Functional analysis of <i>MeFER4</i> in regulating ROS homeostasis during abiotic stress responses in <i>Arabidopsis</i>
The <italic>MeFER4</italic> gene in cassava (<italic>Manihot esculenta</italic> Crantz) encodes a ferritin-like protein involved in stress responses, particularly under drought and oxidative stress. This study explores the role of MeFER4 in regulating oxidative stress in transgenic <italic>Arabidopsis</italic>. Overexpression of <italic>MeFER4</italic> enhanced sensitivity to various stresses, including drought, oxidative, salt, and osmotic stress, with increased levels of reactive oxygen species (ROS) and altered expression of ROS-related genes in <italic>Arabidopsis</italic>. Furthermore, interactions between MeFER4 and antioxidant enzymes (APX1 and APX3), suggest its role in managing ROS homeostasis. These findings highlight MeFER4 as a key regulator of oxidative stress responses, offering the potential for improving stress tolerance in crops.
