a novel glucosyltransferase involved in steroid saponin biosynthesis in solanum aculeatissimum.steroidal saponins are widely distributed in many plant species. their diverse structures have resulted in a wide range of applications, including drug and medicine production. it has been suggested that the nature of the non-saccharide and oligosaccharide portions of the saponin molecule both contribute to the properties of individual saponins. despite numerous studies on the occurrence, chemical structure, and varying pharmaceutical activities of steroidal saponins, their biosynthesis pathway ...200515821879
cold-responsive mirnas and their target genes in the wild eggplant species solanum aculeatissimum.low temperature is an important abiotic stress in plant growth and development, especially for thermophilic plants. eggplants are thermophilic vegetables, although the molecular mechanism of their response to cold stress remains to be elucidated. micrornas (mirnas) are a class of endogenous small non-coding rnas that play an essential role during plant development and stress responses. although the role of many plant mirnas in facilitating chilling tolerance has been verified, little is known ab ...201729287583
characterization and engineering of glycosyltransferases responsible for steroid saponin biosynthesis in solanaceous plants.solanaceous plants contain steroid saponins that have diverse biological and pharmacological activities. the structures of their sugar chains play an important role in their activities. a functional glucosyltransferase sagt4a from solanum aculeatissimum glucosylates both steroidal sapogenins and steroidal alkaloids. a potato (s. tuberosum) glycosyltransferase stsgt, which has a high degree of sequence homology with sagt4a, exhibits the same substrate specificity toward steroidal compounds as sag ...200717204296
growth and steroidal saponin production in hairy root cultures of solanum aculeatissimum.hairy root cultures of solanum aculeatissimum were established by trans-formation using agrobacterium rhizogenes strain 15834. root growth and production of steroidal saponin were investigated under various culture conditions. transformed roots grew better in gamborg's b5 medium containing 3 % sucrose under continuous light than in the dark. also, the roots turned light green when cultured under continuous light. green hairy roots produced aculeatiside a (6.71mg ·) l(-1) and aculeatiside b (6.39 ...199524185447

a simple method for purification of glycoalkaloids in the quantitative estimation of solanum khasianum.the property of hydroxylapatite (ca (5) (po (4)) (3) oh) to adsorb plant components selectively is used to isolate and purify steroid glycoalkaloids from solanum khasianum. this method is suitable for botanists seeking higher alkaloid yielding plants and can be performed in experimental plantations where limited laboratory facilities are available.198117402013
plant regeneration from cultured hypocotyl explants of diploid and tetraploid solanum khasianum clarke.plant regeneration through shoot bud formation was induced in cultured hypocotyl explants of diploid and tetraploid varieties of solanum khasianum. optimum regeneration of multiple shoot buds accompanied by rooting occurred on murashige and skoog's medium supplemented with iaa (1 mg/1) and kinetin or benzyladenine (1 mg/1). plantlets obtained in vitro were successfully established in soil.198224257708

the effect of water stress on growth and solasodine content in solanum khasianum.the effect of water stress on growth and development of solanum khasianum (clarke) and on the solasodine content of its fruits, was studied under mild (field experiment) and severe (pot experiment) conditions. under field conditions, vegetative development was inhibited but fruit production or yield were not affected and fruit maturity was enhanced considerably. solasodine content was not affected and yield per plant remained the same with and without irrigation. under conditions of severe water ...198417340252
growth and production of steroid saponin in solanum aculeatissimum during one vegetation period.solanum aculeatissimum (solanaceae) plants, which were cultivated in the open field, were harvested once a month from june 1985 to january 1986. the growth matter and content of steroid saponins, aculeatiside a and b which are precursors of steroid hormones in root, were then measured in order to examine their seasonal variations during one vegetation period. the aerial parts of the plants died of chill and frost in january. in november the dry weight of root reached the maximum, and the content ...198817265223
interspecific somatic hybrids between solanum khasianum and s. aculeatissimum produced by electrofusion.mesophyll derived protoplasts of solanum khasianum clarke and s. aculeatissimum jacq. were fused by electrofusion and resulted in interspecific hybrids. in total, 249 calluses were obtained from which more than 65% produced shoots. from the regenerated plantlets 45% could be identified as hybrids by chromosome counts (4x = 48) and esterase isozyme pattern. most hybrids showing intermediate phenotypic characteristics, had a normal flower morphology with fertile pollen and produced fertile berries ...199424193650
