Harmful Effects

In general, in vitro virus elimination is based on the culture of isolated meristem, and in addition thermotherapy, chemotherapy, electrotherapy, and cryotherapy can also be applied. During these processes, plantlets suffer several stresses, which can result in low rate of survival, inhibited growth, incomplete development, or abnormal morphology. Even though the in vitro cultures survive the treatment, further development can be inhibited; thus, regeneration capacity of treated in vitro shoots or explants play also an important role in successful virus elimination. Sensitivity of genotypes to treatments is very different, and the rate of destruction largely depends on the physiological condition of plants as well. Exposure time of treatments affects the rate of damage in almost every therapy. Other factors such as temperature, illumination (thermotherapy), type and concentration of applied chemicals (chemo- and cryotherapy), and electric current intensity (electrotherapy) also may have a great impact on the rate of damage. However, there are several ways to decrease the harmful effect of treatments. This review summarizes the harmful effects of virus elimination treatments applied on tissue cultures reported in the literature. The aim of this review is to expound the solutions that can be used to mitigate phytotoxic and other adverse effects in practice.

In Vitro Shoot Cultures

The aim of this study was to evaluate the composition of aqueous extracts of in vitro shoot cultures and wild plants of Pterospartum tridentatum in order to promote the use of this plant material as a possible source of bioactive compounds. The extraction yield from wild plants compared with in vitro shoot cultures was lower. The total phenolic contents of in vitro shoots were significantly lower compared with those of wild plants. The phenolic profiles of in vitro shoots were very similar to those of wild plants, regardless of the source. However, taxifolin-6- C-glucoside, as well as rutin and isoquercitrin, were not present in extracts of in vitro shoots. An interesting result was the higher molar percentages of rhamnose and uronic acids detected in in vitro shoots compared with the wild plants, which can make the in vitro plant material very useful for obtaining these compounds.

To evaluate an efficient protocol for the micropropagation of Tupistra albiflora K. Larsen, the effects of N6-benzylaminopurine (BA) and naphthalene acetic acid (NAA) concentrations on multiple shoot and root induction were examined. In vitro shoots were used as the explant materials which were cultured on Murashige and Skoog (MS) agar medium supplemented with 0, 1, 2, 3 and 4 mg/L BA for 4 weeks to induce multiple shoots. It was found that the MS medium containing 3 mg/L BA induced 100 % shoot formation with the highest number of 3.2 shoots per explant (2.4-fold significantly higher than the control). For root induction, in vitro shoots were cultured on MS agar medium supplemented with 0, 1, 2, 3 and 4 mg/L NAA for 8 weeks. The results showed that the MS medium containing 1 mg/L NAA induced 100 % root formation with the highest number of 6.6 roots per explant (1.8-fold significantly higher than the control).

Objective: The important restraints in plant-derived medicine are the convenience of active composites which depends on diverse topographical situations, active compound build-up pattern, environmental circumstances and genetic makeup of the plant. The presented work was aimed to describe an efficient technique for fast propagation of Nothapodytes nimmoniana which is an imperative source of Camptothecin.Methods: Multiple shoots were successfully regenerated from the explants N. nimmoniana using Murashige and Skoog (MS) medium accompanied with IBA+KN+GA3 (1:3:2) mg/l. the hydro-alcoholic extract was obtained by soxhlet extraction for field grown roots (fgRE), shoots (fgSE) and in vitro plantlets (ivPL) and further subjected to phytochemicals analysis. HPLC analysis was performed to determine the percentage of camptothecin (CAM). Anti-proliferative studies were carried out followed by Acridine orange/Ethidium bromide staining. Extracts were also estimated for reactive nitrogen species (RNS) and reactive oxygen species (ROS).Results: Preliminary qualitative chemical analysis of the extracts displayed the presence of alkaloids, carbohydrates, steroids, saponins, terpenoids and phenolics compounds. HPLC analysis revealed the presence of CAM in all the extracts. ivPL exhibited lowest anti-proliferative activity in contrast to other extract and percentage of ROS and RNS was also less. Although ivPL did not exhibited prominent anti-tumour effect, but in vitro accumulation of CAM in 2-months old shoots provides an alternative resource to 5 y-old field grown plants.Conclusion: This work delivers a potential to lead to further increase the potency of CAM in in vitro shoots of two months old as an alternative to the field grown plants for treating cancers.

Phyllocladane diterpenoids, particularly calliterpenone (1) and calliterpenone monoacetate (2), isolated from leaves of Callicarpa macrophylla, produced significantly higher growth and multiplication of in vitro shoot cultures of Rauwolfia serpentina at 0.25 and 0.5 mg/L concentrations, respectively, compared to certain other plant growth regulators (0.1-5.0 mg/L) tested under in vitro conditions. This is the first report of the plant growth promoting activities of 1 and 2 in plant tissue cultures.

The aim of our study was to investigate the presence and quantitative contents of lignans in the tissues of <em>Taxus</em> ×<em>media</em>. The presence of the lignans: pinoresinol, matairesinol and secoisolariciresinol was assessed in needles, shoots cultures and suspension culture. Pinoresinol was the only lignan found in the tissue of <em>T.</em> ×<em>media</em>. The total pinoresinol content in the needles and in the shoots was 1.24 mg/g dry weight (dw) and 0.69 mg/g dw, respectively. Most of the pinoresinol identified was appeared glycosidically bound. In needles, the amount of glycosidically bound pinoresinol (0.81 mg/g dw) was about twice as high as that of free pinoresinol (0.43 mg/g dw). The content of free and glycosidically bound pinoresinol showed the level of 0.18 mg/g dw and 0.51 mg/g dw, respectively in the in vitro shoot cultures. In the cell culture, no pinoresinol was found.
