Eclipta alba is a medicinal herb, also known as Bhringraj belonging to family Asteraceae. The plant has hepatoprotective, antimicrobial and hair growth promoting properties. The effect of various phytohormones on in-vitro callus induction and shoot regeneration in Eclipta alba from leaf explant was evaluated. The sterilized explants were inoculated on MS medium supplemented with different conce...

An efficient protocol was established for in vitro plant regeneration of Paederia foetada L. (Family. Rubiaceae), a widely used medicinal vine of Bangladesh through callus culture in using nodal segment. Yellowish green nodular callus was observed from nodal segments on MS basal medium supplemented with 1.5 mg/L BAP + 0.5 mg/L NAA within three weeks. Large number of shoots (14.4±1.29) were obta...

Different methods for the isolation of soluble proteins were applied to cell cultures of three apple cultivars (Malus sylvestris Mill.), best results being obtained with a rapid technique based on freezing and thawing. Ultrathin-layer isoelectric focusing followed by an improved silver staining method has shown that proteins from apple callus cultures consist of some 60 to 80 zones, with isoele...

It has been observed in this laboratory (15) that the normally polar distribution of callus growth on tobacco stem explants becomes non-po'ar in the presence of low levels of 2,3,5-triiodobenzoic acid (TIBA), while the amount of callus growth is not diminished. It was thought that this phenomenon might reflect a specific inhibition by TIBA of the polar transport of auxin. Subsequent studies (10...

Callus cultures were induced from leaf segments of Cephaelis ipecacuanha on modified gamborg medium containing 2,4 - dichlorophenoxy acetic acid (2mg/1) Indole acetic acid (1mg/1), kinetin (1mg/1) and sucrose (20g/1). The biogenetic profile for alkaloids was established. The established callus cultures were transferred to modified gamborg medium supplemented with L- DOPA (40 mg/1) and L methion...

One of the tasks in contemporary biotechnology, pharmacology and other fields of human activities is to obtain biologically active substances from plants. They are very essential in the treatment of many diseases due to their actually high therapeutic value without visible side effects. However, sometimes the possibility of obtaining the metabolites is limited due to the reduction of wildgrowin...

The establishment of cell suspension culture from the callus of sugar beet (Beta vulgaris L.) breeding lines and plant regeneration from suspension-derived callus are described in this study. Using different concentrations and combinations of BAP and 2,4-D, the growth patterns of cell suspension cultures were examined during a range of culture periods (0, 3, 5, 7, 9, 11, 13 and 15 days). In all...

An efficient protocol was developed for the induction of callus, somatic embryogenesis and regeneration response of two sugarcane varieties: HSF-243 and HSF-245, in this study. Callus was induced on young leaf explants cultured on Murashige and Skoog’s medium supplemented with different concentration of 2, 4-D singly or in combination with BAP. The highest percentage of callus induction was obs...

Partially expanded male catkins of swamp white oak (Quercus bicolor Willd.) and red oak (Quercus rubra L.) were cultured on Murashige and Skoog (MS) medium supplemented with BA or 2,4-D. Explants on 2,4-D produced a yellow embryogenic callus originating from the junction of the pedicel and peduncle. Subsequent transfers to MS with BA and then MS without growth regulators resulted in callus prol...

In vitro culture of Dioscorea wightii belongs to the family Dioscoreace. An efficient micropropagation protocol was developed for the medicinal plant Dioscorea wightii using nodal segments for axillary shoot proliferation. Callus initiation was stimulated at the basis of the explants in 100% of the cultures by 0.15-1.75μM BA, 0.75-5.0μM Kinetin, 0.15-0.30μM 2iP.The average fresh mass of calluse...
