| Cymbidium sinense, The Orchidaceae family is
economically and ecologically important, comprising approximately 10% of all seed plant
species. Cymbidium sinense has a long cultural history over many centuries. It was named the
black orchid in 'Jin Zhang Lan Pu', the earliest work on orchids published in AD1233. The
species bears attractive, dark green foliage and elegant flower spikes with many strongly
scented flowers. Cymbidium sinense (C. sinense) is noted for the abundant variation in
flower patterning, flower color, and leaf color. More than 1000 natural variations have been
derived from C. sinense, which makes it an ideal species to study the evolution of
phenotypic traits in orchids. Most previous studies on C. sinense have focused on
traditional biology such as embryology, physiology, genetic diversity and population
structure. Recent research involves micropropagation, chemical variation in essential oils
and the unigenes associated with flower development, leaf color variation and the origin of
pelorism. Here, we provide genome sequencing data for C. sinense. The high-quality
chromosome-scale genome assembly was 3.52Gb in size, 29638 protein-coding genes were
predicted. Those genome sequencing data will assist in investigation of the flowering
pathway and various other biological mechanisms in other orchid species.
