abstract gerbera is one of the most demanded plants in commercial cut flowers plants. optimizing the micro-propagation of new cultivars is therefore important. in this research “red explosion” cultivar was used and capitola (as explants) were directed to a modified solid murashigue and skoog medium with four concentration of tdz (0.25, 0.50, 0.75 and 1.00 mgl-1) for regeneration. three concentr...

Wild plant species are of great interest as a source pharmacologically valuable compounds but number them endemic and/or endangered ones. Modern biotechnology can provide reliable methods for their utilization without disturbing natural populations. In vitro culture Rhodiola being intensively developed to include into various biotechnological programmes. Aim. Development protocol direct rosea L...

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...

Cereus peruvianus callus have a lot of alkaloids compounds and medicine extracted, which is important in medicine, medical and agricultural industries. The experiments were performed using Complete Randomized Design (CRD) and results were analyzed using one way ANOVA. MS medium supplemented with different concentrations of (2,4-D), kinetin and NAA were used. The study was carried out on Increas...

A field study was conducted in 2015 and 2016 Stoneville, MS, to evaluate the influence of cytokinin products on soybean injury weed control when combined with common POST herbicide treatments. Cytokinin treatments included no mixture two formulated mixtures (kinetin-1 kinetin-2) applied at 0.000227 kg ai ha−1. Herbicide were herbicide, glyphosate 1.37 ae ha−1 alone combination S-metolachlor 1.4...

Knockout and transgenic studies in mice demonstrate that normal somatic tissues redundantly express 3 cyclin D proteins, whereas tumor cells seem dependent on a single overexpressed cyclin D. Thus, selective suppression of the individual cyclin D deregulated in a tumor represents a biologically valid approach to targeted cancer therapy. In multiple myeloma, overexpression of 1 of the cyclin D p...

Callus growth and plant regeneration from long-term callus cultures were studied in two elite clones of Asparagus officinalis cv. Argenteuil, to establish a suitable protocol for a prospective in vitro selection program. Callus initiation and growth was evaluated on MS medium with 3% sucrose, 0.9% agar, 1 mg x l(-1) kinetin, and three levels of 2,4-D. The highest callus relative growth was obta...

With the aim of developing an efficient plant regeneration protocol, leaflet explants of three accessions of Arachis villosa Benth. (S2866, S2867 and L97) were cultured on basic Murashige and Skoog medium supplemented with different combinations of plant growth regulators: alpha-naphthalenacetic acid, indole-3-butyric acid, 6-benzylaminopurine, kinetin and thidiazuron. The accession L97 was the...
