Abstract: A cDNA expression library from the flower bud of Dendrobium nobile was constructed into pcDNA3.0 eukaryotical expression plasmid used SMARTTM cDNA library construction protocol. The result showed that the cDNA expression library contained 3.02 ×105 pfu, the size of the inserts ranges from 0.5 kb
to 2.5 kb, and the percentage of positive clones was almost 100%. All of the above mentioned have answered for the general requirements of a cDNA library. This provides a base for cloning of important genes related to
flower bud differentiation in Dendrobium nobile.

Key words: Dendrobium nobile, Flower bud, cDNA expression library
