Identification of a Putative Vacuolar Serine Protease Gene in the Rice Blast Fungus, Magnaporthe grisea

Abstract

We identified and cloned a gene designated SPM1, encoding a serine protease from the rice blast fungus Magnaporthe grisea. SPM1 is a single-copy gene, encoding a subtilisin-like serine protease with 536 amino acids. Analyses of the deduced amino acid sequence of SPM1 suggested that SPM1 would be localized in a vacuole, an important organelle in pathogenicity. © 2002 by Japan Society for Bioscience, Biotechnology, and Agrochemistry.
