Fusarium mangiferae associated with mango malformation in the tarai region of the Uttarakhand state of India.

Mango malformation is the most dangerous disease to mango worldwide. There are hints that Fusarium mangiferae might be one of the probable casual agents of disease. Recently, we reported on Fusarium isolates obtained from the mango tarai region of Uttarakhand acquiring morphological features of F. mangiferae. Here, further confirmation of Fusarium isolates were made by PCR amplification using primers specific to the translation elongation factors 1α and β-tubulin gene of F. mangiferae. Further, SDS-PAGE and RAPD profiles showed genetic variability among isolates of F. mangiferae. This study provides further direct evidence of involvement of different strains of F. mangiferae in malformation diseases of mango in the tarai region of the Uttarakhand state.
