稻属,含水稻,对维持全球粮食安全至关重要。该属有许多复杂的分子机制来应对环境压力,特别是在开花等脆弱阶段。最近的研究发现,关键的参与和遗传修饰可以增加对压力的抵抗力,包括褪黑素的外源性应用,尿囊素,和海藻糖以及遗传领域的OsSAPK3和OsAAI1。由于气候变化和人为原因,海平面上升引起了人们对盐度压力的关注。它通过渗透调节和离子稳态来解决,由P5CS等基因介导,P5CR,GSH1、GSH2和SPS,和像NHX这样的离子运输机,NKT,SKC,分别。抗氧化剂的复杂作用减少了氧化损伤,正在清理RONS。基因的复杂作用介导冷胁迫,研究强调了OsWRKY71,microRNA2871b,OsDOF1和OsICE1。有必要研究OsRbohA等蛋白质在ROS控制中的作用机制以及调节基因在应激反应中的作用。这是高度相关的,因为气候变化将引发许多环境变化,如果不采取某些对策,将对生产和全球粮食安全产生不利影响。总的来说,本研究旨在揭示逆境条件下水稻植物ROS和RNS信号网络的分子复杂性,最终目标是为这个重要的农业属提供增强胁迫耐受性和作物性能的策略。
The Oryza genus, containing Oryza sativa L., is quintessential to sustain global food security. This genus has a lot of sophisticated molecular mechanisms to cope with environmental stress, particularly during vulnerable stages like flowering. Recent studies have found key involvements and genetic modifications that increase resilience to stress, including exogenous application of melatonin, allantoin, and trehalose as well as OsSAPK3 and OsAAI1 in the genetic realm. Due to climate change and anthropogenic reasons, there is a rise in sea level which raises a concern of salinity stress. It is tackled through osmotic adjustment and ion homeostasis, mediated by genes like P5CS, P5CR, GSH1, GSH2, and SPS, and ion transporters like NHX, NKT, and SKC, respectively. Oxidative damage is reduced by a complex action of antioxidants, scavenging RONS. A complex action of genes mediates cold stress with studies highlighting the roles of OsWRKY71, microRNA2871b, OsDOF1, and OsICE1. There is a need to research the mechanism of action of proteins like OsRbohA in ROS control and the action of regulatory genes in stress response. This is highly relevant due to the changing climate which will raise a lot of environmental changes that will adversely affect production and global food security if certain countermeasures are not taken. Overall, this study aims to unravel the molecular intricacies of ROS and RNS signaling networks in Oryza plants under stress conditions, with the ultimate goal of informing strategies for enhancing stress tolerance and crop performance in this important agricultural genus.
