title: Ziziphus nummularia transcriptome under drought stress
design: After one month fifteen (three for each hour of treatment)seedlings were subjected to 30% Polyehylene glycol M.W. 6000 (PEG 6000) for different time periods 6 h, 12 h, 24 h, 48 h and 72 h, respectively to stimulate drought stress at -1.25 Mpa (osmotic potential) and three control seedlings were harvested without PEG6000 treatment for further downstream processing.
