In present report effects of explants type, basal media and plant growth regulators (PGRs) were tested for induction of indirect somatic embryogenesis in medicinally important plant Silybum marianum L. Leaf, petiole and root explants were exploited in vitro on B5 (Gamborg), SH (Schenk and Hildebrandt) and MS (Murashige and Skoog) media for induction of embryogenic callus followed by somatic emb...

The present study was conducted to investigate the effects of different concentrations and combinations of plant growth regulators (PGRs) on callus induction of Tecomella undulata (Sm) Seem. The leaf segments were used as explants and cultured on Murashige and Skoog (MS) medium supplemented with different concentrations of auxins such as NAA, 2,4-D, IAA and cytokikinins like BAP and KIN alone a...

Cinnamomum tamala is a multipurpose economically important plant. The leaves and bark are used as spice and contributes to the different ‘Ayurvedic’ drug preparation. Due to over-exploitation for spice and medicines, the species is vulnerable in its natural habitat. In the present study, a successful attempt was made for callus mediated plant regeneration of the species from leaf and zygotic em...

Leaf explants of kaladium dwubarwne Caladium bicolor (Aiton) Vent., were cultured in vitro on MS media supplemented with 25 different concentrations of BAP and NAA in order to determine the appropriate concentrations for micropropagation. All combinations induced callus formation on explants. Callus production on leaves explants grown on control medium was very low. The medium enriched with 4 m...

background and objectives: grape has high nutritional value and it is an economically important horticultural plant in the world. iran has seventh producer grape rank in the world. today tissue culture is one of technique which can be used in grape propagation and breeding. material and method: in order to optimization of callus induction and micropropagation of grape in vitro condition, this i...

The seeds of ten different genotypes of chickpea (Cicer arietinum L.) originated from Egypt, ICARDA and Saudi Arabia, were used to screen their tissue culture response on various media combination. MS media supplemented with 1, 2 and 4 mg of each of IBA and transzeatin /l, were tested. The results showed that stem results were far better from leaves explants. The callus induction ranged from 6....

In this study, studies were conducted to optimize callus and suspension culture methods for in vitro mutation breeding purple orange carrots. Following this, the developed mutant lines subjected salt stress selection. The study determined optimal agar dose. first germination, 50% root-cotyledon formation genuine leaf carrot seedlings analyzed daily which was continued with 7g/L cotyledon hypoco...

Foliar explants of Nicotiana tabacum cv Xanthi n.c. were cultured on four different media: a basal medium, basal medium plus benzyladenine, basal medium plus 2,4-dichlorophenoxyacetic acid (2,4-D), and the basal medium containing both hormones. No differentiation or cell division occurred in leaf explants cultured on the basal medium. Addition of benzyladenine caused the formation of buds on th...

Andrographis lineata is an herbal medicinal plant used in traditional medicine as a substitute for Andrographis paniculata. Here, using mature leaf explants of A. lineata we demonstrate for the first time the callus induction established on MS medium containing 1.0 mg l-1 IAA. Dried callus was subjected to solvent extraction with acetone. Further the acetone residue was separated by silica gel ...

Using a two-component transgene system involving two epiallelic variants of the invertedly repeated transgenes in locus 1 (Lo1) and a homologous single-copy transgene locus 2 (Lo2), we have studied the stability of the methylation patterns and trans-silencing interactions in cell culture and regenerated tobacco (Nicotiana tabacum) plants. The posttranscriptionally silenced (PTGS) epiallele of t...
