Identification of Alternaria species using PCR with species-specific primers

Key Points

• The aim is to rapidly identify Alternaria fungi using genetic diagnosis with specific primers targeting the Alt a 1 region.
• Designed species-specific primers for four Alternaria species (A. japonica, A. brassicicola, A. brassicae, A. alternata).
• Focused on the sequence analysis of the Alt a 1 region for identification validation.
• Conducted specificity tests for the created primers.
• The species-specific primers successfully distinguished between the four Alternaria species.
• Genetic diagnosis proved to be a rapid and efficient method for identifying fungal species.
