disease resistance

disease resistance

the ability of some organisms to withstand the attack of PATHOGENS and remain virtually unaffected. The resistance can occur naturally but may be enhanced in a population by ARTIFICIAL SELECTION, as in plant and animal breeding -for example, the breeding of varieties of tomatoes resistant to the fungal disease that produces brown-root rot.
