The exploitation of genetic engineering to enhance plant defenses against nematodes has yielded a variety of successful strategies, primarily focusing on the expression of anti-nematode proteins and RNA interference (RNAi) constructs in host roots. Transgenic resistance to plant-parasitic nematodes can significantly reduce crop damage, with methods, such as RNAi and proteinase inhibitors, showing promise. It seems likely that combining multiple strategies, such as natural resistance genes and nematicidal proteins, could enhance effectiveness, though results vary by crop and nematode type. There is an ongoing debate about environmental and regulatory impacts, despite transgenic approaches being sustainable.
