The influence of cytokinins and culture conditions including medium volume, harvest time and elicitation with abiotic elicitors (SA/MeJ) have been studied for the optimal production of biomass and withanolides in the multiple shoot culture of Withania somnifera. Elicitation of shoot inoculum mass (2 g l−l FW) with SA at 100 μM in the presence of 0.6 mg l−l(More)
An efficient, reproducible and genotype-independent in planta transformation has been standardized for sugarcane using seed as explant. Transgenic sugarcane production through Agrobacterium infection followed by in vitro regeneration is a time-consuming process and highly genotype dependent. To obtain more number of transformed sugarcane plants in a(More)
Withanolide is one of the most extensively exploited steroidal lactones, which are biosynthesized in Withania somnifera. Its production from cell suspension culture was analyzed to defeat limitations coupled with its regular supply from the plant organs. In order to optimize the different factors for sustainable production of withanolides and biomass(More)
A generation of nanoparticles research has discussed recently. It is mandatory to elaborate the applications of biogenic nanoparticles in general and anticancereous property in particular. The present study was aimed to investigate the in vitro cytotoxicity effect of biogenic silver nanoparticles (AgNPs) against human breast cancer (MCF-7) cells towards the(More)
For the first time we have developed a reliable and efficient vacuum infiltration-assisted Agrobacterium-mediated genetic transformation (VIAAT) protocol for Indian soybean cultivars and recovered fertile transgenic soybean plants through somatic embryogenesis. Immature cotyledons were used as an explant and three Agrobacterium tumefaciens strains (EHA 101,(More)
Adventitious root cultures derived from leaf derived callus of Withania somnifera (L.) Dunal were treated with methyl jasmonate and salicylic acid independently. Biomass accumulation, culture age, elicitation period, and culture duration were optimized for higher withanolides production in the two best-responding varieties collected from Kolli hills(More)
An efficient and reproducible in planta transformation method was developed for brinjal using seed as an explant. The brinjal seeds were infected with Agrobacterium tumefaciens EHA 105 harbouring pCAMBIA 1301-bar plasmid, and the transformants were selected against BASTA®. Several parameters influencing the in planta seed transformation such as pre-culture(More)
Withania somnifera, an important medicinal plant that possesses a variety of bioactive secondary metabolites collectively known as withanolides. Hairy roots with an initial inoculum mass of 5 g FW were elicited separately with methyl jasmonate (MeJ) and salicylic acid (SA) at various concentrations for different exposure times after 30 days of culture.(More)
Withania somnifera is an important medicinal plant, which is used in traditional medicine to cure many diseases. Flavonoids were determined in the extracts of W. somnifera root (WSREt) and leaf (WSLEt). The amounts of total flavonoids found in WSREt and WSLEt were 530 and 520 mg/100 g dry weight (DW), respectively. Hypoglycaemic and hypolipidaemic effects(More)
This study optimized carbon sources in half MS liquid medium for maximum biomass accumulation and withanolides production in hairy root culture of Withania somnifera. The highest production of withaferin A and withanone was achieved when sucrose and sucrose+glucose were used individually as carbon sources. The hairy root suspension culture supplemented with(More)
