Formation of monoterpenes in Antirrhinum majus and Clarkia breweri flowers involves heterodimeric geranyl diphosphate synthases.
The precursor of all monoterpenes is the C10 acyclic intermediate geranyl diphosphate (GPP), which is formed from the C5 compounds isopentenyl diphosphate and dimethylallyl diphosphate by GPP synthase (GPPS). We have discovered that Antirrhinum majus (snapdragon) and Clarkia breweri, two species whose floral scent is rich in monoterpenes, both possess a heterodimeric GPPS like that previously r...
متن کاملReconsideration of the use of deionized water as vase water in postharvest experiments on cut flowers
The relevance of deionized water as a control treatment in vase life experiments and the effects of major tap water components on cut flower water balance were investigated. Chrysanthemum (Dendranthema x grandiflorum Tzvelev cv. Cassa) was used in all experiments. Deionized water gave a sharp decrease in fresh weight of the cut flowers after 1–3 days. This decrease was absent in tap water. Afte...
متن کاملTemperature shift coordinately changes the activity and the methylation state of transposon Tam3 in Antirrhinum majus.
The transposition frequency of Tam3 in Antirrhinum majus, unlike that of most other cut-and-paste-type transposons, is tightly controlled by temperature: Tam3 transposes rarely at 25 degrees C, but much more frequently at 15 degrees C. Here, we studied the mechanism of the low-temperature-dependent transposition (LTDT) of Tam3. Our results strongly suggest that LTDT is not likely to be due to e...
متن کاملMolecular cytogenetic characterization of the Antirrhinum majus genome.
As a model system in classical plant genetics, the genus Antirrhinum has been well studied, especially in gametophytic self-incompatibility, flower development biology, and transposon-induced mutation. In contrast to the advances in genetic and molecular studies, little is known about Antirrhinum cytogenetics. In this study, we isolated two tandem repetitive sequences, CentA1 and CentA2, from t...
متن کاملChemotropic Response of the Pollen of Antirrhinum majus to Calcium.
An improved spectrophotometric method for the determination of lipoxidase activity was developed and applied in studies of the purified enzyme and crude enzyme preparations from leguminous seeds, with linoleic acid solubilized in Tween 20 as the substrate. The optimum pH was found to be 7.0, 6.5, 6.0, and 5.5, for purified soybean lipoxidase and for the crude lipoxidases extracted from gram flo...
