چکیده

Two full-length cDNAs (TCH1 and TCH2) were obtained from a cDNA library of Taxus chinensis mainly by the single specific-primer PCR (SSP-PCR) method. Compared with other reported enzymes from Taxus species, the deduced amino acid sequences of TCH1 and TCH2 exhibit significant homologies to hydroxylases that are involved in taxol biosynthesis. These findings imply that the two new genes are closely related to the biosynthesis of taxol/taxoids. Data Accession No: AF545833 and AY374652.

Hazel (Corylus avellana L.) as a New Source of Taxol and Taxanes

Taxol is used to treatment of variety cancers including ovarian, breast, lung, head and neck carcinomas and the AIDS-related Karposi’s carcinoma, and was originally obtained from bark of taxus brevifolia. However the amount of extracted taxol from taxus is extremely low and cannot be considered as a suitable commercial source and it has led to studies for finding new sources of Taxol. In 1998, ...

Identification, Cloning and Structural Analysis of Major Genes from Portulaca oleracea L. Hairy Roots that Involved in the Biosynthesis of Dopamine

Dopamine is one of the important medications of Portulaca oleracea L. To optimize the production of dopamine, one of the methods is the identification and engineering of metabolite pathways. To investigate the tyrosine decarboxylase (TDC) and tyrosinase, which seem to be the most important genes in dopamine synthesis pathway, hairy roots were produced from Portulaca oleracea using Agrobacterium...

Bioinformatics Study and Investigation of the Expression Pattern of Several Important Genes Involved in Glycyrrhizin Synthesis of Glycyrrhiza glabra L. in Autumn and Spring Seasons

Glycyrrhiza is one of the important medicinal plants that is in danger of extinction. Search for finding accessions that have a higher glycyrrhizic acid is very important in breeding programs. Functional genomics methods such as EST sequencing prepare the ability to identify consensus gene families among studied species and interpretation of the genome. In this research, 55960 EST sequences of ...

Taxol biosynthesis: Taxane 13 -hydroxylase is a cytochrome P450-dependent monooxygenase

A central feature in the biosynthesis of Taxol is oxygenation at multiple positions of the taxane core structure, reactions that are considered to be mediated by cytochrome P450-dependent monooxygenases. A PCR-based differential display-cloning approach, using Taxus (yew) cells induced for Taxol production, yielded a family of related cytochrome P450 genes, one of which was assigned as a taxane...
