“…The highest carbohydrate content of 85.49 ± 0.42 mg g −1 FW and the least of 58.68 ± 0.5 mg g −1 FW were reported in untreated control plants and plants treated with 2000 ppm Pb, respectively [Table 2]. In response to heavy metal stress, the carbohydrate content has decreased in some plants such as Cajanus cajan [38]; however, it has also been found to increase in some plants such as Glycine max at lower heavy metal concentrations [39]. The loss of carbohydrates in the metal-treated plant can be attributed to the defective photosynthetic machinery caused by metal accumulation.…”

Mucuna pruriens (L.) DC. is a medicinal plant with a wide range of pharmacological properties that have been used in various medicinal preparations for centuries. M. pruriens is a rich source of levodopa (L-DOPA), mainly used to treat Parkinson's disease. The present study investigates the impact of heavy metals such as cadmium (Cd), mercury (Hg), and lead (Pb) on the growth parameters and biochemical characteristics, including the L-DOPA content of M. pruriens. The seeds of M. pruriens were treated with different concentrations of Cd (0-250 ppm), Hg (0-250 ppm), and Pb (0-2000 ppm) for 21 days. On exposure to heavy metals, the germination %, the vegetative growth, and the biochemical characteristics such as the protein, carbohydrate, chlorophyll, total phenol, flavonoid, and proline content varied significantly in the heavy metal-treated plants when compared to control. It was also observed that the L-DOPA content increased with increased metal concentration and then decreased further with higher concentration of metals. The metal accumulation increased with the increase in the metal concentration. The seeds treated with 1000 ppm of Pb showed the highest L-DOPA content compared with control and other treatments.

“…Remarkable enhancement of sucrose, glucose, and fructose levels was observed at high concentrations of salt, because they participate in carbon storage, osmoprotection, osmotic homeostasis, and neutralization of free radicals [54]. The high concentration of copper and nickel inhibits the process of photosynthesis, which leads to a lower sugar content in Glycine max [55]. Heavy metals (Fe, Cu) cause oxidative stress due to reactive oxygen formation and inhibition of photosynthesis and plant metabolism [56].…”

Increasing Sugar Content in Source for Biofuel Production Using Agrochemical and Genetic Approaches at the Stages of BioMass Preharvesting and Harvesting

In order to optimize biofuel (including bioethanol) production processes, various problems need to be solved, such as increasing the sugar content of raw materials/biomass to gain a higher yield of the product. This task can be solved in several ways, with their own advantages and disadvantages, and an integrated approach, such as using a combination of ripening agents and phytohormones or application of a superabsorbent polymer with at least one sugar-enhancing agent, can be applied as well. Here, we reviewed several methods, including pre- and postharvest factors (light, temperature, partial replacement of potassium with magnesium, etc.), genetic modifications (traditional breeding, phytohormones, etc.), chemical ripening methods (Ethephon, Moddus, etc.), and some alternative methods (DMSO treatment, ionic liquids, etc.). The aim of this review was to provide a comprehensive, up-to-date summary of methods of increasing the carbohydrate level in plants/biomass for bioethanol production.

“…Cu has a crucial function in carbon absorption and plant ATP generation [10]. At optimal concentrations, Cu plays an important role in oxidative stress responses, hormone signaling pathways, iron mobilization, and molybdenum cofactor synthesis [11,12]. Proteins called Cu chaperones contain a copper-binding domain, aid in chelating Cu, thereby supporting the intracellular homeostasis of Cu.…”

Zinc and copper pollution in agricultural lands due to anthropogenic activities has become a major environmental problem. While these metals are essential for plant growth, their excessive presence can lead to plant toxicity. This experiment aimed to investigate the effects of different concentrations of zinc and copper (0, 100, 200, and 300 ppm) in soil on the morphological and biochemical properties of I. aquatica, commonly known as water spinach. The morphological properties, including plant height, number of leaves, and stem diameter, were assessed, along with soil pH and electrical conductivity (EC). Biochemical properties, specifically the Total Phenolic Content (TPC) and Total Flavonoid Content (TFC) in plant tissues, were measured using colorimetric assays. The results revealed significant morphological changes in plant height, stem diameter, and number of leaves at 200 ppm zinc treatment compared to the control. Additionally, the number of leaves significantly increased at the 100 ppm copper treatment, while the stem diameter decreased significantly at 300 ppm. Both zinc and copper treatments slightly reduced soil pH and increased soil EC. At the 300 ppm treatment, substantial changes in phenolic and flavonoid contents were observed in the stems and leaves of I. aquatica. Copper treatment at 200 ppm increased the TPC of leaves, while 100 ppm copper treatment increased the TFC of stems. Furthermore, the 300 ppm zinc treatment significantly increased the TPC and TFC in stems and leaves. These findings indicate that zinc and copper concentrations have notable effects on the morphological and biochemical properties of I. aquatica. Therefore, it is crucial to maintain an appropriate balance of these metal elements to cultivate plants that are morphologically and physiologically resilient.
