“…In brown rice, the highest increases were found for mannose (108%) and maltose (60%). This observation contrasted with earlier ones on vegetative organs from the same experiment, in which plants grown under elevated [CO 2 ] had 22% (P < 0.01) more starch stored in their leaves at the flowering stage (Goufo et al 2014b). Bran sugars were mostly unaffected by the elevated [CO 2 ], because only arabinose increased (85%, P = 0.01).…”

“…The rice field experiment was conducted in two consecutive years (2011 and 2012) in Salvaterra de Magos (central Portugal; latitude, 39°2.2015′N; longitude, 8°44.257′W; and elevation, 18 m above mean sea level) on a clay loam soil (197 g/kg of sand, 269 g/kg of silt, and 534 g/kg of clay). Six open-top chambers (4.0 m diameter, 2.5 m height, 3.2 m open-top diameter) covered with a polyethylene film (75% light transmittance) were used in the field and constructed as described elsewhere (Pereira et al 2013;Goufo et al 2014b). 1).…”

Cereal Chem. 91(3):293-299Little is known regarding the impact of elevated carbon dioxide concentration ([CO 2 ]) on the chemical composition of rice grains. A field experiment was conducted with open-top chambers with rice (Oryza sativa L. cv. Ariete) grown at two levels of atmospheric CO 2 (375 and 550 μmol/mol), and their effects were monitored on the proximate composition and carbohydrate contents of the grains. Following exposure to elevated [CO 2 ], soluble dietary fiber increased by 136, 82, and 77% in brown rice, white rice, and bran, respectively. Increases of a lower magnitude (8%) were observed for insoluble dietary fiber in the bran and brown rice.* The e-Xtra logo stands for "electronic extra" and indicates that Figure 2 appears in color online.

“…Phenols are products of the secondary metabolism of plants, which acts to combat free radicals (Goufo et al, 2014); they are a mechanism of chemical defense against insects, weeds and plant pathogens. The results of studies show that when soybeans are combined with high proportions of the resistant biotype or are subject to interspecific competition, they activate these defense mechanisms.…”

-Herbicide resistance can cause biochemical, physiological, morphological and phenological changes in weeds, altering their competitive ability against crops. The aim of the study was to assess physiological changes and cellular damage in susceptible and resistant biotypes of ryegrass and soybeans under competition. Three experiments were conducted in a greenhouse using a completely randomized design with four replications performed in a replacement series. The ratios of soybean and to susceptible (experiment 1) and resistant ryegrass (experiment 2) and of susceptible to resistant (experiment 3) ryegrass were 100:0, 75:25, 50:50, 25:75 and 0:100. Forty days after the emergence of the soybean crop and 60 days after the emergence of the ryegrass plants, the leaves of the competing plants were collected. The following variables were assessed: the levels of carotenoids, chlorophylls and total phenolic compounds; amount of hydrogen peroxide; degrees of lipid peroxidation and electrolyte leakage; and activity of enzymes catalase, superoxide dismutase and ascorbate peroxidase. The production of phenols and increased oxidative damage due to interspecies competition with ryegrass was, in general, observed in the soybeans; the ryegrass biotypes, susceptible and resistant to glyphosate, coexisting with soybean have generally higher oxidative damage due to intraspecific competition; since when these biotypes coexist not present modifications of these parameters.Keywords: oxidative stress, antioxidant enzymes, adaptability of herbicide resistant plants. RESUMO -A resistência aos herbicidas pode causar mudanças bioquímicas,fisiológicas, morfológicas ou fenológicas nas plantas daninhas alterando a capacidade competitiva com as culturas.O objetivo do estudo foi verificar alterações na fisiologia e os danos celulares em biótipos de azevém resistente

“…In addition, the concentrations of most phytochemicals in most tissues are likely to be low compared to major nutrients and strongly depend on many factors including genotype, plant part and plant developmental stage [41]. Therfore, a good deal of caution is warranted in comparing such disparate studies to draw valid conclusions.…”

Elevated CO<sub>2</sub> Levels Affect Phytochemicals and Nutritional Quality of Food Crops

Rising atmospheric CO 2 levels pose many challenges to global climate, thus to all forms of life including plants. The impact of elevated CO 2 on plant growth and development and the nutritional quality in relation to major nutrients in many crops has been explored extensively. However, information on the elevated CO 2 effects on the health-promoting phytochemicals in food crops is rather limited. Major nutrients in food crops including protein, phosphorus, potassium, calcium, iron, zinc and other micronutrients in many food crops are known to be suppressed at elevated CO 2 levels. Elevated CO 2 increases carbohydrate accumulation but decreases nitrogen accumulation in plants thus affecting their C-N ratio. A number of studies show that high C-N ratio and nitrogen limiting conditions in plants can result in the accumulation of carbon-based secondary metabolites, many of which are health-promoting phytochemicals and allelochemicals involved in plants' defense against pathogens and herbivory. Although the results from these studies are variable, it can be concluded that while elevated CO 2 is known to suppress the content of major nutrients, it may actually have a favorable impact on the accumulation of carbon-based phytochemicals in food crops.
