 The expression analysis revealed that OsAPx4 gene present higher expression in leaves, but also is expressed in roots and panicles of rice.Analysis of the OsAPx4 promoter revealed expression in leaves, vascular button and panicle, mainly in the conducting vessels. In situ hybridization experiments in panicles showed expression in lemma and peduncle[3].Expression of the gene OsAPX4, coding for ascorbate peroxidase in leaves and roots of rice were induced by abiotic stresses, such as NaCl, NaHCO3 and Na2CO3, polyethylene glycol (PEG) 6000, H2O2, CuCl2[4]. Expression of OsAPX4 gene in yeast can enhance the resistance to salts(NaCl, NaHCO3). Trans-genic Arabidopsis over-expressing the OsAPX4gene also exhibited  growth  advantage  under  NaCl  and  NaHCO3 stress environments. These examinations imply that the OsAPX4 gene plays an important role in the response of plants to several environmental stress conditions[4].

 Plants use antioxidant enzymes such as superoxide dismutase (SOD), ascorbate peroxidase (APx), glutathione reductase (GR), and catalase (CAT)as well as antioxidants catalase (AsA) and glutathione (GSH) to scavenge ROS[1]. The involvement of  H2O2 in HS- and Cd-mediated changes in the expression of  APx and GR in leaves of rice Seedlings has been reported. APx plays an important role in scavenging and in protecting cells against the toxic effects of H2O2 in higher plants. APx is located in different cellular compartments. Eight types of APx in rice have been described for Oryza sativa: two cytosolic (OsAPx1 and OsAPx2), two putative peroxi-somal (OsAPx3 and OsAPx4), and four chloroplastic isoforms (OsAPx5, OsAPx6, OsAPx7, and OsAPx8)[2]. OsAPx4 gene has its function related to the functions assigned to the peroxisome and probably acts in the physiological processes regulation, such as senescence[3].
