Fungal Diseases: A Persistent Threat
Fungal diseases like Fusarium root rot and black rot are major threats, causing substantial yield losses. The review highlights specific genes (e.g., IbCHYR1, IbZnFR) and mechanisms involved in host defense, often hijacked by pathogen effectors.
Viral Infections: Complex Challenges
Viral diseases such as SPFMV and SPCSV cause severe stunting and yield reduction. Synergistic viral infections (SPVD) are particularly damaging. Research focuses on transgenic resistance (CP gene) and gene silencing (miR397 suppression) strategies.
Nematodes & Insects: Key Pest Management
Stem nematodes (Ditylenchus destructor) and sweet potato weevils (Cylas formicarius) lead to significant crop damage. Hormonal responses (JA, SA, ABA) and specialized metabolites (terpenoids, chlorogenic acid) are crucial for defense. Gene IbSPWR1/2 is key for weevil resistance, and IbPIF1 for nematode.
Cross-Stress Interactions: Interconnected Defenses
Sweet potato faces combined biotic and abiotic stresses. Climate change exacerbates pest spread and severity. Genes like IbMPK3, IbMPK6, and IbMIPS1 are implicated in mediating responses to both biotic (e.g., bacterial) and abiotic (e.g., salt, drought) stresses, suggesting complex crosstalk.
Sustainable Strategies: A Holistic Approach
Future strategies include early warning systems, virus-free seedlings, optimizing cultivation (crop rotation, soil microbiota), and genetic improvement via molecular breeding, gene editing, AI, and synthetic biology. Long-term efforts aim for multi-resistant cultivars and global monitoring.
