In order to study the effect of expression pattern of high hydrostatic pressure on high plant, a SSH-cDNA library was constructed with rice germinating seeds in this paper. Suppression subtractive hybridization (SSH) in combination with mirror orientation selection (MOS) was performed using the mRNA from rice germinating seeds treated by 75 MPa high hydrostatic pressure as tester and the mRNA from control (seeds untreated by high hydrostatic pressure) as the driver. 580 recombinant clones were picked through blue/white screening. PCR detection of the recombinant clones showed that the size of inserts mainly ranged from 200 bp to 1 000 bp, and the average size of these inserts were about 575 bp. Among the 580 recombinant clones, 542 clones (93.3%) were identified to be effective single band ones. After sequencing some of the recombinant clones, it was found that the genes induced by high hydrostatic pressure were mainly involved in metabolism, stress response and transcriptional regulation. The research paved the way for studying the gene expression patterns of rice seeds responding to high hydrostatic pressure.
