calystegines were isolated from the root cultures of physalis divaricata, p. pubescens, p. philadelphia,and p. philadelphia (solanaceae). calystegines of p. divaricata were identified as calystegine a3, a5, b1 and b2, with concentrations of 6.99, 4.41, 8.52, and 14.7 ?g/g in fresh mass, respectively. root cultures of p.pubescens contain calystegine a3, b1 and b2, p. philadelphia only contains c...

Coeloneurum, Espadaea, Henoonia, and Goetzea are shrubs and trees that are endemic to the islands of Cuba, Hispaniola, and Puerto Rico in the Greater Antilles. A phylogenetic analysis was conducted to elucidate the evolutionary relationships among them and with other major lineages of the Solanaceae. DNA sequences of the chloroplast genes ndhF, rbcL, and trnL-trnF intron and intergenic spacer w...

The Solanaceae, Rosaceae, and Scrophulariaceae families all possess an RNase-mediated self-incompatibility mechanism through which their pistils can recognize and reject self-pollen to prevent inbreeding. The highly polymorphic S-locus controls the self-incompatibility interaction, and the S-locus of the Solanaceae has been shown to be a multi-gene complex in excess of 1.3 Mb. To date, the func...

The presence of different glutamine synthetase isoenzymes in different Solanaceae plants and their relative antigenicities against antiglutamine synthetase from tomato leaf serum were studied. All the plants tested showed one glutamine synthetase isoenzyme except for Mandragora autumnalis, which showed two, after discontinuous polyacrylamide gel electrophoresis and specific in situ assay. Antig...

Microcomplement fixation was employed to compare the immunological differences that occur between purified inhibitor I from potato tubers, the four purified protomers that comprise it, and inhibitor I from tuber and leaf extracts. Total inhibitors of chymotrypsin and trypsin in leaves of seven genera of the Solanaceae were identified by enzymatic assay. In leaves of three genera, Solanum, Lycop...

A survey was carried out in District Hamirpur for documentation and information from natives about the ethnomedicines uses of plants. The indigenous knowledge of local uses of plants by natives,was collected through personal interviews during field of this hilly district of Himachal Pradesh.The communities in the different villages of this district are gathering the long-hidden indigenous knowl...

in vitro multiple shoot regeneration of solanum nigrum l., an indian medicinal plant was accomplished on ms medium utilizing shoot tip and nodal explants. direct multiple shoots differentiated within 6 weeks when explants were cultured on ms medium containing bap (1.0-5.0 mg/l) and kin (1.0-5.0 mg/l) individually. among various concentrations of cytokinins tested, maximum number of multiple sho...

plants are the important sources of drugs. secondary metabolites are responsible for therapeutic propertiesin plants. three compounds including (-)-hyoscyamine, its racemate atropine, and scopolamine (hyoscine) are the most famous tropane alkaloids in the solanaceae familly. nowadays, attempts to developthese alkaloids in biotechnological procedures which are principally based on the hairy root...
