Taking the leaves and young stems as material, a normalized full-length eDNA library of Ceratoides lanata was constructed. The seedlings of potted Ceratoides lanata were treated by gradient cold stress, normalized fulllength eDNA library was successfully constructed by DSN （duplex-specific nulease）-normalization combined with SMARTTM （switching mechanism at 5＇end of RNA transcript） technique. The results show that the capacity of the primary library was 1.4×10^6pfu. The PCR results show that the insertion size was between 0. 5 kb and 3. 0...
