This work demonstrates enhanced disease resistance in Rosa roxburghii via Harpin Ea, suggesting potential for sustainable crop protection.
Harpin Ea-induced resistance in R. roxburghii is mediated by a synergistic enhancement of physical barriers and systemic activation of phenylpropanoid-flavonoid metabolism. This work provides the first mechanistic evidence linking this dual-layer defense to Harpin Ea-induced disease resistance and establishes a molecular basis for the sustainable application of protein elicitors in fruit crop protection.
