Pueraria Candollei

Pueraria candollei Wall. ex Benth. var. mirifica (Airy Shaw & Suvat.) Niyomdham was investigated for callus induction using Murashige and Skoog (MS) medium containing different plant growth regulators. After 8 weeks of culture, 66 - 100% of leaf or stem explants formed calli. Calli from stem explants cultured on MS medium supplemented with 0.5 mg/l thidiazuron (TDZ) gave the maximum of shoot induction (16%) and the highest level of total isoflavonoids [(50.39 ± 7.06) mg/g dry wt], which was 7-fold higher than that of the native tuber [(7.04 ± 0.29) mg/g dry wt]. These results suggest that addition of TDZ to the culture medium markedly enhances the production of isoflavonoids in calli induced from stem explants of P. candollei var. mirifica.

AbstractMelia azedarach L. is a valuable source of antioxidants and secondary metabolites. This study is a first extensive report about the effect of different serialization protocols and plant growth regulators (PGRs) on explant disinfection efficiency, callus induction and secondary metabolites production and accumulation in callus cultures of M. azedarach L. In this regard, the effect of plant growth regulators on callus induction and secondary metabolites production were examined. In addition, different sterilization agents were evaluated for disinfection of chinaberry leaf explants. The results showed that the lowest percentage of explant contamination and browning with the highest percentage of callus induction and callus growth obtained with explants pretreated with benomyl (2 g/L) for 2 h and sterilized with 7% H2O2 for 10 min and NaOCl 2% (without pH adjustment) for 12 min. Although adjusting the pH of NaOCl to pH  = 7 and 10 significantly reduced the microbial contamination and increased the percentage of contamination-free cultures of M. azedarach L., adversely influenced the explant viability and callus induction and growth. The highest percentage of callus induction obtained on the MS medium containing 3 mg/L NAA/2,4-D and 1 or 3 mg/L Kin/BAP, and the highest callus yield (1804.833 mg/explant) belonged to the MS medium supplemented with 5 mg/L 2,4-D and 5 mg/L Kin. The callus cultures grown on the MS medium supplemented with 3 mg/L NAA and 1 mg/L Kin produced the highest amount of Quercetin (2.06 mg/g fresh weight), Rutin (5.56 mg/g fresh weight) and Kaempferol (1.84 mg/g fresh weight).

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.

Trachyspermum Copticum

The effect of explant sources and plant growth regulators on callus induction and plantlet regeneration of Trachyspermum copticum were explored. Different explants including hypocotyl, cotyledonary node and leaf were cultured on MS supplemented with different combinations and concentrations of plant growth regulators including 2,4‐D (0.2‐3 0.5 mg/l), NAA (2 mg/l), BAP (1‐3 mg/l), Kn (0.5 mg/l) and IAA (0.8 mg/l). The best response for callus induction (100%) as well as quality was observed from cotyldonary node segments cultured on MS supplemented with 2, 4‐D at 1 mg/l in combination with Kn at 0.5 mg/l. Calli derived from various explants were subcultured on shoot induction media with different compositions and concentrations of medium. MS without any plant growth regulator promoted the highest frequency of shoot regeneration (100%) and also mean number of developed shoots per explants (3.8) showed the same result. Regenerated shoots were then rooted on three‐fourth strength MS with 75% efficiency after 30 days.Plant Tissue Cult. & Biotech. 27(1): 13-20, 2017 (June)

Plant growth regulators were used to test callus induction and in vitro regeneration in six rice genotypes (RM-AC-2, BRRI dhan89, BRRI dhan88, Nipponbare, Koshihikari and Zenshan97). Four different concentrations (1, 2, 3 and 4 mg/L) of 2,4-D for callus induction and three different concentrations (1,2 and 3 mg/L) of NAA with three doses (5,10 and 15 µ/L) of kinetin for callus regeneration were used to test the effect of plant growth regulators. This study found a high callus induction on MS medium enriched with 2 mg/L 2, 4-D. In cases of RM-AC-2, BRRI dhan89, BRRI dhan88, Nipponbare, Koshihikari and Zenshan97, callus induction frequencies were 92.7%, 87.8%, 84.6%, 82.9%, 86.2% and 62.9%, respectively. In the regeneration, it was found that an MS medium enriched with 2 g/L Kinetin and 10 µm/L NAA has the ability to induce increased regeneration of different rice varieties (RM-AC-2 (72.4%), BRRI dhan89 (66.9%), BRRI dhan88 (62.5%), Nipponbare (63.3%), Koshihikari (48%) and Zenshan97 (39.6%). From the regenerated plants, one plant of the RM-AC-2 genotype availed to complete its life cycle and generated 32 effective tillers and yielded 89g. This rice plant is very promising for high yielding rice variety development program in Bangladesh. The improved callus development and regeneration ability of this genotype might be helpful for future rice variety development and genetic transformation program.

