The RP-HPLC based comparative quantification of some important redox sensitive phenolic acids and flavonoids revealed overall greater elicitation of chalcone synthase related flavonoid biosynthetic pathway, concomitant with the greater utilization of cinnamic acid for the seedlings of the salinity resistant rice cultivar Patnai as compared to susceptible cultivar IR29 grown under post imbibitional salinity stress (PISS). When compared, the cultivar Patnai further exhibited significantly better antioxidant-coupled redox-regulation by up regulating ascorbate–glutathione pathway and reducing the expression of oxidative deterioration under PISS as compared to its counterpart, the cultivar IR29. A model for redox homeostasis in which complementation of action of ROS scavenging secondary metabolites with enzymatic antioxidant defense at metabolic interface necessary for maintenance of the redox homeostasis to combat salinity stress has been proposed.

ROS清除次生代谢物与酶促抗氧化防御系统的互补增强了水稻在盐胁迫下的氧化还原调节特性。

基于 RP-HPLC 的一些重要氧化还原敏感酚酸和黄酮类化合物的比较定量显示，与易感性水稻品种相比，与易感性水稻品种 Patnai 相比，更多地利用了肉桂酸用于幼苗的查耳酮合酶相关类黄酮生物合成途径。在后吸水盐度胁迫 (PISS) 下生长的品种 IR29。相比之下，与其对应物品种 IR29 相比，品种 Patnai 通过上调抗坏血酸 - 谷胱甘肽途径并减少 PISS 下氧化恶化的表达，进一步表现出明显更好的抗氧化偶联氧化还原调节。
