| Rice is the most important food for a significant portion of the world's population, especially in Asia. The infection of rice plants with Fusarium species is a major global problem. For the morphological and phylogenetic identification of Fusarium species associated with rice, a widespread sampling was conducted from the root, crown, leaf sheath, and stem of the rice plants in various rice-cultivating areas across Fars, Golestan, Guilan, Isfahan, Khuzestan and Mazandaran provinces. Species-specific primers were used to identify three closely related species: F. fujikuroi, F. proliferatum, and F. verticillioides, which could not be distinguished based on morphological criteria alone. By combining morphological characteristics and sequence data of TEF1-α and β-tubulin genomic regions, nine species including F. fujikuroi, F. verticillioides, F. proliferatum, F. globosum, F. andiyazi, F. anthophilum, F. incarnatum, F. culmorum and F. oxysporum were identified among 242 isolates examined. This study reports the first occurrence of Fusarium andiyazi on rice in Iran. In addition to the known causal agents of bakanae disease, the pathogenicity test revealed that two additional species F. culmorum and F. anthophilum can also be considered agents of bakanae disease on rice. | ||
