Abstract

Lysigenous aerenchyma is a gas space created by cortical cell death that enables efficient oxygen diffusion within plants and reduces the energy costs associated with root cells. Recent studies have demonstrated the benefits of aerenchyma formation under flooding, drought, and nutrient deficiency, although further studies will be necessary to understand the mechanisms involved.

Keywords: aerenchyma; auxin; ethylene; reactive oxygen species (ROS); root cortical senescence.
