Subject:
protein synthesis; dose response; chitosan; seedlings; jasmonic acid; linoleate 13S-lipoxygenase; Puccinia graminis; Triticum aestivum; leaves; plant pathogenic fungi; oligosaccharides; chitin; enzyme activity; isozymes; protein composition
Abstract:
... A glycopeptide elicitor prepared from germ tubes of the rust fungus Puccinia graminis Pers. f. sp. tritici Erikss. & Henn (Pgt),as well as chitin oligosaccharides, chitosan, and methyl jasmonate (MJ) stimulated lipoxygenase (LOX) activity (E.C. 1.13.11.12) in wheat (Triticum aestivum) leaves. Immunoblot analysis using anti-LOX antibodies revealed the induction of 92- and 103-kD LOX species after P ...

Subject:
N-acetylglucosamine; Tobacco mosaic virus; Micrococcus luteus; chitosan; cell walls; chitinase; Nicotiana tabacum; chitin; enzyme activity; isozymes; hypersensitive response; leaves; defense mechanisms
Abstract:
... Ten tobacco chitinases (1,4-N-acetyl-veta-D-glucosaminide glycanhydrolase, EC 3.2.1.14) were purified from tobacco leaves hypersensitively reacting to tobacco mosaic virus. The 10 enzymes, which belong to five distinct structural classes of plant chitinases, were incubated with several potential substrates such as chitin, a beta-1,4 N-acetyl-D-glucosamine (GlcNAc) polymer, chitosan (partially deac ...

Subject:
Bacillus cereus; chitin; chitinase; chitosan; chitosanase; culture media; enzyme activity; isozymes; plant pathogens; polyacrylamide gel electrophoresis
Abstract:
... Bacillus cereus MP-310 was incubated on various culture media substrates as LB, colloidal chitin, chitosan powder, and chitosan beads to investigate the concurrent expression patterns of chitinase and chitosanase isozymes by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Chitinase activity increased rapidly with a maximum level after 6 days of incubation in CM-chitin medium. ...
