Chinese fever vine (Paederia foetida L.), a valuable medicinal plant has been greatly utilized in therapeutic purposes throughout the world. Since conventional propagation techniques of P. foetida are very slow, inefficient and cannot cope with the increasing demand, in-vitro regeneration through tissue culture could be an alternative means of rapid propagation. Therefore, the efforts were made to develop a suitable protocol through direct organogenesis of P. foetida. After surface sterilization, the nodal explants were cultured in Murashigue and Skoog (MS) medium and MS medium supplemented with different concentrations and combinations of plant growth regulators. MS medium supplemented with 6-benzylaminopurine; BAP (2.0 mg L-1) produced the maximum number of shoots; 4.40 ± 0.98 and 5.40±1.12 after 15 and 30 days of culture respectively. The number of shoots gained by 15 days was found to be the highest; 1.20±0.80 at BAP (4.0 mg L-1) followed by 1.00±0.55 at BAP (2.0 mg L-1). Although the combination of BAP + Kinetin (2 mg L-1 +2 mg L-1) showed the highest shoot growth (3.40 ± 1.08 cm) by 15 days, sole application of BAP (2.0 mg L-1) or Kn (0.5, 1.0, 2.0 and 3.0 mg L-1) showed similar responses. BAP (2.0 mg L-1) showed the best responses for developing the highest number of leaves; 18.60 ± 2.42 and 29.20 ± 2.73 respectively after 15 and 30 days of culture. Similarly, development of the maximum number of leaves (10.60 ± 0.68) was reported by 15 days at BAP (2.0 mg L-1). Rooting was significantly induced in indole-3-acetic acid (IAA) supplemented to 1/2 strength MS medium as compared to control (only ½ strength MS medium). The best performance of rooting was observed by 0.5 mg L-1 IAA which produced average 4.33 roots per shoot after 21 days of culture. The regenerated plants showed similar morphology to the mother plants. Thus, a suitable protocol for successful multiplication of P. foetida in vitro was established using nodal explants. Ann.

The objective of this work was to study the histological events related to the regeneration process of a medicinal plant, Nymphoides cristatum (Roxb). Leaf explants were cultured on MS medium supplemented with 0.5 mgl-1 of 6-benzyl amino purine (BAP). About 90% of explants gave rise to shoots after 15 days of incubation. The histological studies showed that the regeneration originated directly from parenchymatous cells and direct organogenesis after 20 days of culture could be observed. Buds and roots were found completely differentiated after 40 days of culture and number of shoots per explants was 30. Micorshoots were rooted in hormone - free medium and the plants obtained grew in artificial pond under green house conditions.

An efficient high frequency plant regeneration protocol through direct organogenesis was developed for Sevia rebaudiana. Shoot tips containing axillary buds were used as an explant and inoculated on Murashige and Skoog’s (MS) medium containing 3% (w/v) sucrose, 0.6% (w/v) agar supplemented with various concentrations of benzy-ladenine (BA), kinetin (Kn) and thidiazuron (TDZ).. BAP proved to be a better choice than Kn and the maximum number of shoots (3.75) was obtained on 2.0 mgL-1 BAP concentration. Considering all parameters, combination of BAP and Kn gave comparatively better performance than single BAP or Kn. TDZ was effective for multiple shooting. Though, 1.5 mgL-1 TDZ gave the best number of shoots (14.5), but 1.0 mgL-1 TDZ gave best performance in response to all parameters under study. The highest number of shoots was obtained in 60 mlL-1 coconut water, but 40 mlL-1 coconut water gave the best result to all parameters. Root induction was tested by using two auxins namely NAA and IBA at different concentrations (1.0, 1.5, 2.0 mgL-1) on the MS medium. IBA at 1.0 mgL-1 increased the rooting response (66.67%), number of roots (7.0) and root length (2.9 cm). Higher concentration of IBA and NAA (2.0 mgL-1) showed poor results of rooting response (33.33%).Asian J. Med. Biol. Res. March 2016, 2(1): 95-106

An experiment was conducted on in vitro regeneration and multiplication of Dendrobium bensoniae. Different concentrations of BA and IBA alone or combination of both hormones were used as treatment for regeneration.  It was revealed that shoot regeneration from node was the best at 2.0 mg/l BA supplemented to MS medium. It gave better responses than all other concentrations and combinations of BA and BA+IBA, used in the present study. The highest number of shoots and leaves were found when 1.0 mg/l BA with 1.5 mg/l IBA was supplemented into MS medium.  For rooting, 0.5 mg/l BA with 1.0 mg/l IBA was found to be the most effective. The well-rooted plantlets were successfully acclimatized under 70-80% humidity and planted in pots and transferred to the shade house for establishment. Around 85% of plantlets survived in the field. From the present result, it may be recommended that MS medium supplemented with 2.0 mg/l BA may be used for rapid shoot induction and regeneration of D. bensoniae.The Agriculturists 2016; 14(2) 24-31

