The Xoral volatile, methyl benzoate, from snapdragon (Antirrhinum majus) triggers phytotoxic eVects in Arabidopsis thaliana
Previously it has been shown that the Xoral scent of snapdragon Xowers consists of a relatively simple mixture of volatile organic compounds (VOCs). These compounds are thought to be involved in the attraction of pollinators; however, little is known about their eVect on other organisms, such as neighboring plants. Here, we report that VOCs from snapdragon Xowers inhibit Arabidopsis root growth...
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 کاملNew Role of Rosea1 in Regulating Anthocyanin Biosynthetic Pathway in Hairy Root of Snapdragon (Antirrhinum majus L.)
We investigated the transcriptional regulation of anthocyanin biosynthesis in hairy roots system by ectopically expressing Rosea1 and Delila and we found something different from previous research. The RT-PCR results revealed that Rosea1 could activate early and late biosynthetic genes tested, including CHS, DFR and ANS. Delila enhanced the expression of CHS weakly, but did not influence DFR or...
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...
