15055541 Park CH, Kim S, Park JY, Ahn IP, Jwa NS, Im KH, Lee YH: Molecular characterization of a pathogenesis-related protein 8 gene encoding a class III chitinase in rice. Mol Cells. 2004 Feb 29;17(1):144-50.
A cDNA encoding a class III chitinase (Oschib1) was isolated from a cDNA library constructed from rice leaves infected with the blast fungus Magnaporthe grisea. The cDNA contains an open reading frame of 861 nucleotides encoding 286 amino acid residues with a pI of 5.06. The deduced amino acid sequence of Oschibl has a high level of similarity with class IIIb chitinases of Gladiolus gandavensis (46%) and Tulipa bakeri (49%). A high level of Oschibl mRNA was detected after inoculation with M. grisea or Xanthomonas oryzae pv. oryzae. Expression of Oschib1 was induced more rapidly when an avirulent strain of M. grisea was inoculated (incompatible interaction) than when a virulent strain was used (compatible interaction). Expression of Oschibl was also induced by treatment of signaling molecules such as salicylic acid, ethylene, and methyl jasmonic acid, and by treatment with H2O2 or CuSO4. The induction patterns of Oschibl expression suggest that Oschib1 may be involved in defense response against pathogen infections and may be classified as a member of pathogenesis-related protein 8 in rice.
