    Mango (Mangifera indica) is a commercially significant fruit crop worldwide. Leaf spot diseases are common in mango orchards, severely impacting yields. Mycoviruses hold promise as potential biocontrol agents. To explore this potential, fungi were isolated from mango leaf spot lesions, and six strains harboring double-stranded RNA (dsRNA) were identified. Using BLASTx analysis of the NCBI nr database, twenty-seven mycovirus-related contigs were detected, corresponding to 10 distinct viruses grouped into eight lineages: Alternaviridae, Chrysoviridae, Partitiviridae, Polymycoviridae, Orthototiviridae, Deltaflexiviridae, Narnaviridae, and Bunyaviricetes. Full genomic sequences of these viruses were characterized and verified to be associated with their host fungi. The findings include six novel mycoviruses, three discovered in new hosts, and one virus strain, underscoring the diversity and taxonomy of mycoviruses in mango leaf spot-associated fungi.
