    Amplify the PvNIN promoter region (or promoter region of the gene of interest) from freshly isolated P. vulgaris genomic DNA using the promoter-specific oligo set. Use a high-fidelity polymerase with the following PCR conditions: 95 °C for 5 min; 30 cycles (95 °C for 30 s, 55 °C for 30 s, 72 °C for 1 min); and 72 °C for 5 min. Introduction. PromoterInspector is a program that predicts eukaryotic pol II promoter regions with high specificity in mammalian genomic sequences. The program PromoterInspector focuses on the genomic context of promoters rather than their exact location.. Prediction is based on context specific features which were extracted from training sequences (all mammalian) by a heuristic free approach.

The organ specific promoters developed by this research will provide a method for directing gene expression in the leaf, stem, root, flower, fruit, and seed.

    Expression analysis of four flower-specific promoters of ...

    flower-specific expression, and the region -181 to -161 played a key role in maintaining strong driving power of the promoter. Besides, several enhancer and suppressor regions were also identified ... Orchids comprise one of the largest families of flowering plants and generate commercially important flowers. However, model plants, such as Arabidopsis thaliana do not contain all plant genes, and agronomic and horticulturally important genera and species must be individually studied. Several molecular biology tools were used to isolate flower-specific gene promoters from Oncidium 'Gower ... Promoters are thought to play a major role in adaptive evolution, yet little is known about the regulatory diversity within species, where microevolutionary processes take place. To investigate the potential for evolutionary change in the promoter of a gene, we examined nucleotide and functional variation of the Chalcone Synthase (CHS) cis- regulatory region in Arabidopsis thaliana . CHS is ...

    Recently, we developed a petal-specific promoter using the promoter region of the gene encoding InMYB1 in Japanese morning glory ( Ipomoea nil), which regulates the expression of genes encoding the enzymes for anthocyanin synthesis in petals ( Morita et al. 2006). A flower-specific expressional promoter, PchsA, had been cloned by PCR procedure from total DNA of Petunia hybrida with the primers designed according to the sequence reported by Ingrid M. The cloned region was 514 bp including a TATA-box, a CCAAT-box, a cap site, anther box, a Box2, aBox1, 2G-boxes and 2 copys of TACPyAT box.

    Promoter (genetics) - Wikipedia

    In genetics, a promoter is a region of DNA that leads to initiation of transcription of a particular gene.Promoters are located near the transcription start sites of genes, upstream on the DNA (towards the 5' region of the sense strand).Promoters can be about 100–1000 base pairs long.

    Plasmids 101: The Promoter Region – Let's Go!

    Promoters are about 100 to 1000 base pairs long and found upstream of their target genes. The sequence of the promoter region controls the binding of the RNA polymerase and transcription factors, therefore promoters play a large role in determining where and when your gene of interest will be expressed. The RNA polymerase(s) Based on these findings, we hypothesized that other elements located upstream of the 1.5 kb JcAP1 promoter may be required for flower-specific activation. The JcAP1 promoter characterized in this study can be used to drive transgene expression in both the inflorescence buds and seeds of Jatropha.
