title: degradome-seq of Jatropha curcas
design: The Jatropha curcas seedlings were treated by12 C chill-hardening at 6h,12h, 24h, 48h, then chill-hardening 48h subsequent 1C chilling stress 1d, 2d, 3d, 4d, 5d(CH); another part which non-hardening and 1C chilling stress 1d, 2d, 3d, 4d, 5d(NH), 26/20C 0d, 2d, 7d as control(CK), were sampled seedlings leaves for degradome sequencing.
