Disease resistance refers to the ability of a plant to restrict, slow down, or withstand the progression of a pathogen or insect that causes disease. There are many types of disease resistance in plants, both natural and genetically engineered.
Plants have natural defense mechanisms against diseases, including physical and chemical barriers. For example, the waxy cuticle on plant leaves deters fungal growth. Plants also produce antimicrobial compounds like phytoalexins to fight infection. Some plants have R genes which recognize disease-causing microbes and trigger defense responses.
Breeders select plants with strong natural resistance and breed these traits into commercial crop varieties. For example, some tomatoes carry the TMV resistance gene against tobacco mosaic virus. Seed companies develop disease-resistant plant varieties to reduce crop losses for farmers.
Genetic engineering provides new tools for breeding strong disease resistance. Scientists identify R genes in wild plants and insert them into domestic crops. These "resistance genes" trigger protection against major plant diseases. Examples include papayas resistant to papaya ringspot virus and potatoes immune to late blight fungus. Gene editing can also mutate susceptibility genes to boost disease defenses.
No plant has immunity to all pathogens, but building genetic resistance protects important food supplies. As new crop diseases emerge, identifying and integrating effective disease resistance genes through breeding continues to be essential for sustainable agriculture. Society relies on the vigilant efforts of plant breeders to stay ahead of evolving threats.
