Embryogenic cells of bananan cv. Rasthali (AAB) have been transformed with the 's' gene of hepatitis B surface antigen (HBsAg) using Agrobacterium mediated transformation. Four different expression cassettes (pHBS, pHER, pEFEHBS and pEFEHER) were utilized to optimize the expression of HBsAg in banana. The transgenic nature of the plants and expression of(More)
Somatic embryos of banana cv. Rasthali (AAB genomic group) were encapsulated in 5% sodium alginate to produce synthetic seeds. The frequency of germination of ecapsulated embryos varied considerably on different gel matrices and substrates used for plant development. Maximum conversion frequency of 66% was noted from encapsulated embryos cultured on MS(More)
Hepatitis B virus ' s ' gene coding for surface antigen was cloned into plant transformation vectors pHER100 and pHBs100 with and without endoplasmic reticulum retention signal, respectively. Transformed tobacco cell lines were analyzed for the integration of the transgene by PCR and Southern blot hybridization. Expression levels as determined by ELISA(More)
Rajeli (AAB), a commercially valuable Indian banana cultivar, is presently under the threat of extinction due to various diseases, warranting development of the strategies for its conservation and incorporation of disease resistance. This elite genotype was successfully regenerated in vitro via establishment of cell suspensions followed by somatic(More)
The drug L-DOPA has been widely used against Parkinson’s disease and is extracted from plants. Due to the increasing demand of this drug, new plant sources need to be discovered in addition to the existing sources. The paper embodies results on Mucuna monosperma, which can be a promising candidate for L-DOPA. The seed powder of this plant contains 5.48% of(More)
Axillary buds of mulberry (Morus indica L) were encapsulated in alginate and agar to produce individual beads. The beads could be stored at 4°C for 45 days without loss of viability. Amongst the encapsulating agents tested, sodium alginate was found to be a better matrix. Encapsulated buds regenerated complete plantlets on an appropriate medium. This(More)
Six different expression cassettes of hepatitis B surface antigen (HBsAg) were used to transform tobacco cell suspension cultures. The transgenic nature of the cells was confirmed by PCR. The secreted HBsAg was assayed by ELISA and analyzed by Western blotting. A maximum of 31 μg antigen/l was obtained in the spent medium from the transformed cells. The use(More)
Tagetes patula L. (Marigold) hairy roots were selected among few hairy root cultures from other plants tested for the decolorization of Reactive Red 198. Hairy roots of Tagetes were able to remove dye concentrations up to 110 mg L(-l) and could be successively used at least for five consecutive decolorization cycles. The hairy roots of Tagetes decolorized(More)
