Stevia rebaudiana Bertoni that conventionally propagated by seed or by cuttings or clump division which has a limitation of quality and quantity seed material. In present study, callus culture technique was tried to achieve rapid plant multiplication for quality seed material. Callus induction and multiplication medium was standardized from nodal as well as leaf sagments. It is possible to main...

The gesneriaceous perennial plant, Lysionotus serratus, has been used in traditional Chinese medicine. It also has a great development potential as an ornamental plant with its attractive foliage and beautiful flowers. An efficient propagation and regeneration system via direct shoot organogenesis from leaf explant was established in this study. High active cytokinin (6-benzyladenine (BA) or th...

Sugarcane breeding under climatic conditions of Pakistan is very difficult due to unavailability of viable fuzz (seed). Somaclonal variation can provide an alternative for improvement of existing genotypes. Six hundred and twenty-seven somaclones were developed from sugarcane genotype S97US297, and protocols for callogenesis and organogenesis were developed using Murashige and Skoog medium...

The induction and improvement of in vitro rhizogenesis of microshoots of Prosopis chilensis (Mol.) Stuntz and Nothofagus alpina (Poep. et Endl. Oerst.) were compared using Agrobacterium rhizogenes (Ar) versus indole-3-butyric acid (IBA) in the culture media. Microshoots of P. chilensis (1-2 cm length), coming from in vitro grown seedlings, were cultivated in a modified Broadleaved Tree Medium (...

Stabilized shoot cultures initiated from crown material of six adult Quercus robur L. trees and from basal epicormic shoots of a Quercus rubra L. tree showed good in vitro rooting capacity. An initial five-day dark period generally improved the rooting response but was detrimental to plantlet quality. There were clonal differences in rooting capacity. The concentration and exposure time of the ...

Withania somnifera (L.) Dunal is high demanding valuable medicinal plants which have pharmaceuticals properties, known for its with anolides. Nodal segment explants of W. somnifera when cultured on MS (Murashige and skoog’s, 1969) medium horizontally containing different concentration(1-3mg/l) of 6-benzylaminopurine (BAP), kinetin (Kn) and thidiazuron (TDZ) produced multiple shoots on both axil...

The homosporous fern Ceratopteris richardii exhibits a homorhizic root system where roots originate from the shoot system. These shoot-borne roots form lateral roots (LRs) that arise from the endodermis adjacent to the xylem poles, which is in contrast to flowering plants where LR formation arises from cell division in the pericycle. A detailed study of the fifth shoot-borne root showed that on...

In vitro-derived cultures of plants offer a great potential for rapid biosynthesis of chemical-free antimicrobial silver nanoparticles (AgNPs) by enhancing their phytochemical reducing potential. Here, we developed an efficient protocol for in vitro micropropagation of a high-value endangered medicinal plant species, Phlomis bracteosa, in order to explore its biogenic potential in biomimetic sy...

Cell culture in shake flask and air-lift bioreactor was carried out to exploit the potential of Arnebia sp. for napthoquinone metabolite production. Cell suspension cultures of Arnebia were established from friable callus in liquid MS medium supplemented with 6-benzylaminopurine (BAP) (10 μM) and indole-3-butyric acid (IBA) (5 μM). Growth kinetic studies were done by using settled cell volume a...

Andrographis lineata Nees (Acanthaceae) is an endemic herb rich in flavonoids and diterpenoids which have pharmaceutical importance. Seedling explants source has not been studied for micropropagation and hence the present investigation has been taken up. An efficient protocol was developed for aseptic seed germination and in vitro shoot multiplication from different aseptic seedling explants. 3...
