Genetic control of flower shape in Antirrhinum majus.
The asymmetric shape of the Antirrhinum corolla is determined by genes acting differentially along the dorsoventral axis of the flower. Genes so far identified determine asymmetry by acting in dorsal regions. We describe a gene, divaricata, which in contrast to previously identified genes acts in ventral regions of the flower. We show by the analysis of mutant combinations that the divaricata g...
متن کاملGenetic Control of Flower Development by Homeotic Genes in Antirrhinum majus.
Homeotic mutants have been useful for the study of animal development. Such mutants are also known in plants. The isolation and molecular analysis of several homeotic genes in Antirrhinum majus provide insights into the underlying molecular regulatory mechanisms of flower development. A model is presented of how the characteristic sequential pattern of developing organs, comprising the flower, ...
متن کاملOxidation of Flavanones to Flavones with Flower Extracts of Antirrhinum majus (Snapdragon)
Antirrhinum majus, Flavonoid Biosynthesis, Flavanone Oxidase, Apigenin, Luteolin Enzyme preparations from flowers of Antirrhinum majus catalysed the oxidation of naringenin to apigenin and of eriodictyol to luteolin. Enzyme activity was found to be localized in the microsomal fraction. The reaction required NADPH as cofactor and had a pH optimum of about 7.0. The NADPH-dependent microsomal enzy...
متن کاملGenetic Control of Flavanone 3-Hydroxylase Activity and Flavonoid 3'-Hydroxylase Activity in Antirrhinum majus (Snapdragon)
Anthocyanin Biosynthesis, Antirrhinum majus, Flavonoids, Flavanone 3-Hydroxylase, Flavonoid 3'-Hydroxylase, Genetic Control In flower extracts of defined genotypes of Antirrhinum majus, two different hydroxylases were found catalysing the hydroxylation of naringenin and eriodictyol in the 3-position and of naringenin in the 3'-position. The 3-hydroxylase is a soluble enzyme and belongs accordin...
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...
