     Orchids, constituting approximately 10% of all seed plant species, have enormous value for commercial horticulture, and are of specific scientific interest because of their spectacular flowers, ecological adaptations and secondary metabolites. Dendrobium is the third largest genus of Orchidaceae and contains approximately 1,450 species, characterised by a fleshy stem with abundant polysaccharides and growing in diverse habitats. A draft genome sequence of Dendrobium officinale Kimura & Migo has been reported before but the highly fragmented assembly and the presence of multiple peaks in K-mer analyses, suggesting that its sequence is likely derived from an artificial hybrid, seriously complicate correct interpretation of the genome. To complement the lack of a high quality, well assembled genome sequence for Dendrobium, we here present the genome of D. catenatum Lindl., a lithophytic orchid found in subtropical and temperate regions and commonly used as a health food in many Asian countries. Analysis of the D. catenatum genome sequence offers insights into flower development and polysaccharide synthesis, as well as its wide distribution. “The Dendrobium catenatum Lindl. genome sequence provides insights into polysaccharide synthase, floral development and adaptive evolution”.
