Disease resistance research focuses on understanding the mechanisms by which organisms, particularly plants and animals, defend themselves against pathogens and diseases. This includes studying the genetic basis of resistance, identifying specific genes or proteins that play a role in immunity, and developing strategies to enhance disease resistance in various species. By understanding these mechanisms, researchers aim to develop more effective and sustainable methods for controlling diseases and reducing the reliance on chemical pesticides or antibiotics. Disease resistance research is crucial for ensuring the health and productivity of crops and livestock, as well as preventing the spread of infectious diseases in humans.
