“…Indeed, it has been shown that fruit development imposes considerable demands for K, which is implicated in metabolic processes, such as the synthesis of proteins, enzyme activation, membrane transport processes, and the generation of turgor pressure (Chapagain and Wiesman, 2004). Yet, along fruit development, Cu, that plays a key role in growth process (Hänsch and Mendel, 2009), displayed a lower level, as compared to the control, contributed probably to limited fruit growth, as suggested by Flynn et al (1987), who reported reduction on grain yield and quality under copper deficiency. Although mineral composition was affected by Cd treatment in different fruit development phases, red fruits exhibited little variations in their nutritional status, as compared to control, suggesting the strong ability of tomato plant to acquire tolerance to moderate Cd concentration.…”

a b s t r a c t Edited by RA Street Keywords: Cadmium Mineral elements Solanum lycopersicum Seed FruitIn young tomato plants, modifications in mineral composition by short-term cadmium (Cd) treatments have been extensively examined. However, long-term Cd treatments have been fewly investigated, and little information about Cd-stress in fruiting plants is available. In the present work, we examined the changes in mineral nutrients of roots, stems, leaves, flowers, seeds and fruit pericarp of tomato plants submitted to a long-term Cd stress. After a 90-day culture period in hydroponic contaminated environment (0, 20 and 100 μM CdCl 2 ), fruit production was affected by increasing external Cd levels, with the absence of fruit set at 100 μM Cd. Meanwhile, Cd altered the plant mineral contents with an element-and organ-dependent response. At 20 μM, Cd triggered a significant increase in Ca content in roots, mature leaves, flowers and developing fruits. However, at 100 μM Cd, Ca content was reduced in shoots, and enhanced in roots. Cd stress reduced Zn and Cu contents in shoots and increased them in roots. High Cd level led to a significant decrease in K and Mg content in all plant organs. Furthermore, Fe concentration was reduced in roots, stems and leaves but increased in flowers, seeds and red ripe fruits. Our results suggest that tomato plants acclimatize during long-term exposure to 20 μM Cd, while 100 μM Cd results in drastic nutritional perturbations leading to fruit set abortion.

“…Micronutrients also have an impact on nutrition and quality of wheat flour. For example, copper deficiency affected the extensibility of dough (Flynn et al 1987). Zinc (Zn) plays an important role in the formation of protein and nitrogen assimilation process in grains of winter wheat (Li et al 2011); Zn nutrition can affect flour quality by influencing the proportion of monomeric gliadins vs. polymeric glutenins.…”

Wheat flour protein components affect the processing quality of wheat. While it is known that zinc (Zn) fertilization can change flour protein content, there is little knowledge about Zn influence on flour protein composition. A pot experiment was conducted with five Zn fertilization treatments and three wheat genotypes differing in protein concentration and gluten composition. Zn fertilization up to 10 mg Zn/kg soil increased activity of nitrate reductase and glutamine synthetase in flag leaves after flowering, but 40 mg Zn/kg soil caused a genotype-dependent decline in these activities. Similarly, an increase in Zn fertilization was associated with a genotype-dependent increase in grain protein content and concentrations of gliadins, glutenins, albumins and globulin in flour, followed by a decrease of all three protein types at 40 mg Zn/kg soil. These results demonstrate that Zn nutrition can alter flour protein content and composition in wheat that has differential end uses, influencing flour quality.

“…As copper (Cu) is essential for chlorophyll synthesis, protein synthesis, and plant respiration, 121 its application, as a foliar spray at late tillering and/or booting stage (CuSO 4 •5H 2 O, 0.2 kg Cu ha −1 ), leads to an increased grain yield. Moreover, Flynn et al 122 briefly illustrated a significant improvement of the baking quality due to a Cu treatment applied at the booting stage. It was found that both dough rheology and loaf volume was enhanced.…”

The increasing interest in the production of bread wheat ( Triticum aestivum L.) with specific quality traits requires a shift from the current breeding goal, being yield, to improved compositional and, consequently, functional traits. Since wheat is a key food crop, this must be attained while maintaining or even further increasing yield. Furthermore, as compositional requirements for specific applications are not well-defined, both protein and gluten content as well as the enzymatic activity remain most important. Given that these traits are majorly impacted by both genotype and environment, it is very complex to predict and ultimately control them. Different strategies, such as applying optimized agronomic practices, can temper these uncontrollable determinants which are equally important to steer wheat quality. As current research on their contribution to specific traits is highly fragmented, this report provides a comprehensive review of the influence of crop husbandry and environmental conditions on wheat yield and composition.
