Maize is the most important cereal crop globally. However, in recent years, maize production faced numerous challenges from environmental factors due to changing climate. Salt stress among major that negatively impact productivity worldwide. To cope with salt stress, plants developed various strategies, such as producing osmolytes, increasing antioxidant enzyme activity, maintaining reactive oxygen species homeostasis, and regulating ion transport. This review provides an overview of intricate relationships between several plant defense mechanisms, including enzymes, species, hormones, ions (Na+, K+, Cl−), which are critical for tolerance maize. It addresses regulatory strategies key involved tolerance, aiming foster a comprehensive understanding networks These new insights will also pave way further investigations into significance these regulations elucidating how coordinates its system resist stress.
