Using beneficial microorganisms to understand and develop broad-spectrum disease resistance in plants

Key Points

• This review aims to explore how beneficial microorganisms can enhance broad-spectrum disease resistance in plants.
• Reviewed literature on mechanisms by which beneficial microorganisms enhance plant disease resistance through nutritional competition, parasitism, and induction of systemic resistance.
• Investigated molecular mechanisms of effector proteins in promoting symbiotic relationships and activating immune responses in plants.
• Proposed new strategies for developing disease-resistant crop varieties through understanding effector proteins and screening effective strains from healthy plants.
• Beneficial microorganisms enhance plant disease resistance through multiple mechanisms, especially via effector proteins.
• New potential targets for enhancing plant immunity have been identified, providing routes for developing broad-spectrum resistant germplasm.
• Effective strains of beneficial microorganisms were discovered, which can rapidly boost plant disease resistance, highlighting their agricultural significance.
