PhMYB4 fine-tunes the floral volatile signature of Petunia×hybrida through PhC4H
In Petunia × hybrida cv 'Mitchell Diploid' (MD), floral volatile benzenoid/phenylpropanoid (FVBP) biosynthesis is controlled spatially, developmentally, and daily at molecular, metabolic, and biochemical levels. Multiple genes have been shown to encode proteins that either directly catalyse a biochemical reaction yielding FVBP compounds or are involved in metabolite flux prior to the formation ...
متن کاملBrassinosteroid biosynthesis and signalling in Petunia hybrida
Brassinosteroids (BRs) are steroidal plant hormones that play an important role in the growth and development of plants. The biosynthesis of sterols and BRs as well as the signalling cascade they induce in plants have been elucidated largely through metabolic studies and the analysis of mutants in Arabidopsis and rice. Only fragmentary details about BR signalling in other plant species are know...
متن کاملThe S-Ribonuclease Gene of Petunia hybrida
To determine the ability of isolated S-locus promoter sequences to direct organ-specific gene expression, we used microprojectile bombardment to introduce chimeric S-allele/&glucuronidase genes into different tissues of Petunia hybrida for transient expression. Histochemical staining showed that S-locus/B-glucuronidase fusions were expressed in pistil, ovary, and petal tissue. No expression of ...
متن کاملStylar peroxidase and incompatibility reactions in Petunia hybrida.
Self-, cross- and non-pollinated styles of Petunia hybrida were treated with 3-3'-diaminobenzidine for the ultrastructural localization of peroxidase activity. Wall peroxidases were absent in cross-pollinated styles, but they were detectable as an osmiophilic deposit on the cell walls of the outer portion of the transmitting tissue in self- and non-pollinated styles. The cell layer showing pero...
متن کاملEncoding of a cytochrome P450-dependent lauric acid monooxygenase by CYP703A1 specifically expressed in the floral buds of petunia hybrida.
The cDNA clone of novel cytochrome P450 CYP703A1 from petunia floral buds was isolated by RT-PCR. The nucleotide sequences of this cDNA clone contained the open reading frame that has been predicted to encode polypeptides consisting of 539 amino acid residues. A significantly high level of the transcript of the cyp703A1 gene was found in the early stage of petunia flower buds, but not in the le...
