An experiment was performed to establish a regeneration protocol for an important medicinal plant, Asparagus racemosus. In the present investigation, nodal and internodal explants were employed for callus induction and axillary shoot formation. Maximum callus induction frequency was found on MS medium fortified with 2,4-D (1.0 mg/L) along with NAA (1.0 mg/L) and BAP (0.5 mg/L). However, individual effects of 2,4-D or NAA with BAP showed least callus induction. The higher concentrations of 2,4-D and BAP decreased the response of explants. However, maximum axillary shoot formation was observed on MS medium adjuvanted with BAP (2.0 mg/L) and NAA (0.5 mg/L).

In vitro study was carried out in an important medicinal plant Tinospora cordifolia (Willd.) Miers belonging to the family: Menispermaceae. Vegetative parts such as stem, leaf and nodal explants were excised from an elite in vivo grown mature plant and thereafter cultured on Murashige-Skoog (MS) medium supplemented with different hormonal concentrations for callus induction and organogenesis. Callus formation occurred from nodal segments, leaf and inter-node explants when planted on different combinations of hormones. Tinospora cordifolia showed response for in vitro shoot growth from the nodal segment. The best shoot growth was observed on MS medium supplemented with kinetin (1.5 mg/l). Similarly, the best result for root induction was obtained on MS medium supplemented with 6-benzylaminopurine (1.0 mg/l) and naphthaleneacetic acid (2.5 mg/l).

Indirect Regeneration

The medicinal plant, Aspilia africana, has been traditionally used in several African countries to treat many diseases such as tuberculosis, cough, inflammation, malaria, osteoporosis, and diabetes. In this study, we developed a protocol for in vitro propagation of A. africana using indirect shoot organogenesis from leaf and root explants of in vitro-grown seedlings and assessed the tissues at different developmental stages. The highest callus induction (91.9 ± 2.96%) from leaf explants was in the Murashige and Skoog (MS) medium augmented with 1.0 mg/L 6-Benzylaminopurine (BAP) and 1.0 mg/L 2,4-dichlorophenoxyacetic acid (2,4-D) while from root explants, the highest callus induction (92.6 ± 2.80%) was in the same plant tissue culture medium augmented with 0.5 mg/L BAP and 1.0 mg/L 2,4-D. The best shoot regeneration capacity from leaf-derived calli (i.e., 80.0 ± 6.23% regeneration percentage and 12.0 ± 6.23 shoots per callus) was obtained in medium augmented with 1.0 mg/L BAP and 0.05 mg/L α-Naphthaleneacetic acid (NAA); the best regeneration capacity for root-derived calli (i.e., 86.7 ± 6.24% shoot regeneration percentage and 14.7 ± 1.11 shoots per callus) was obtained in the MS medium augmented with 1.0 mg/L BAP, 0.05 mg/L NAA, and 0.1 mg/L Thidiazuron (TDZ). Regenerated plantlets developed a robust root system in 1/2 MS medium augmented with 0.1 mg/L NAA and had a survival rate of 93.6% at acclimatization. The in vitro regenerated stem tissue was fully differentiated, while the young leaf tissue consisted of largely unorganized and poorly differentiated cells with large intercellular airspaces typical of in vitro leaf tissues. Our study established a protocol for the indirect regeneration of A. africana and offers a basis for its domestication, large-scale multiplication, and germplasm preservation. To the best of our knowledge, this is the first study to develop an indirect regeneration protocol for A. africana and conduct anatomical assessment through the different stages of development from callus to a fully developed plantlet.

AbstractPluchea lanceolata is an important medicinal plant of Asteraceae family known for its anti-arthritic and anti-inflammatory activity. A protocol was established for micropropagation of P. lanceolata using nodal explants. Nodal explants were inoculated onto Murashige and Skoog (1962) - MS medium supple–mented with 6-benzylaminopurine (BAP), kinetin (Kin), thidiazuron (TDZ) and 2iP (2-isopentenyladenine) at various concentrations (0.0, 0.5, 1.0, 1.5 and 2.0 mg·dm-3). The highest multiplication rate was obtained for nodal explants cultured on MS medium, supplemented with 0.5 mg·dm-3 thidiazuron (TDZ). In vitro raised shoots were successfully rooted on ½ mineral salt concentration of MS medium supplemented with 1.0 mg dm-3 IBA.

