The morphogenic potential and free-radical scavenging activity of the medicinal plant, Silybum marianum L. (milk thistle) were investigated. Direct root regeneration and indirect organogenesis and preliminary phytochemical, antibacterial studies of its callus. From leaf explants the highly significance result was found on the NAA at 2 mg/l and KIN at 0.2 mg/l for the direct root induction and i...

In addition to traditional methods, advanced biotechnologies, especially CRISPR/Cas9-mediated genome editing, have emerged as effective tools for improving important agronomic traits in rice. However, the critical step utilizing these systems is develope an system rice transformation and regeneration. This study was performed establish procedures Agrobacterium-mediated regeneration of cultivar ...

Chicory (Cichorium intybus L.) is a low-height perennial or biennial herb from the family of Asteraceae. Investigation different in vitro regeneration strategies Cichorium and increasing number secondary metabolites regenerated plant samples were aims research. Callus regenerations achieved basal growth media supplemented with regulators (PGRs). Whole was carried out by direct organogenesis lea...

OBJECTIVES Locked plating constructs may be too stiff to reliably promote secondary bone healing. This study used a novel imaging technique to quantify periosteal callus formation of distal femur fractures stabilized with locking plates. It investigated the effects of cortex-to-plate distance, bridging span, and implant material on periosteal callus formation. DESIGN Retrospective cohort stud...

In vitro propagation of C. morifolium cv. ‘Homa’ and cv. ‘Delkash’ and wild C. coccineum via direct and indirect organogenesis and somatic embryogenesis were investigated. BAP at 0, 1, 2 and 3 mg l-1 or NAA at 0, 0.05, 0.1 and 0.2 mg l-1 concentrations were used to induce direct and indirect organogenesis of shoot tip explants. To study the callu...

By using shoot tips as explants, various media and culture conditions for callus induction and proliferation, shoot differentiation, root induction and plantlet transplantation to develop an efficient and reliable regeneration system with Dendrocalamus hamiltonii were tested. Murashige and Skoog (MS) medium supplemented with 3 mg/l 2, 4-dichlorophenoxyacetic acid, 1 mg/l benzyladenine (BA), 500...

Pith tissue from Nicotiana tabacum L. cv ;Maryland Mammoth' or ;Wisconsin 38' was isolated, free of vascular tissue, and cultured on a medium containing auxin but no cytokinin. Explants from the apical 1 cm of stem, within the pith rib meristem, initiated callus growth with 100% efficiency. Macroscopically visible callus was evident 5 days after the tissue was isolated, and the cultures grew pe...

Vitamins are necessary compounds synthesized and utilized in plants. In tissue culture media, vitamin addition is not always common; since the amount needed by plants is relatively unknown and varies. Vitamins, in combination with other media constituents, have been shown to have direct and indirect effects on callus growth, somatic growth, rooting, and embryonic development. For example, diffe...

Friable callus was initiated from shoot apices of Gloriosa superba L. on basal MS medium supplemented with 2, 4-D (4mg L(-1)) + Kn(5 mg L(-1)) + CH(10 mg L(-1)) + CW(20%). Subculture of callus on the same medium after 4-5 weeks showed induction of large number of somatic embryos, which was confirmed with histological studies. Development of embryoids in plantlet took place when the embryogenic ...
