Disease resistance is the ability of an organism to limit the negative effects of pathogens and prevent infection or disease. This ability is crucial for the survival and health of both plants and animals. There are two main types of disease resistance:
- Innate/natural resistance: This is resistance that is naturally present in an organism, not requiring prior exposure to the pathogen. For example, humans have innate immune systems that provide nonspecific resistance to many pathogens.
- Acquired resistance: This type of resistance develops after exposure to a pathogen. Acquired resistance can be active or passive. Active resistance involves the production of antibodies by the immune system to specifically target the invading pathogen. Passive resistance involves external agents that provide protection, such as mothers passing antibodies to babies through breastmilk.
Plants and animals have evolved different mechanisms of disease resistance:
- Plants: Plants have innate physical barriers like waxy cuticles and cell walls that prevent pathogen entry. They also have chemical barriers like antioxidants and phytoanticipins that inhibit pathogen growth. If pathogens breach these barriers, plants activate complex biochemical defense pathways mediated by signal molecules like salicylic acid, jasmonic acid and ethylene. These responses may include production of reactive oxygen species, pathogenesis-related (PR) proteins, or programmed cell death of infected tissues.
- Animals: Animals have innate immune systems involving physical barriers like skin and chemical barriers like antimicrobial peptides and stomach acid. They also have innate cellular responses mediated by phagocytic cells that ingest pathogens and natural killer cells that induce infected cell death. The adaptive immune system provides acquired resistance through the actions of B cells, T cells and antibodies.
Strengthening disease resistance is crucial for protecting both human health and food security.
