“…Photosynthetic pigments are one of the main components of the photosynthesis mechanism (Mishra et al, 2007;Stewart and Globig, 2016) and any change in their amount and structures (Meier et al 2011) will destroy this mechanism (Doganlar, 2012), and disturb the morphological, physiological and biochemical reactions (Wieczorek and Wieczorek, 2007). On the other hand, since there is a positive correlation between photosynthetic pigment and EO amounts (Batista et al,2016), and the inhibition of chlorophyll production by heavy metal stress leads to a significant decrease in metabolite production (Okem et al, 2015). Therefore, chlorophyll degretation is an important indicator used for determining the effects of various stress factors on plants (Aiamla-or et al, 2010).…”

Abstract. Secondary metabolites, which have an important role in regulating plants' relationship with the environment, are affected by soil pollution. Thus, it is important to describe the mechanism in which lemon balm's (Melissa officinalis L. subsp. officinalis) secondary metabolite accumulation is affected by Cadmium (Cd) stress. For this purpose, lemon balms seedlings that were grown in a controlled environment were exposed to increasing Cd stress and the relationship of lemon balm's growth and development with EO (essential oil) accumulation were investigated. Morphological, anatomical and physiological parameters of plants' that were exposed to Cd significantly decreased in parallel with increasing Cd concentration. Impairments in growth and development of lemon balm due to increasing Cd concentrations also affected EO accumulation. However, this destructive effect was most evident on EO accumulation amongst all investigated parameters. Furthermore, amount of EO decreased by 97%, at the highest concentration. In conclusion, Cd might have damaged both the EO producing mechanism and the structures that produce EO by inhibiting plant growth. Therefore it is important to reveal the responses of all parameters which affect EO production of medicinal plants under various stress conditions.

“…In addition to light intensity, its quality is important for the biochemical activity of plant cells (Pawłowska et al, 2018). The content and composition of essential oils in the leaves of Lippia alba are affected by the genotype and quality of light used during micropropagation (Batista et al, 2016). In Petunia × hybrida 'Mitchell Diploid', red light and far-red stimulated the production of the volatile 2-phenylethanol compound (Colquhoun et al, 2013).…”

In vitro tissue culture technique, especially micropropagation, is attracting increasing attention in the production of ornamental plants. This technique will probably dominate the horticultural market in the near future. Light is one of the several factors affecting the success of in vitro plant tissue cultures. It directly affects the widely understood morphogenetic response of the explant, i.e., the ability of the explant to grow or regenerate, produce roots, etc. Lighting conditions provided during the in vitro stage may also greatly affect the plant vigor after transferring to nonsterile conditions. Moreover, the necessity of providing artificial light significantly contributes to the total cost of maintaining tissue cultures (related to energy consumption and the need to cool down the heat generated by lamps). Light quantity (intensity) and quality (spectral composition) are the two main parameters that determine its influence on in vitro cultures. This impact depends on the species and other accompanying factors. The aim of this mini-review is to summarize information on the influence of light on the morphogenetic and biochemical response of explants of some selected ornamental plant species grown under in vitro conditions.

“…Metabolite biosynthesis, in addition to presenting specificity in relation to tissue and organ, is also regulated by environmental conditions, and its levels may be increased, thus increasing the yields of various compounds or classes of metabolites of medicinal interest. Thus, in vitro cultivation is a very useful and successfully exploited tool, either to provide a better understanding of the biological mechanisms involved between the physical environment and plants or to increase the metabolic levels or specificity (Ouzounis et al, 2015;Batista et al, 2016;Souza et al, 2016).…”

“…Although studies have shown the influence of light quality on plant physiology and behavior, the light spectrum-dependent responses for each species should also be analyzed, as these responses vary greatly and may have different patterns (Batista et al, 2016;Souza et al, 2016;Li et al, 2017;Batista et al, 2018). This study analyzed how light spectrum quality affects growth, chlorophyll, and total phenolic content in M. oleifera plants grown in vitro.…”

All plant parts of the Moringa oleifera can contain relevant concentrations of phytochemicals with health benefits. Plants grown in vitro allow pathogen-free plant material production and rapid propagation, and this technique is widely used to obtain secondary metabolites. This study analyzed how light spectrum quality affects growth, chlorophyll, and total phenolic content in M. oleifera plants grown in vitro. M. oleifera seeds were inoculated in MS medium supplemented with 3% sucrose and 0.7% agar and were stored under a controlled temperature, humidity and photoperiod. The light conditions tested were white fluorescent lamps (WFL) and light-emitting diodes (LED: 70% red + 30% blue), both standardized with a photon flux density of 58 μmol m-2s-1. Radiation emitted by WFL and LED did not influence stem germination, height, or diameter. However, WFL provided higher total chlorophyll levels. All plant parts germinated in vitro were analyzed via high-performance liquid chromatography with a diode-array detector (HPLC-DAD), and preliminary analyses revealed preferential synthesis of gallic acid derivatives in the leaves under LED radiation. For the total phenolic content, leaves under the LED and WFL irradiations showed 3.524 ± 0.054 and 3.805 ± 0.304 micrograms, respectively, of gallic acid equivalents per milligram of dry matter (μg GAE mg-1 DM). Light quality did not interfere with phenolic compound accumulation; however, it stimulated the preferential synthesis of gallic acid derivatives in leaves grown under LED radiation, and the evidence indicated that all evaluated organs synthesized nonpolar substances.
