The process of surface sterilizing plant materials is a difficult step in constructing tissue culture technique. Nodal explants from potted plants Solanum tuberosum L. grown the screenhouse were given various sterilization procedures before being introduced into sterile Murashige and Skoog (MS) culture. A total 16 treatments performed with varied periods immersion two sterilant successions: 70%...

in vitro propagation of az x m9 new apple rootstock resulted of breeding program of vegetative apple rootstock in iran was investigated. nodal explants were inoculated in murashige and skoog (ms) medium supplemented with various concentrations of 6-benzylaminon purine (bap) (0.4, 0.8 and 1.2 mg/l) alone or with naphthalene acetic acid (naa) (0.1 mg/l). we examined the effect of different concen...

Article info: Received: 9 April 2014 Accepted: 6 August 2014 ABSTRACT An effective in vitro culture system for mature nodal segments of European plum (Prunus domestica) was established. Several important aspects of regeneration from nodal explants were studied for adaptation of European plum in Bangladesh. Leaf explants were used for callus induction and 1⁄2 MS media supplemented with 1.0 mg/l ...

Sinus nodal cells can generate a diastolic or "pacemaker" depolarization at the end of an action potential driving the membrane potential slowly up to the threshold for firing the next action potential. It has been proved that adult cardiac stem cells (CSCs) can differentiate into sinus nodal cells by demethylating agent. However, there is no report about adult CSCs-derived sinus nodal cells wi...

The carnation (Dianthus caryophyllus) is one of the top-selling commercial cut-flower crops worldwide, which is very susceptible to infections. Micro propagation is an advanced biotechnological system for producing free of pathogen colonies. Too many factors may limit micro propagation of plants, which the most important of them is contamination (e.g., fungal, bacterial and viral infections). T...

The author has been using post-nodal segments of early chick blastoderms as an experimental system to study early morphogenesis and differentiation. The segment is produced by a transverse cut at about 0-4 mm from the primitive pit and is known for its very limited potencies in chorio-allantoic transplantation or in culture, in contrast to anterior parts containing Hensen's node (Hunt, 1931; Wi...
