Journal ArticleDOI
Elicitation: A biotechnological tool for enhanced production of secondary metabolites in hairy root cultures
TL;DR: This is a comprehensive review about the progress in the elicitation approach to hairy root cultures from 2010 to 2019 and the information provided is valuable and will be of interest for scientists working in this area of plant biotechnology.
Journal ArticleDOI
Changes in morphological phenotypes and withanolide composition of Ri-transformed roots of Withania somnifera.
TL;DR: The first report of the presence of withasteroids in undifferentiated callus cultures of W. somnifera is reported, and this is the first detection of withaferin A in the roots of the plant.
Journal ArticleDOI
Genetic transformation of Tylophora indica with Agrobacterium rhizogenes A4: growth and tylophorine productivity in different transformed root clones
TL;DR: An efficient transformation system for Tylophora indica is developed, using Agrobacterium rhizogenes strains LBA9402 and A4 to infect excised leaf and stem explants and intact shoots at different sites to induce transformed roots.
Journal ArticleDOI
Production of withaferin A in shoot cultures of Withania somnifera.
Swagata Ray,Sumita Jha +1 more
TL;DR: Multiple shoot cultures of Withania somnifera were established from single shoot tip explants and their potential for the production of two principle withanolides, withaferin A and withanolide D was investigated.
Journal ArticleDOI
Genetic transformation of Bacopa monnieri by wild type strains of Agrobacterium rhizogenes stimulates production of bacopa saponins in transformed calli and plants
TL;DR: There is an overall stimulatory effect on accumulation of bacopa saponins in transformed plants and cells of B. monnieri establishing the role of endogenous elicitation by Ri T-DNA of A. rhizogenes.