An efficient in vitro regeneration system was developed for Rauvolfia serpentina L. through direct and indirect organogenesis from nodal and leaf explants. Among the different growth regulators, MS medium supplemented with 2.0 mg/l BAP, 0.5mg/l IAA and 0.02mg/l NAA found best for the multiple shoot formation from nodal segments. In this combination 98% explants produced multiple shoots and the average number of shoots per explants is 13∙4. The frequency of callus induction and multiple shoot induction from leaves was highest 88% in MS medium supplemented with 2.0 mg/l BAP, where mean number of shoots/explants was 12.5. The highest frequency of root induction (80%) and mean number of roots/plantlets (10) were obtained on half strength of MS medium containing 0.2 mg/l IBA. The rooted plantlets were transferred for hardening following acclimatization and finally were successfully established in the field.Bangladesh J. Sci. Ind. Res.53(2), 133-138, 2018

In this present work, an in-vitro regeneration protocol for Crescentia alata (C. alata) was developed using various explants on Murashige and Skoog (MS) medium augmented with different concentrations and combinations of plant growth regulators (PGRs) for direct and indirect regeneration. The direct organogenesis was established from nodes and internodes on MS medium supplemented with cytokinins and auxins. The indirect organogenesis via callus phase was obtained from leaf, nodes and internodes on MS medium supplemented with different concentrations of PGRs. The high frequency shoot organogenesis were achieved directly from nodal explants were cultured on MS medium supplemented with 3.0 mg/L BAP+0.5 mg/L KIN +1.0 mg/L NAA. Indirect organogenesis callogenic frequency was optimized at the concentration of MS medium containing 1.0 mg/L BAP + 5.0 mg/L IAA. The callus was obtained from all the explants were used, among these explants internodal explants gave best result on MS medium supplemented with different concentrations of cytokinins and auxins for indirect organogenesis experiment. Indirect organogenesis the highest number of shoot regeneration was obtained in MS Basal Medium with 4.0 mg/L BAP + 0.5 mg/L KIN + 2.0 mg/L NAA from internodal explants. For root formation the regenerative shoots which were sub cultured on MS medium containing different ratios of auxins. The rooted plantlets were transferred successfully to the pots containing sterilized soil and were successfully hardened at greenhouse condition for 20 days then exposed to the natural environment. This is the first successful micropropagation report of an efficient and rapid in-vitro clonal propagation protocol for C. alata by direct and indirect shoot organogenesis through various explants, which can be employed for conservation of this important medicinal tree species as well as the utilization of an biologically important active biomolecules. This protocol can be very useful to obtain plants from various explants, without the requirement of meristematic regions, enabling the obtainment of a higher number of plants in short period.

Abstract Background: As a highly valued medicinal plant, Salvia plebeia R. Brown belongs to the Lamiaceae family that has been subjected to over exploitation in its natural habitat for phytochemical and pharmacological studies. Alternative collection methods need to be developed for the large-scale propagation of Salvia plebeian. Results: Here, efficient and simple, direct organogenesis (from shoot tips and cotyledonary nodes explants) and Globular bodies (GBs) induction (from hypocotyl explants) systems were developed for the in vitro propagation of Salvia plebeia. The highest and number of regenerated shoots (7.0±0.82) per shoot tips was obtained on Murashige and Skoog (MS) medium supplemented with a combination of 0.1 mg L-1 indole-3-acetic acid (IAA) and 1.0 mg L-1 6-benzyladenine (6-BA), the proliferation of shoots and shoots rooted were carried out on the same medium treatments almost synchronously. Similarly, MS medium supplemented with 0.1 mg L-1 IAA and 1.0 mg L-1 thidiazuron (TDZ) yielded the maximum number of shoots (37.5±1.34) with 100% shoot sprouting frequency. Simultaneously, a protocol was developed for GBs induction from hypocotyl explants, and it produced 17.4 GBs per explant with 82.7% response on MS medium supplemented with TDZ (1.0 mg L-1) and IAA (0.1 mg L-1), and produced GBs that were morphologically similar to globular embryos and successfully germinated on hormone-free MS medium. The acclimatized plantlets with well-developed root systems were successfully shifted to the natural soils with a 100% survival rate. Conclusions: Taken together, this protocol can be efficiently used for mass propagation, germplasm preservation and likely also for gene transfer of Salvia plebeia.

Passiflora miniata is a wild species native to the Southern Amazon, with ornamental potential due to the beauty of its flowers of intense red coloration. Reports in the literature about the species are still insipid. The aim of the present study was to induce the regeneration of P. miniata by the de novo organogenesis from mature zygotic embryos. The zygotic embryos were isolated and cultivated into the MS medium with the addition of 6-Benzyladenine (BA), Thidiazuron (TDZ) and Kinetin (KIN) growth regulators. The de novo regeneration from the zygotic embryos occurred directly and indirectly. A percentage of 80% of the explants cultivated in the presence of BA had direct organogenesis and 20% by the indirect way, with TDZ 60% were regenerated by the direct and 40% by the indirect way. Regarding the treatments with KIN, 58% of the explants had regeneration by direct and 42% by the indirect organogenesis. The development of shoot primordia initiated with the formation of organogenic structures that later differentiated into multi-shoots. The highest mean number of shoots (40.0 shoots per explants) was obtained on 0.75 mg L-1BA. Conversely, using 0.50 mg L-1 TDZ or KIN, the highest number of shoots were 7.2 and 3.6, respectively.
