Artemisia Annua L

Artemisinin, an important antimalarial drug against multidrug resistant strains of Plasmodium, can be produced in Artemisia annua L. Field production of artemisinin is affected by environmental condition and geographical location. In vitro production via cell suspension culture is an alternative mode and cell line selection is important to ensure sustainable production of biomass and artemisinin. Callus cell lines were derived from the leaf explants of five A. annua clones grown in two different locations in Vietnam. Thirty-four callus cell lines with consistent growth index (GI) were selected from these five clones and were categorized into fast (GI > 20), intermediate (GI 15 - 20) and slow (GI < 15) growing groups. The selected lines were found to have different morphology in term of colour and texture. The callus texture did affect the cell growth of A. annua in which the friable callus type showed faster, consistent and sustainable cell biomass production.D. O.

The objective of this study was to establish cell suspension culture and plant regeneration via somatic embryogenesis of a Brazilian plantain, cultivar Terra Maranhão, AAB. Immature male flowers were used as explant source for generating highly embryogenic cultures 45 days after inoculation, which were used for establishment of cell suspension culture and multiplication of secondary somatic embryos. Five semisolid culture media were tested for differentiation, maturation, somatic embryos germination and for plant regeneration. An average of 558 plants per one milliliter of 5% SCV (settled cell volume) were regenerated in the MS medium, with 11.4 µM indolacetic acid and 2.2 µM 6-benzylaminopurine. Regenerated plants showed a normal development, and no visible somaclonal variation was observed in vitro. It is possible to regenerate plants from cell suspensions of plantain banana cultivar Terra using MS medium supplemented with 11.4 µM of IAA and 2.2 µM of BAP.

Aquilaria Malaccensis

Aquilaria malaccensis Lam. is a plant species producing fragrant woody material that contains some resin. The compounds can be used as medicine and perfume. Sesquiterpenoid, one group of compounds has been found being synthesized and subsequently extracted from callus and cell suspension culture of Aquilaria species. The aim of this research was to find a method of producing friable calli and cell suspension cultures from leaves or internodes of A. malaccensis in vitro by using suitable plant growth regulators; cell suspension that will suitably serve as material to produce sesquiterpenoid afterwards. Calli were established in almost all treatments of auxin-cytokinin on both leaves and internod explants. The treatment of 10 mg/L IBA induced the highest percentage of callus coverage from leaves with a rather compact structure. The combined treatment of 1–2 mg/L 2.4-D and 0.2–0.3 mg/L BA induced friable callus formation in more than 80% of cultures with 27–32% callus coverage percentage.  The use of 2,4-D induced a better formation of cell suspension than Picloram, with maximum volume up to 7 mL. Cell suspension culture with fine and homogenous aggregate could be established in the medium supplemented with 0.5 –1 mg/L 2,4-D.

<p>An attempt was made to establish highly competent embryogenic cell suspension culture in coconut, a species recalcitrant to in vitro culture. Embryogenic calli were initiated from shoot meristem explants of coconut. Y3 medium supplemented with 2.4-D (4.5 μM) and glutamine (34.2 μM) was found to be the best medium to initiate cell suspension. Growth evaluation was done by packed cell volume (PCV) and it was found that maximum growth volume of 9.9% was reached at 200 days of culture initiation. About 52% of viable cells were detected through fluorescent microscopy. Cell aggregation was noticed in Y3 medium supplemented with glutamine (34.2 μM), malt extract (100mg/l), biotin (40.9 μM) and kinetin (9.3 μM), but further progress could not be achieved. It was also observed that embryogenic calli were not of a friable type, but were associated with densely aggregated cells. Because of its hard nature, we were unsuccessful to obtain high quality cell suspension.</p>
