Biosynthesis of the Macrocyclic Diterpene Casbene in Castor Bean (Ricinus communis L.) Seedlings : The Purification and Properties of Farnesyl Transferase from Elicited Seedlings.
FARNESYL TRANSFERASE (FARNESYL PYROPHOSPHATE: isopentenyl pyrophosphate farnesyl transferase; geranylgeranyl pyrophosphate synthetase) was purified at least 400-fold from extracts of castor bean (Ricinus communis L.) seedlings that were elicited by exposure for 10 h to Rhizopus stolonifer spores. The purified enzyme was free of isopentenyl pyrophosphate isomerase and phosphatase activities whic...
متن کاملBiosynthesis of the Macrocyclic Diterpene Casbene in Castor Bean (Ricinus communis L.) Seedlings : Changes in Enzyme Levels Induced by Fungal Infection and Intracellular Localization of the Pathway.
Casbene is a macrocyclic diterpene hydrocarbon that is produced in young castor bean (Ricinus communis L.) seedlings after they are exposed to Rhizopus stolonifer or other fungi. The activities of enzymes that participate in casbene biosynthesis were measured in cell-free extracts of 67-hour castor bean seedlings (a) that had been exposed to R. stolonifer spores 18 hours prior to the preparatio...
متن کاملThe Role of Pectic Fragments of the Plant Cell Wall in Elicitation by a Fungal
Endopolygalacturonase isolated from culture ifitrates of the fungus Rhizopus stolonifer was shown previously to act as an elicitor ofbiosynthetic capacity for the antifungal agent, casbene, in castor bean (Ricinus commais L.) seedlings (S.-C. Lee, C.A. West 1961 Plant Physiology 67:633-639). Selective amidation of exposed carboxyl groups of the pure fungal endopolygalacturonase using intermedia...
متن کاملChemical Investigations of the Castor Bean Plant Ricinus communis
In 2009 a National Security Science and Technology grant was awarded to the Human Protection and Performance Division for the investigation of several forensic aspects of the castor bean plant Ricinus communis. A major focus of this grant was to understand the chemical composition of the seeds, and to ascertain if these differences could be used for provenance classification. This technical rep...
متن کاملDifferential Expression Patterns of Lipid Genes in Developing Seeds of Castor Bean (ricinus Communis L.)
Castor bean (Ricinus communis L.) is one of the most important non-edible oilseed crops. Characterization of seed development and lipid accumulation from female flowers pollinated to mature seeds has been carried out. The temporal expression patterns of 65 lipid genes involved in fatty acid and triacylglycerol biosynthesis using the semi-quantitative RT-PCR technique were also investigated. The...
