Function
Little is known about the individual functions of the APX isozymes in rice, partly because of the difficulty in obtaining sufficient amounts of homogeneous and active isozymes for analysis[1].
Expression
RNA gel blot analysis showed that the transcription of the OsAPx2 gene increased significantly with time of exposure to NaCl, NaHCO3, and PEG 6000[1]. APX isozymes occur in several cell compartments and occur in many plants, including Arabidopsis, spinach, pumpkin, tobacco, soybean, potato and rice. Plant APX isoforms act differently in response to stress and in different developmental stages[2]. rice plants that overexpress OsAPXa and have increased APX activity. The effect of increased APX activity on the levels of H(2)O(2) and lipid peroxidation were determined by measuring H(2)O(2) levels and malondialdehyde (MDA) contents in spikelets during cold treatments at the booting stage. The levels of H(2)O(2) and the MDA content increased by 1.5-fold and twofold, respectively in WT plants subjected to a 12 °C treatment for 6 days. In contrast, transgenic lines showed small changes in H(2)O(2) levels and MDA content under cold stress, and H(2)O(2) levels and MDA content were significantly lower than in WT plants. APX activity showed negative correlations with levels of H(2)O(2) and MDA content, which increased during cold treatment. Cold tolerance at the booting stage in transgenic lines and WT plants was evaluated. Spikelet fertility was significantly higher in transgenic lines than in WT plants after a 12 °C treatment for 6 days. These results indicate that higher APX activity enhances H(2)O(2)-scavenging capacity and protects spikelets from lipid peroxidation, thereby increasing spikelet fertility under cold stress[3].
