项目摘要

Export of reducing equivalents from chloroplasts is necessary to prevent photoinhibition and to supply reducing power to cytosolic nitrate reductase. The transport process is mediated by malate valve comprising 2-oxoglutarate/malate transporter (OMT) and malate dehydrogenase (MDH) isozymes. We produced Arabidopsistransformants overexpressing OMT and stromal NADP-MDH, and found that the tolerance to environmental stresses and the ability of nitrate assimilation are improved in the transformants. Therefore, malate valve would be a new target to improve environmental tolerance and nitrogen metabolism of crops.
为了防止抑制光抑制并为胞质硝酸盐还原酶提供还原的功率,必须从叶绿体中出口相同。运输过程是由包含2-氧气/苹果酸转运蛋白(OMT)和苹果酸脱氢酶(MDH)同工酶的苹果酸瓣介导的。我们产生了过表达OMT和基质NADP-MDH的拟南芥,并发现对环境应力的耐受性和硝酸盐同化的能力在转化体中得到了提高。因此,苹果酸阀将是提高农作物的环境耐受性和氮代谢的新目标。
