“…Thus, the decreased abundance of Lhca3 in 400 µM Cu-treated C. sinensis leaves might contribute to the Cu-induced photoinhibition. This could explain why photoinhibition was slightly greater in 400 µM Cu-treated C. sinensis leaves than that in 400 µM Cu-treated C. grandis leaves [5]. Also, the abundance of protease Do-like 1 (DEGP1; S41) was decreased in 200 and 400 µM Cu-treated C. sinensis leaves.…”

“…Excess Cu-treated C. grandis and C. sinensis leaves had lower CO 2 assimilation ( Figure 1) and higher concentrations of nonstructural carbohydrates relative to controls [5]. Accordingly, many Cu-toxicity-responsive proteins related to photosynthesis, carbohydrate and energy were identified in these leaves (Table 2 and Figure 3).…”

“…Cu concentration and availability in soils under continuous Citrus production orchards increase with increasing production period [2]. In Citrus, the common Cu-toxic symptoms include leaf iron (Fe) chlorosis, poor growth, and stunted, and discolored root systems [3,5].…”

“…Cu, which can act as a cofactor for over 100 proteins including plastocyanin, laccase, cytochrome c oxidase, Cu/zinc (Zn) superoxide dismutase (SOD), ethylene receptors, amino oxidase, polyphenol oxidases, ascorbate (ASC) oxidase, diamine oxidases, and phytocyanin, is involved in photosynthesis, respiration, ATP biosynthesis, ethylene reception, reactive oxygen species (ROS) metabolism, cell wall formation, and carbon, lipid, and nitrogen metabolisms [6]. Accordingly, a lot of researchers have examined the toxic effects of Cu on the uptake of nutrients and water [1,5], growth [1,3], photosynthetic pigment production [7], photosynthetic electron transport [5,8], CO 2 assimilation [8], carbohydrate and nitrogen (N) metabolism [7,9], respiration [10], hormonal status [11], cell wall metabolism [12], phenolic metabolism [13], as well as ROS generation and detoxification [8].…”

This present study examined excess copper (Cu) effects on seedling growth, leaf Cu concentration, gas exchange, and protein profiles identified by a two-dimensional electrophoresis (2-DE) based mass spectrometry (MS) approach after Citrus sinensis and Citrus grandis seedlings were treated for six months with 0.5 (control), 200, 300, or 400 μM CuCl2. Forty-one and 37 differentially abundant protein (DAP) spots were identified in Cu-treated C. grandis and C. sinensis leaves, respectively, including some novel DAPs that were not reported in leaves and/or roots. Most of these DAPs were identified only in C. grandis or C. sinensis leaves. More DAPs increased in abundances than DAPs decreased in abundances were observed in Cu-treated C. grandis leaves, but the opposite was true in Cu-treated C. sinensis leaves. Over 50% of DAPs were associated with photosynthesis, carbohydrate, and energy metabolism. Cu-toxicity-induced reduction in leaf CO2 assimilation might be caused by decreased abundances of proteins related to photosynthetic electron transport chain (PETC) and CO2 assimilation. Cu-effects on PETC were more pronounced in C. sinensis leaves than in C. grandis leaves. DAPs related to antioxidation and detoxification, protein folding and assembly (viz., chaperones and folding catalysts), and signal transduction might be involved in Citrus Cu-toxicity and Cu-tolerance.

This study examines the effects of three irrigation regimes with a combination of saline water and treated wastewater on the accumulation of heavy metals in barley grains. A field experiment was designed as a split‐split plot arrangement in a randomized complete block design, in which treatments were different irrigation regimes (50, 70 and 100% full irrigation) and irrigation water types (saline water (SW), treated wastewater (TW), mixed water resources (MWR) and alternative irrigation (AI)). After cultivation and harvesting of the barley crop, the grain yield, 1000‐grain weight and contents of heavy metals in the grains were measured. The grain yield was enhanced by TW alone, MWR and AI to 12.8, 5 and 9.5% under 70%‐deficit irrigation, and 58.3, 21.7 and 8.7% under full irrigation, respectively. Based on the guidelines for safe limits of heavy metals in edible plants and livestock feed, the barley grains were safe for livestock and toxic for humans. The trend of heavy metal contents in the grains was Fe>Zn>Pb>Cu≥Cr>Cd. Irrigation with saline water compared to treated wastewater increased Fe, Cu, Zn, Pb, Cd and Cr contents in the grains to 11.75, 10.97, 5.22, 19.15, 3.45 and 9.21%, respectively. The amounts of toxic elements of Cd and Pb were maximized by using MWR, while the Cr content in the grain was maximized by using AI. There were no significant difference in the metal uptake by the grains among all irrigation regimes in any irrigation water resource. However, compared to the other irrigation regimes, the full irrigation resulted in lower Zn, Cu and Cd contents, while the 50%‐deficit irrigation led to lower Pb and Cr contents in the grains. Therefore, irrigation with TW is recommended based on the grain yield, while AI is suggested due to lower Cu, Pb and Cd contents in the grain, and MWR is recommended due to lower Cr content. Furthermore, full and 50%‐deficit irrigation regimes are recommended to respectively maximize grain yield and minimize the toxic metal contents in the grain.
