WebThe two broad categories of host resistance are major gene resistance and quantitative resistance. As discussed earlier, major gene resistance is primarily involved in ETI whereas quantitative resistance involves basal defenses triggered by PTI, recognizing that there are considerable overlaps in the mechanisms triggered by ETI and PTI. WebA “resistant” host has the ability to limit or reduce the pathogenic infection level (or vector infestation) through various defensive mechanisms. A “tolerant” host can minimize the …