Bud Induction

An efficient in vitro method for multiple shoot bud induction and regeneration has been developed in Artemisia annua L. using leaf and stem explants in various concentrations and combinations of plant growth regulators to evaluate the frequency of regeneration. The sources of explants as well as plant growth regulators in the medium were found to influence the multiple shoot induction. The result shows that the stem segment cultured on Murashige and Skoog (MS) medium supplemented with 0.1 mg/l thidiazuron (TDZ) gave a perfect shoot formation (100%) and good shoot multiplication (57 shoots/explant) after 2 weeks of culture. Healthy regenerated shoots were elongated and rooted in MS medium without hormones. The artemisinin content in plants regenerated from stem explants using 0.1 mg/l TDZ was (3.36 ± 0.36) μg/mg dry weight and two-fold higher than that of in vitro grown plants of the same age [(1.73 ± 0.23) μg/mg DW]. This system exhibited a potential for a rapid propagation of shoots from the stem explant and makes it possible to develop a clonal propagation of A. annua.

On the MS medium containing only 2,4-D, callus induction was inhibited. Moreover, these calli were friable and turned brown after two weeks of culture. the three-week old calli were then transferred to the MS medium containing NAA 0.5 mg/l and kinetin 1 mg/l. The somatic embryos with globular shape appeared after 10 days of culture, while the heart shape, torpedo_shape and cotyledonary_shape embryos appeared successively after 15 days of culture. The abnormal embryos occupied at a rate of 34.3% and rarely germinated to plantlets. On the MS medium without plant growth regulators or only with NAA, somatic embryos could not be induced. On MS medium supplemented with ethephon 3 mg/l somatic embryogenesis from calli was inhibited. Plantlets derived from the eggplant somatic embryos had a survival rate up to 95% when transferred to the pots.

Ginger (Zingiber officinale Roscoe) var. Bentong is a monocotyledon plant that belongs to the Zingiberaceae family. Bentong ginger is the most popular cultivar of ginger in Malaysia, which is conventionally propagated by its rhizome. As its rhizomes are the economic part of the plant, the allocation of a large amount of rhizomes as planting materials increases agricultural input cost. Simultaneously, the rhizomes’ availability as planting materials is restricted due to the high demand for fresh rhizomes in the market. Moreover, ginger propagation using its rhizome is accompanied by several types of soil-borne diseases. Plant tissue culture techniques have been applied to produce disease-free planting materials of ginger to overcome these problems. Hence, the in vitro-induced microrhizomes are considered as alternative disease-free planting materials for ginger cultivation. On the other hand, Bentong ginger has not been studied for its microrhizome induction. Therefore, this study was conducted to optimize sucrose and plant growth regulators (PGRs) for its microrhizome induction. Microrhizomes were successfully induced in Murashige and Skoog (MS) medium supplemented with a high sucrose concentration (>45 g L−1). In addition, zeatin at 5–10 µM was found more effective for microrhizome induction than 6-benzylaminopurine (BAP) at a similar concentration. The addition of 7.5 µM 1-naphthaleneacetic acid (NAA) further enhanced microrhizome formation and reduced sucrose’s required dose that needs to be supplied for efficient microrhizome formation. MS medium supplemented with 60 g L−1 sucrose, 10 µM zeatin and 7.5 µM NAA was the optimum combination for the microrhizome induction of Bentong ginger. The in vitro-induced microrhizomes sprouted indoors in moist sand and all the sprouted microrhizomes were successfully established in field conditions. In conclusion, in vitro microrhizomes can be used as disease-free planting materials for the commercial cultivation of Bentong ginger.
