, plant-microbial interaction as well as biotechnology in orchid species.
