Cysteine protease inhibitor (cystatin) genes exist in animals, plants and microorganisms. There are 12 cysteine protease inhibitors in rice (Oryzacystatin, OC) which associated with biotic/abiotic stresses responses and normal growth and development. Oryzacystatin belongs to pathogenesis-related gene family 6 (PR6), namely protease inhibitor class in rice genome. In this study, the domain architecture and subcellular localization of oryzacystatin was predicted, and transcription analysis was also carried out. Furthermore, oryzacystatin expression profiling was surveyed in different tissues during rice normal growth using western blot (WB) technology, most of the proteins were detected in late stage of rice growth but merely in the seedling stage.
