“…Plants convert light energy into chemical energy through photosynthesis and store light energy in the body to provide energy for their own growth ( Yi Wen and Shi, 2018 ; Gupta and Nath, 2020 ). But different plants have different sensitivities to light, as do medicinal plants ( Zou et al, 2020 ; Lv et al, 2021 ). According to the different needs of medicinal plants for light, it can be divided into three categories: sunny plants such as Rehmannia and licorice; shade plants such as Panax notoginseng and ginseng; and intermediate plants with moderate light need ( Wu, 2013 ), such as Ophiopogon japonicus and Viola philippica .…”

Light quality consists of a spectrum of different bands, which not only affects plant, development, and primary metabolism but also affects the secondary metabolism of plants. It is an important factor affecting the content of active components of medicinal plants. The A. paniculata seedlings planted in the laboratory, as materials, were tested with red light, far red light, blue light, and ultraviolet light separately. The study assays the content of six main chemical components separately by LC-MS, observes the changes in the content, and analyzes the relationship between the light quality and the active ingredient of A. paniculata. Using the ointment yield and pH value, the fingerprint analysis method of A. paniculata standard decoction was established, and we discussed the selection of index components of A. paniculata standard decoction. It was suggested to select andrographolide as the index component. It will provide a theoretical basis for the large area cultivation of A. paniculata and optimize the quality of medicinal materials to ensure the quality of standard decoction.

“…Alterations in the morphology and function of plant tissues have been reported owing to changes in light quantity, quality, and duration, and these alterations have been shown to be species-specific. For instance, Li et al (2010) [19] suggested that blue light significantly increased the chlorophyll level, leaf thickness, palisade parenchyma length, and stomatal area of Gossypium hirsutum compared with the control, while Zou et al (2020) [20] reported that blue light decreased the growth rate, root length, and photosynthetic efficiency of A. thaliana. Our previous work also found that a proper blue/red light ratio can increase the Cd removal efficiency of Noccaea caerulescens by simultaneously enhancing its metal uptake capacity and oxidation resistance [21].…”

Alterations of Amino Acid Concentrations and Photosynthetic Indices in Light Irradiated Arabidopsis thaliana during Phytoextraction

et al. 2021

Hyperaccumulation of heavy metals is substantial in some hyperaccumulators; however, few studies have been conducted to reveal the effect of light irradiation on the variations of representative amino acids and photosynthetic indices, which can represent the antioxidant capacity of plants during phytoremediation. The physiochemical responses of Arabidopsis thaliana to Cd stress were compared during six light irradiation treatments. The results of the experiment showed that the stress adaptation of A. thaliana was enhanced in all light irradiation treatments, except for monochromatic blue-light irradiation. The concentrations of glutamic acid and glutamine decreased significantly in pure blue light compared with the other treatments. The decrease in the concentrations of these two amino acids might be induced by an intensive biosynthesis of defensive factors, as manifested in the declined photosynthetic indices. Concentrations of aspartic acid and asparagine involved in the ammonification, absorption, and transportation of nitrogen in vascular plants increased in the red and blue combined irradiation treatments compared with the control, corresponding to the improved photosynthetic capacity of the species. The concentration of proline, which can represent environmental stresses including metal toxicity and excessive light energy, generally increased with an increasing ratio of blue light. This study proposes the key roles of amino acids and photosynthetic indices in light-motivated Cd pollution responses in A. thaliana.
