The aim of this work was to assess the regeneration capacity of Amelanchier alnifolia var. cusickii and Lonicera kamtschatica cv. ‘Jugana’ from different types of explants under various hormonal treatments. The whole leaves, petioles, and internodal segments of in vitro plants were examined as explants. Several plant growth regulators (cytokinins and auxins) were evaluated for their ability to induce adventitious regeneration. Direct and indirect organogenesis was achieved under certain culture conditions in both species. The frequency of shoot regeneration was strongly dependent on concentrations of plant growth regulators in the induction media (L.kamtschatica ‘Jugana’) or concentrations of plant growth regulators in the induction media and type of explant (A. alnifolia var. cusickii). Results showed that leaves were not suitable explants for A. alnifolia var. cusickii. Both species were able to regenerate shoots from internodal segments and petioles. The highest induction of shoots was obtained on Murashige and Skoog (MS) medium enriched with 2 mg/L thidiazuron (TDZ) and 0.5 mg/L indole-3-butyric acid (IBA) for Amelanchier alnifolia and with 1 mg/L TDZ and 0.2 mg/L indole-3-acetic acid (IAA) for L. kamtschatica ‘Jugana’. Obtained adventitious shoots were further proliferated in order to investigate their multiplication capacity. The multiplication of shoots was successful in all cultivars, with the best results reported in A. alnifolia var. cusickii (7.07 shoots/explant on average).

Melia azedarach L. is one of the important plants because it’s a good source of natural compounds thathave insecticide and antimicrobial effect. The main aim of this research is to investigate the effect of explants source and plant growth regulators on in vitro callus induction and regeneration of organs from it. Callus was induced from nodes, internodes from one-year-old seedlings and seeds of Melia plant by culturing them on MS medium supplemented with α-naphthalene acetic acid (NAA) 0.0, 0.1, 0.2, 0.3, or 0.4 mg/L and 6- benzyl adenine (BA) 0.0, 1.0, 2.0, 3.0, or 4.0 mg/L, then shoot regeneration from callus was occurred. Results showed that there was a different response from explants towards callus induction and adventitious shoots formation according to plant growth regulators combination. Seeds gave superior percentage for callus induction 24.4% compared with node and internode 15.6, 12.8% respectively. Combination of 0.3 mg/L NAA + 3.0 mg/L BA was the best for callus induction in all explants 86.6% . Shoot regeneration was achieved in 0.3 mg/L NAA + 4.0 mg/L BA and 0.4 mg/L NAA + 4.0 mg/L BA for callus from seeds and internodes respectively, while the combination 0.3 mg/L NAA + 3.0 mg/L BA or 0.4 mg/L NAA + 3.0 mg/L BA was the best for node callus. The shoots were rooted well in MS + 0.25 mg/L NAA . Rooted plantlets were acclimatized in small plastic pots filled with peat moss: river soil (1 :1 v/v ), then transferred to the soil.

Indirect Organogenesis

Plant cell culture offers an alternative to whole plants for the production of biologically important specialised metabolites. In cultured plant cells, manipulation by auxin and cytokinin plant growth regulators (PGRs) may lead to in vitro organogenesis and metabolome changes. In this study, six different combination ratios of 2,4-dichlorophenoxyacetic acid (2,4-D) and benzylaminopurine (BAP) were investigated with the aim to induce indirect organogenesis from Bidens pilosa callus and to investigate the associated induced changes in the metabolomes of these calli. Phenotypic appearance of the calli and total phenolic contents of hydromethanolic extracts indicated underlying biochemical differences that were investigated using untargeted metabolomics, based on ultra-high-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UHPLC–qTOF–MS), combined with multivariate data analysis. The concentration and combination ratios of PGRs were shown to induce differential metabolic responses and, thus, distinct metabolomic profiles, dominated by chlorogenic acids consisting of caffeoyl- and feruloyl-derivatives of quinic acid. Although organogenesis was not achieved, the results demonstrate that exogenous application PGRs can be used to manipulate the metabolome of B. pilosa for in vitro production of specialised metabolites with purported pharmacological properties.

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.

Amygdalus Communis

The Almond (Amygdalus communis) is one of the most important and oldest commercial nut crops, belonging to the Rosaceae family. Almond has been used as base material in pharmaceutical, cosmetic, hygienically and food industry. Propagation by tissue culture technique is the most important one in woody plants. In the current research, in vitro optimization of tissue culture and mass production of almond was investigated. In this idea, explants of actively growing shoots were collected and sterilized, then transferred to MS medium with different concentrations and combinations of plant growth regulators. The experiment was done in completely randomized blocks design, with 7 treatment and 30 replications. After 4 weeks, calli induction, proliferation, shoot length and number of shoot per explants were measured. Results showed that the best medium for shoot initiation and proliferation was MS + 0.5 mg/l IAA (Indol-3-Acetic Acid) + 1 mg/l BA (Benzyl Adenine). Autumn was the best season for collecting explants. The shoots were transferred to root induction medium with different concentrations of plant growth regulators. The best root induction medium was MS + 0.5 mg/l IBA (Indol Butyric Acid).
