“…This effect was greater under the higher CO 2 concentration. Several studies showed similar results-e.g., a synchronous increase in Pn, C i , and WUE was observed in the Paris polyphylla cultivars under eCO 2 concentrations (800 µmol mol − 1 ), while g s and Tr remained unchanged [30]. Consistently, different Indica rice cultivars showed an increase in Pn under eCO 2 but no signi cant variations in leaf chlorophyll content during short-term eCO 2 treatment [31].…”

Background: Exposing goji berries to elevated CO2 (eCO2) for long periods reduces sugar and secondary metabolite contents. However, sugar accumulation in fruit depends on photosynthesis and photoassimilate partitioning. The objectives of this study were a) to explore photosynthesis, sugar content, and sucrose metabolism-related enzyme activity in goji berry leaves and fruits under ambient and elevated CO2, and b) to identify the genes encoding Lycium barbarum acid invertase (LBAI), L. barbarum sucrose synthase (LBSS), L. barbarum sucrose phosphate synthase (LBSPS), and L. barbarum neutral invertase (LBNI) based on transcriptome profiling and expression analyses in different tissues. Results: The results showed that the expression of the above genes changed significantly in plants grown under eCO2 for 90 and 120 days as photosynthetic rate increased, while leaf and fruit sugar content decreased and the activity of four sucrose metabolism-related enzymes increased in leaves, and acid and neutral invertase increased in fruits. Furthermore, a significant correlation was detected between sugar content and enzyme activity. The expression of LBAI, LBSPS, and LBNI were high in stems, whereas LBSS was predominantly expressed in fruits. Conclusions: eCO2 affects chlorophyll, photosynthesis, sugars, and related enzyme activities in goji berry leaves and fruits after 90 and 120 days of treatment. Our findings provide fundamental data on photosynthesis and sugar accumulation trends in goji berries under eCO2 exposure.

Medicinal plants, a source of different phytochemical compounds, are now subjected to a variety of environmental stresses during their growth and development. Different ecologically limiting factors including temperature, carbon dioxide, lighting, ozone, soil water, soil salinity and soil fertility has significant impact on medicinal plants′ physiological and biochemical responses, as well as the secondary metabolic process. Secondary metabolites (SMs) are useful for assessing the quality of therapeutic ingredients and nowadays, these are used as important natural derived drugs such as immune suppressant, antibiotics, anti‐diabetic, and anti‐cancer. Plants have the ability to synthesize a variety of secondary metabolites to cope with the negative effects of stress. Here, we focus on how individual environmental variables influence the accumulation of plant secondary metabolites. A total of 48 articles were found to be relevant to the review topic during our systematic review. The review showed the influence of different environmental variables on SMs production and accumulation is complex suggesting the relationship are not only species‐specific but also related to increases and decline in SMs by up to 50 %. Therefore, this review improves our understanding of plant SMs ability to adapt to key environmental factors. This can aid in the efficient and long‐term optimization of cultivation techniques under ambient environmental conditions in order to maximize the quality and quantity of SMs in plants.

Goji berry (Lycium barbarum L.) exposure to elevated CO2 (eCO2) for long periods reduces their sugar and secondary metabolite contents. However, sugar accumulation in fruit depends on photosynthesis and photoassimilate partitioning. This study aimed to explore photosynthesis, sugar content, and sucrose metabolism-related enzyme activities in goji berry leaves and fruits under ambient and eCO2 levels, and identify the genes encoding L. barbarum acid invertase (LBAI), L. barbarum sucrose synthase (LBSS), L. barbarum sucrose phosphate synthase (LBSPS), and L. barbarum neutral invertase (LBNI), based on transcriptome profiling. Further, the characterization of four identified genes was analyzed including subcellular localization and expression patterns. In plants grown under eCO2 for 90 or 120 days, the expression of the above-mentioned genes changed significantly as the photosynthetic rate increased. In addition, leaf and fruit sugar contents decreased, and the activities of four sucrose metabolism-related enzymes increased in leaves, while acid and neutral invertase increased in fruits. Protein sequence analysis demonstrated that LBAI and LBNI contain a conservative structure domain belonging to the glycosyl hydrolases (Glyco_hydro) family, and both LBSS and LBSPS belonging to the sucrose synthase (Sucrose_synth) and glycosyltransferase (Glycos_transf) family. Subcellular localization analysis showed that LBAI, LBNI, and LBSS were all located in the nucleus, plasma membrane, and cytoplasm, while LBSPS was located in the plasma membrane. The expressions of LBAI, LBSPS, and LBNI were high in the stems, whereas LBSS was predominantly expressed in the fruits. Our findings provide fundamental data on photosynthesis and sugar accumulation trends in goji berries under eCO2 exposure.
