Nanoparticles (NPs) play a key role in drought tolerance in plants. NPs can be prepared by two main methods (physical or chemical). Green synthesis of NPs is an environmentally friendly technique. There are different groups of NPs, such as metal-based, metal-oxide-based, and carbon-based NPs. NPs increase the expression of genes under drought stress (DS) and protect plants from toxic effects.
