Abstract: To investigate bending spore corn leaf spot fungus pathogenic mechanism and genetic variation characteristics, this study using restriction enzymes mediated gene integration technology(REMI)of Curvularia lunata genetic transformation, received 109 stable mutant strains. PCR detection results showed that the plasmid pUC-JS has successfully imported mutant strains, into the son has both single copy and copy, albino strain single copy insert frequency was 40%. In addition, an albino corn bending spore bacteria leaf spot REMI contrast with wild strain of the mutant strains colony color, and also significantly weaker than wild on pathogenic strains. Plasmid save, sequencing and analysis of blast speculated that inserts may result in the loss FAD3 gene function.

Key words: Curvularia lunata REMI, Albino mutant, Pathogenic