Context: Mimosa pudica L. is an important medicinal plant belonging to the family- Mimosaceae has becoming a rare species in Bangladesh. The application of artificial seed technology using encapsulated shoot tips and nodal segments may contribute to the protection of rare and threatened medicinal plant like Mimosa pudica L.Objective: Synthetic seed technology has been developed for Mimosa pudica L. in order to develop an alternative protocol on propagation and conservation.Materials and Methods: For this purpose shoot tip and nodal segments obtained from in vitro grown plants were encapsulated with sodium alginate solution followed by subsequent immersion in CaCl2 solution. Different concentrations and combinations of growth regulators were used and explants were treated in alginate bead to investigate the hormonal effect on artificial seed germination. These encapsulated seeds were cultured either on MS medium with hormone (same growth regulators containing alginate beads) or MS0 (without hormone).Results: Highest shoot regeneration frequency (100%) were recorded when alginate beads were infused by MS medium supplemented with 2.0 mg/l BAP + 0.2 mg/l NAA and cultured in MS medium containing same growth regulators. When synthetic seed containing 2.0 mg/l BAP+0.2 mg/l NAA and cultured on MS0 medium, 54% explants produced multifarious root with shoot in both cases. Under different storage period encapsulated seed retained germination capacity even after preserving for 60 days at 4°C.Conclusion: For artificial seed production a suitable protocol established under this study for Mimosa pudica L. that provides an alternative method for micropropagation and its conservation. For long term storage of Mimosa pudica in Bangladesh this protocol would provide promising avenues for the easy transference of propagules and its improvement.J. bio-sci. 22: 89-99, 2014

Shoot Induction

Licorice plants, Glycyrrhiza glabra, G. uralensis, and G. inflata, were investigated for callus induction using Murashige and Skoog (MS) medium combined with auxins and cytokinins. After 4 weeks of culture, 33-100% of leaf or stem explants formed calli. Maximum of shoot induction from callus cultures was achieved by G. inflata stem explants cultured on MS medium supplemented with 1 mg/l α-naphthaleneacetic acid (NAA) and 0.5 mg/l 6-benzyladenine (BA) (67%) which also gave maximum shoot formation per explant (two shoots per explant). These results indicated that all three Glycyrrhiza species regenerated shoots from callus cultures on MS medium combined with NAA and BA or only thidiazuron (TDZ; 0.1 and 0.5 mg/l). Glycyrrhizin contents of G. uralensis calli induced using MS medium in combination with NAA and BA [(27.60 ± 8.47) μg/g DW] or TDZ alone [(36.52 ± 2.45) μg/ g DW] were higher than those found in other combinations.

Haploid Plants

To observe the possibility of producing haploid plants of Chrysanthemum, anthers of three Korean cultivars ‘Yes Morning’, ‘Hi-Maya’, and pot cultivar ‘Peace Pink’ were cultured. Callus induction among cultivars differed little, but equally good results were obtained with the basal MS medium supplemented with 1 mg/L of 2,4-D, 2 mg/L of BA, 250 mg/L of casein hydrolysate, 45 g/L of sucrose; solidified by 2.75 g/L gelrite. A pretreatment of anthers in media at 4 °C for 48h enhanced the callus induction. Calli were allowed to differentiate on basal MS medium supplemented with 2 mg/L of BA, 0.1 mg/L of NAA, 30 g/L of sucrose; solidified by 2.75 g/L gelrite.  Shoot formation from calli in that media slightly differed among cultivars. Multiple shoots elongated from calli were shifted to basal MS medium supplemented with 0.1 mg/L of NAA, 30 g/L of sucrose; solidified by 3 g/L gelrite for rooting. The plantlets with sufficient roots thus obtained were acclimatized and transferred to the soil. Fifty regenerated plantlets from each cultivar were randomly selected for ploidy observation by chromosome counting and haploid plantlet was detected for the garden cultivar ‘Yes morning’.
