Abstract An experiment was conducted to explore the silver-nanoparticles (Ag-NPs) and abscisic acid (ABA) to elicit sub1A quantitative trait loci (QTL) responses under submergence stress. Rice genotypes cv. Swarna and Swarna Sub1 were pre-treated with 100 mg ml−1Ag-NP [Ag-NP(+)] and 10 μM ABA [ABA(+)] at 7-day-old seedlings for 1 day in two separate sets and subsequent transfer to complete submergence for 5 days. sub1A QTL regulatory APETALA2/ETHYLENE RESPONSE FACTOR (AP2/ERF) expression was mitigated for both genotypes under submergence; however, retrieved with Ag-NP(+) and ABA(+) variably. ABA(+) had recorded affirmative responses than Ag-NP(+) in net assimilation rate, relative growth rate, chlorophyll content, and metal accumulation under stress. cv. Swarna Sub1 under submergence had better recovery of proline and relative water content than others. Phenolics, flavonoids, carotenoids, and lycopene content were more influenced by ABA(+) than Ag-NP(+) to recover under submergence. The development of superoxide and hydrogen peroxide had a positive and fair correlation with nicotinamide adenine dinucleotide phosphate oxidase (EC 1.6.3.1) activity under submergence. cv. Swarna Sub1 responded better under submergence through invertase (EC 3.2.1.26), starch phosphorylase (EC 2.4.1.1) and sucrose synthase (EC 2.4.1.13) activity more with ABA(+) than Ag-NP(+). The functioning of sub1A QTL for anaerobic metabolism was improved in cv. Swarna Sub1 than cv. Swarna with the support of polymorphic expression of alcohol dehydrogenase (EC 1.1.1.1). Finally, given results may arise the prospect for mitigation submergence stress by Ag-NP(+) and ABA(+) through modulation of cellular responses affiliated to sub1A QTL.

银纳米颗粒和脱落酸调节亚 1A 数量性状基因座对水稻的耐淹性起作用（Oryza sativa L.）

摘要 进行了一项实验，探索银纳米颗粒（Ag-NPs）和脱落酸（ABA）在淹没胁迫下引发sub1A数量性状位点（QTL）响应。水稻基因型 cv. Swarna 和 Swarna Sub1 用 100 mg ml−1Ag-NP [Ag-NP(+)] 和 10 μM ABA [ABA(+)] 在 7 天大的幼苗中分两组预处理 1 天，随后转移至完全淹没 5 天。sub1A QTL 调节性 APETALA2/ETHYLENE RESPONSE FACTOR (AP2/ERF) 表达在淹没下两种基因型均减弱；然而，用 Ag-NP(+) 和 ABA(+) 不同地检索。ABA(+) 在净同化率、相对生长率、叶绿素含量和胁迫下的金属积累方面记录了比 Ag-NP(+) 的肯定反应。简历。Swarna Sub1在淹没下的脯氨酸和相对含水量的恢复比其他的好。酚类、黄酮类、类胡萝卜素和番茄红素含量受 ABA(+) 的影响比 Ag-NP(+) 更能在淹没下恢复。超氧化物和过氧化氢的发展与淹没下的烟酰胺腺嘌呤二核苷酸磷酸氧化酶 (EC 1.6.3.1) 活性呈正相关。简历。Swarna Sub1 在淹没下通过转化酶 (EC 3.2.1.26)、淀粉磷酸化酶 (EC 2.4.1.1) 和蔗糖合酶 (EC 2.4.1.13) 活性更好地响应 ABA(+) 比 Ag-NP(+)。sub1A QTL 对厌氧代谢的功能在 cv. 中得到改善。Swarna Sub1 比 cv。Swarna 支持乙醇脱氢酶 (EC 1.1.1.1) 的多态性表达。最后，
