Role of Lectins in Plant - Microorganism Interactions
The influence of rhizosphere/rhizoplane culture conditions on the ability of various rhizobia to bind soybean seed lectin (SBL) was examined. Eleven strains of the soybean symbiont, Rhizobium japonicun4 and six strains of various heterologous Rhizobium species were cultured in root exudate of soybean ( Glycine max IL.I Merr.) and in association with roots of soybean seedlings which were growing...
متن کاملCell Surfaces in Plant-Microorganism Interactions : VI. Elicitors of Ethylene from Colletotrichum lagenarium Trigger Chitinase Activity in Melon Plants.
Treatment of melon leaves or seedlings with elicitors of Colletotrichum lagenarium, a fungal pathogen of melon, increases chitinase activity. In treated leaves, chitinase is enhanced within the first 6 hours and becomes 2 to 10 times higher than in control leaves after 24 hours. Ethylene is increased simultaneously and is correlated with chitinase elicitation. In the presence of aminoethoxyviny...
متن کاملCell surfaces in plant-microorganism interactions : v. Elicitors of fungal and of plant origin trigger the synthesis of ethylene and of cell wall hydroxyproline-rich glycoprotein in plants.
Treatment of melon hypocotyls or petioles with an elicitor from Colletotrichum lagenarium, a fungal pathogen of melons, causes an initial transitory inhibition of protein synthesis and, after 18 hours, induces the synthesis of a plant cell wall hydroxyproline-rich glycoprotein (HRGP). Microgram amounts of elicitor are sufficient for maximum elicitation of HRGP when the elicitor is injected into...
متن کاملSoil carbon controlled by plant, microorganism and mineralogy interactions
Rhizosphere, a thin area of soil surrounding roots receiving carbon (C) exudation from plants, represents a site of intense competition for available C and nutrient between surface-reactive particles and soil microorganisms. This competition can reduce the amount of available C to a critical level, it becomes limiting for microbial growth and soil organic matter decomposition. On the other hand...
متن کاملReactive oxygen species during plant-microorganism early interactions.
Reactive Oxygen Species (ROS) are continuously produced as a result of aerobic metabolism or in response to biotic and abiotic stresses. ROS are not only toxic by-products of aerobic metabolism, but are also signalling molecules involved in several developmental processes in all organisms. Previous studies have clearly shown that an oxidative burst often takes place at the site of attempted inv...
