Silicon is a beneficial element to improve the biological process, growth, development, and crop productivity. The review mainly focuses on the advantage of crops supplemented with silicon, how Si alleviate abiotic stress as well as regulate the genes and proteins involved in metabolic and biological functions in plants. Abiotic stress causes damage to the proteins, nucleic acids, affect transpiration rate, stomatal conductance, alter the nutrient balance, and cell desiccation which could reduce the growth and development of the plants. To overcome from this problem researchers, focus on beneficial element like silicon to protect the plants against various abiotic stresses. The previous review reports are based on the application of silicon on salinity and drought stress, plant defense mechanism, the elevation of plant metabolism, enhancement of the biochemical and physiological properties, regulation of secondary metabolites and plant hormone. Here, we discuss about the silicon uptake and accumulation in plants, and silicon regulates the reactive oxygen species under abiotic stress, further we mainly focus on the genes and proteins which play a vital role in plants with silicon supplementation. The study can help the researchers to focus further on plants to improve the advancement in them under abiotic stress.
硅是一种有益的元素，可以改善生物过程、生长、发育和作物生产力。本综述主要关注补充硅对作物的益处，硅如何缓解非生物胁迫，以及调节参与植物代谢和生物功能的基因和蛋白质。非生物胁迫会破坏蛋白质、核酸，影响蒸腾速率、气孔导度，改变养分平衡，导致细胞脱水，从而降低植物的生长和发育。为了克服这个问题，研究人员专注于有益元素如硅，以保护植物免受各种非生物胁迫。以前的综述报告基于硅在盐度和干旱胁迫、植物防御机制、植物代谢的提高、生化和生理特性的增强、次生代谢物和植物激素的调节方面的应用。在这里，我们讨论了硅在植物中的吸收和积累，以及硅在非生物胁迫下调节活性氧，我们主要关注的是在硅补充下对植物起关键作用的基因和蛋白质。这项研究可以帮助研究人员进一步关注植物，在非生物胁迫下提高它们的发展水平。
