Mendelian Inheritance of Chromosome Shape in Matthiola.
A variety of stock (Matthiola ilzcana R. Br.) known as Snowflake has been shown by FROST (1919) to produce frequent mutants of at least eight distinct kinds. These mutant forms are genetically inconstant, part of the progeny always being normals. These forms have been determined (FROST and MANN 1924, and papers in preparation) to be trisomic. Within, the variety Snowflake, all plants cytologic...
متن کاملGenetic Control of Chalcone Synthase Activity in Flowers of Matthiola incana R. Br
Anthocyanins, Flavonoids, Chalcone Synthase, Genetic Control, Matthiola incana Chalcone synthase activity was demonstrated in enzyme preparations from flowers of defined genotypes of Matthiola incana (stock). The product formed from 4-coumaroyl-CoA and malonylCoA was naringenin and not the isomeric chalcone, because chalcone isomerase was also present in the reaction mixture. Chalcone synthase ...
متن کاملMicropropagation of Matthiola incana using BA and IBA. Behzad Kaviani
Matthiola incana (Brassicaceae) is an important ornamental plant, which is used as cut flower, pot plant, and landscape. Traditionally, it is propagated via seeds, but interest is given in vegetative propagation of parental lines as well as superior single plants. Micropropagation by organogenesis is an efficient in vitro propagation method for Matthiola incana. Starting from seeds, apical bud ...
متن کاملAnthocyanin Biosynthesis in Flowers of Matthiola incana Flavanone 3- and Flavonoid 3'-Hydroxylases
Anthocyanins, Flavonoids, Biosynthesis, Flavanon 3-Hydroxylase, Flavonoid 3'-Hydroxylase, Matthiola incana Enzyme preparations from flowers of defined genotypes o f Matthiola incana contain two dif ferent hydroxylases for hydroxylation of naringenin in the 3and 3'-position, respectively. The 3-hydroxylase is a soluble enzyme and requires as cofactors 2-oxoglutarate, Fe2+ and ascorbate. Besides...
متن کاملConversion of Dihydroflavonols to Flavonols with Enzyme Extracts from Flower Buds of Matthiola incana R. Br
Dioxygenase, Flavonoid Biosynthesis, Flavonols, Matthiola incana Soluble enzyme preparations from flower buds of Matthiola incana catalysed the conversion of dihydrokaempferol to kaempferol and of dihydroquercetin to quercetin. The reaction required 2-oxoglutarate, ascorbate and Fe2+ as cofactors and had a pH-optimum at about 7.0. Highest enzyme activity was already present in the youngest buds...
