PCR-RFLP profiles generated by digestion of Fusarium histone H3 gene amplification products with DdeI and CfoI. Electrophoresis were performed on 3% agarose gels at 3 V/cm. Lanes M, 100-bp ladder (1,500, 1,000, 900, 800, 700, 600, 500, 400, 300, 200, and 100 bp); lane A, mating population A; lane B, mating population B (F. subglutinans associated with sugarcane); lane C, mating population C; lane D, mating population D; lane E, mating population E (F. subglutinans associated with maize); lane F, mating population F; lane G, mating population G; lane H, F. subglutinans f. sp. pini (mating population H); lane 1, F. subglutinans from maize; lane 2, F. subglutinans from pineapple (F. subglutinans f. sp. ananas); lane 3, F. subglutinans from mango.
