title: miRNA-Seq of Jatropha curcas
design: The Jatropha curcas seedlings were treated by12 chill-hardening at 6h,12h, 24h, 48h, then chill-hardening 48h subsequent 1 chilling stress 1d, 2d, 3d, 4d, 5d, another part which non-hardening and 1 chilling stress 1d, 2d, 3d, 4d, 5d, 26/20 0d, 2d, 7d as control, were sampled seedlings leaves for miRNAome sequencing (three biological replicates).
