Abstract
Metal stress is a major challenge affecting agricultural production, given the increasing global population and the critical need for food. Heavy metal pollution remains a serious threat to production and quality of wheat (Triticum aestivum L.), as a major crop for human nutrition. Understanding the effects of metal stress on plants and their response mechanisms is crucial for optimizing agriculture. Metal stress in plants is commonly induced by heavy metals such as silver, cadmium, lead, and copper. Such heavy metals adversely affect plant growth when present in soil, water, or air. Heavy metal stress can lead to various changes in plant metabolism, including, enzymatic stress, and gene expression alterations. Due to high nutritional requirements and sensitivity to environmental changes, wheat is particularly susceptible to heavy metals-induced stress. Understating the impacts of heavy metals on wheat is crucial for enhancing wheat quality and quantity. Developing resistant varieties and effective agronomic management techniques are crucial to combat wheat production challenges worldwide. This study aimed to explore the impact of silver nitrate (AgNO₃) as an oxidative stress agent and DABCO as an antioxidant on different wheat varieties (Flat and Tajan) and the expression of specific genes, metallothionein and glucanase.
