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
The root: a potential new source of competent cells for high-frequency regeneration in Tylophora indica.
TL;DR: A new micropropagation system for Tylophora indica, an important medicinal plant in India, using root explants as starting material was developed, with MS medium supplemented with 10.72 μM BA being the most effective in inducing FEC and somatic embryogenesis.
Journal ArticleDOI
Spontaneous plant regeneration in transformed roots and calli from Tylophora indica: changes in morphological phenotype and tylophorine accumulation associated with transformation by Agrobacterium rhizogenes
TL;DR: Transformed roots induced by the bacterium grew in axenic culture and produced shoots or embryogenic calli in the absence of hormone treatments, however, hormonal treatment was required to regenerate shoots in root explants of wild type control plants.
Journal ArticleDOI
Transgenic mimicry of pathogen attack stimulates growth and secondary metabolite accumulation
Kuntal Narayan Chaudhuri,Kuntal Narayan Chaudhuri,Sudripta Das,Moumita Bandyopadhyay,Andreja Zalar,Albert Kollmann,Sumita Jha,David Tepfer +7 more
TL;DR: It is shown that transgenic mimicry is correlated with increased secondary metabolite production in transformed root cultures and whole plants, and proposed that natural transformation with genes encoding the production of microbial elicitors could influence interactions between plants and other organisms.
Journal ArticleDOI
Biotechnological approaches for the production of forskolin, withanolides, colchicine and tylophorine
TL;DR: The world market formedicinal and aromatic plants (MAPs) is huge; India is a major exporter of raw MAPsand processed plant-based drugs (Lambert et al., 1997);75% of the total exports from India are sent to sixcountries, namely France, Germany, Japan, Switzerland, the UK and the USA.
