Viral Challenges in Wheat: Comprehensive Diagnosis and Innovative Management Approaches.

Area of Science:

• Plant Pathology
• Virology
• Agricultural Science

Background:

• Wheat (Triticum aestivum L.) is a vital global staple crop facing substantial yield losses (up to 80%) due to over 50 viral diseases.
• Key viral threats include wheat streak mosaic virus (WSMV), barley yellow dwarf viruses (BYDVs), and others, transmitted by vectors like wheat curl mites and aphids.
• Accurate diagnosis is difficult due to overlapping symptoms and the microscopic nature of viruses.

Purpose of the Study:

• To provide a comprehensive review of wheat viral diseases.
• To analyze cutting-edge diagnostic tools and sustainable management strategies.
• To identify knowledge gaps and future research directions for virus-resistant wheat.

Main Methods:

• Review of current literature on wheat viral diseases, diagnostics, and management.
• Analysis of molecular and serological diagnostic techniques (ELISA, RT-PCR, CRISPR, biosensors).
• Evaluation of integrated management strategies including resistant breeding, vector control, and RNA interference (RNAi).

Main Results:

• Advanced diagnostic tools like RT-PCR and CRISPR-based detection offer improved virus identification.
• Integrated management strategies are crucial as chemical treatments are ineffective.
• Breeding for resistance, vector control, and RNAi show promise for disease mitigation.

Conclusions:

• Effective management of wheat viral diseases requires integrated strategies and advanced diagnostics.
• Further research is needed to develop robust virus-resistant wheat varieties.
• Addressing these challenges is critical for ensuring global food security.
