| Abstract | ||
| The study aimed to assess the pathogenicity of the fungus Alternaria alternata on various Tulipa L. species and elucidate its phylogenetic position. The research focused on five specific tulip varieties: T. Albatros, T. Tarda, T. Delta Storm, T. Biflora, and T. Biebersteiniana. Methodologies included molecular analysis, microscopic examinations, cultivation of fungi on PDA, and sequencing of the 18S and 5.8S rRNA genes, as well as the D1/D2 region of the 26S rRNA gene. Results revealed variable pathogenicity across tulip species, with T. Albatros showing complete leaf damage and extensive conidium formation, while T. Biebersteiniana exhibited minimal damage. Factors influencing infection severity included plant variety, conidium formation, and environmental conditions. Sequencing confirmed the fungus's affiliation with the Alternaria genus and highlighted its close relation to other species. The findings underscore the importance of molecular methods for accurate pathogen identification and phylogenetic classification. These results are crucial for developing targeted disease management strategies and enhancing plant resilience in agriculture.The application of the findings is feasible within agriculture to develop resilient varieties and methods for managing the dissemination of A. alternata. Plant diseases involve complex interactions between pathogens and hosts, where fungi like Alternaria alternata disrupt plant physiology through toxin production and enzyme secretion, making effective management crucial | ||
