Hydrolytic Activity and Substrate Specificity of an Endoglucanase from Zea mays Seedling Cell Walls.
An endoglucanase was isolated from cell walls of Zea mays seedlings. Characterization of the hydrolytic activity of this glucanase using model substrates indicated a high specificity for molecules containing intramolecular (1-->3),(1-->4)-beta-d-glucosyl sequences. Substrates with (1-->4)-beta-glucosyl linkages, such as carboxymethylcellulose and xyloglucan were, degraded to a limited extent by...
متن کاملRelease of a Soluble Phytoalexin Elicitor from Mycelial Walls of Phytophthora megasperma var. sojae by Soybean Tissues.
A soluble elicitor of glyceollin accumulation was released from insoluble mycelial walls of Phytophthora megasperma var. sojae after incubation with soybean cotyledon tissue for as little as 2 minutes. Various enzymic and chemical treatments of the released elicitor indicated that the activity resided in a carbohydrate moiety, and gel filtration disclosed the presence of at least two active mol...
متن کاملMolecular Cloning and Ethylene Induction of mRNA Encoding a Phytoalexin Elicitor-Releasing Factor, beta-1,3-Endoglucanase, in Soybean.
Soybean (Glycine max) beta-1,3-endoglucanase (EC 3.2. 1.39) is involved in one of the earliest plant-pathogen interactions that may lead to active disease resistance by releasing elicitor-active carbohydrates from the cell walls of fungal pathogens. Ethylene induced beta-1,3-endoglucanase activity to 2- to 3-fold higher levels in cotyledons of soybean seedlings. A specific polyclonal antiserum ...
متن کاملHost-Pathogen Interactions XXX. Characterization of Elicitors of Phytoalexin Accumulation in Soybean Released from Soybean Cell Walls by Endopolygalacturonic Acid Lyase*
Endopolygalacturonic acid lyase, purified from the phytopathogenic bacterium, Erwinia carotovora , induces phytoalexin accumulation in soybean ( Glycine max L .) cotyledons. This pectin-degrading enzyme releases heat-stable elicitors of phytoalexin accumulation from soybean cell walls, citrus pectin, and citrus sodium polypectate. The most elicitor-active m olecules ob tained by treating soybe...
متن کاملSecretion of active recombinant phytase from soybean cell-suspension cultures.
Phytase, an enzyme that degrades the phosphorus storage compound phytate, has the potential to enhance phosphorus availability in animal diets when engineered into soybean (Glycine max) seeds. The phytase gene from Aspergillus niger was inserted into soybean transformation plasmids under control of constitutive and seed-specific promoters, with and without a plant signal sequence. Suspension cu...
