Abstract—Stevia rebaudiana Bertoni (natural sweetener) belongs to Asteraceae family and can be used as substitute of artificial sweeteners for diabetic patients. Conventionally, it is cultivated by seeds or stem cutting, but seed viability rate is poor. A protocol for callus induction and multiplication was developed to produce large no. of calli in short period. Surface sterilized nodal, leaf ...
Purslane (Portulaca oleracea L.) contains valuable secondary metabolites such as Dopamin, Noradrenaline and Omega-3. This plant is used in various medicinal, food and hygienic industries as well as the treatment of different diseases such as diabetes, heart disease and pain relief. Callus induced from medicinal plants are used to increase the production of secondary metabolities in cell suspens...
Optimization of regeneration methods in cotton is necessary to improve and successful production of transgenic cotton cultivars by tissue culture techniques. Present study was conducted to determine the callus induction and plant regeneration of cotton genotypes through In vitro culture and this carried out using hypocotyl and cotyledon explants from 7-14 day-old. For callus induction the expla...
A simple and efficient plantlet regeneration protocol via direct organogenesis was established for camphor tree (Cinnamomum camphora L.). Stem segments with one node (SN explants) from embryo-cultured seedlings (EC seedlings) were used as explants. Murashige and Skoog (MS) medium supplemented with 0.5 mg/L 2, 4-dichlorophenoxyacetic acid and 2.0 mg/L 6-benzyladenine was used to induce cotyledon...
The purpose of this project was to use and improve current walnut tissue culture methodology to generate plants from somatic embryos and from mature Juglans regia cultivars. Ninty-eight somatic embryo derived plants are now in soil. Fiftyfour of these are derived from the same embryogenic line. Plants from the same line are phenotypically uniform with the exception of 15% which exhibit thickene...
In this study, we report phytoremediation of textile dyes using hairy roots derived through Agrobacterium rhizogenes (NCIM 5140) infection of in vitro leaf and stem explants of a halophyte Sesuvium portulacastrum (L.) L. Leaf explants showed higher frequency of hairy root induction (70%) than stem explants (30%), and maximum number of roots (leaf 42.3 ± 2.4 and stem 50.3 ± 1.7). Transformed nat...
Periwinkle (Catharanthus roseus L.) belongs to the Apocynaceae family and accumulates more than 130 terpenoid indole alkaloids (TIAs), of which two dimeric alkaloids Vinblastine and Vincristine have antineoplastic activity and are useful for treatment of various cancers. Therefore, the production of these drugs has been emphasized in plant tissue culture. In this research, 25 treatments of plan...
Production of genetically and phenotypically stable plantlets is the main purpose in commercial strawberry tissue culture. In this study, different tissues of Fragaria ananassa cv. Camarosa including stipule, apical meristem, leaf and petiole were cultured in Murashige and Skoog (MS) medium supplemented withdifferent concentrations of N6-benzyladenine (BA) (0.5, 1, ...
of embryogenic frequency 88.9 and 72.23 were recorded for stem explants. However, the greatest embryogenic calli fresh weights 14.68 and 9.65 (mg/jar) were derived from leaf explants. Moreover, growth of somatic embryos was investigated during 7weeks. The highest regeneration percentage was achieved for stem explants compared other explants and recorded 88.88 and 66.66 for directly or indirectl...
