Efficient genetic engineering of the medicinal plant, Catharanthus roseus, is essential in improving the production of the pharmaceutically important anticancer compounds, vinblastine and vincristine. Here we optimize several steps in the Agrobacterium-mediated transformation of C. roseus, including antibiotic selection and Agrobacterium elimination(More)
The abundant flavonoid aglycone, naringenin, which is responsible for the bitter taste in grapefruits, has been shown to possess hypolipidemic and anti-inflammatory effects both in vitro and in vivo. Recently, our group demonstrated that naringenin inhibits hepatitis C virus (HCV) production, while others demonstrated its potential in the treatment of(More)
The Catharanthus roseus plant is the source of many valuable terpenoid indole alkaloids (TIAs), including the anticancer compounds vinblastine and vincristine. Transcription factors (TFs) are promising metabolic engineering targets due to their ability to regulate multiple biosynthetic pathway genes. To increase TIA biosynthesis, we elicited the TIA(More)
An Agro-mediated transformation method has been adapted in Catharanthus roseus seedlings for transient overexpression. Our results suggest that Agro-mediated methods may induce defense-related genes, which should be considered in its application. The Fast Agro-mediated Seedling Transformation (FAST) method, which involves the co-cultivation and transient(More)
