Abstract
A transformation method based on a dominant selectable marker (benomyl resistance) was developed for the rice blast fungus Magnaporthe grisea. The heterologous gene for β-tubulin from Neurospora crassa (pBT3) was used to obtain benomyl-resistant M. grisea transformants at a frequency of 20 to 30/μg of DNA. Control transformations carried out with a plasmid conferring hygromycin resistance or a derivative of pBT3 containing a repetitive DNA sequence, yielded the same frequency of transformation as that of pBT3. Molecular analysis of the transformants indicated multiple integration of the vector DNA.
