Study of Direct Adventitious Shoot Regeneration in Pomegranate ( Punicagranatum cv. MalasSaveh ) through Cotyledonary Explants
Punicagranatum cv. Malassaveh is one of the most desirable commercial cultivars in Iran. In thisstudy some experiments were conducted to introduce the best hormonal treatments for directadventitious shoot regeneration from mentioned cultivar via cotyledonary explants. For thispurpose, both liquid and agarMurashige and Skoog (1962) (MS) medium supplemented with BAat 2, 4.5, 9, 13 μM alone and in...
متن کاملImproving adventitious shoot regeneration from cultured leaf explants of Petunia hybrida using thidiazuron
The effect of various concentrations of thidiazuron (TDZ) with or without 2.7 μM of α-naphthalene acetic acid (NAA) on adventitious shoot formation of two Petunia hybrida cultivars was studied. Seeds from ‘Daddy Blue’ and ‘Dreams White’ cultivars were germinated in vitro. Expanded leaves from both seedlings and regenerated shoots were taken as explants. Explants were placed on MS media supplied...
متن کاملFormation 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 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...
