“…Non-essential elements (mainly Res) activate plant response genes, alter plasmatic membrane potential (Kenderesová et al, 2012), and induce ROS and Casignaling (Rodrigo-Moreno et al, 2013) in response to ion effects. The production of antioxidant defenses triggered by the presence of certain non-essential elements depends on the type and concentration of the element but also on the plant species (Rodríguez-Serrano et al, 2009).…”

Plants are essential sources of bioactive substances that promote health. For economic reasons, farmers usually focus on obtaining higher yields rather than crop nutraceutical quality. The application of non-essential elements (NEEs) is a technique used to increase secondary metabolites (SMs) in plants. This technique includes variations of the essential elements ratios in a nutrient solution or the inclusion of elicitors, such as salicylic acid or methyl jasmonate. Elicitor use is controversial because plants grow differently in inert substrates, in vitro and soil. Soil contains essential elements (EEs) and NEEs that can enhance SM synthesis and increase nutraceutical plant quality. However, any technique that modifies plant metabolism can decrease yields. Thus, developing techniques to increase both agricultural product yield and quality is necessary. This review aims to demonstrate the necessity for a new recipe or "cocktail" of plant nutrients based on EEs and NEEs, and elicitors apply to achieve both a high yield and crops nutraceutical quality.

“…The effects of divalent metal cations such as Cd 2+ and Zn 2+ on E M differ mainly according to the available heavy metal concentration, to its affinity status and mode of action [97,98]. A. halleri had lower depolarization of the plasma membrane compared to A. thaliana when exposed to high Zn concentrations, suggesting a different pattern in E M response in hyperaccumulator species [99].…”

“…The root epidermal cells being in direct contact with the environment are more sensitive comparing to the internal root tissues as shown in our previous research on grapevine root cells exposed to cadmium (Fiala et al 2015). The E M was measured using standard microelectrode technique as described in detail by Kenderešová et al (2012). After rinsing with 0.5 mmol L -1 CaSO 4 , the roots were mounted in a 5-mL volume Plexiglas chamber and constantly perfused (5 mL min -1 ) with bathing solution containing 0.1 mmol L -1 KCl and 0.1 mmol L -1 CaSO 4 .…”

-The present study investigated the impact of nickel (Ni 2+ ) on trans-membrane electrical potential (E M ) and permeability properties of plasma membrane (PM) in epidermal cells of adventitious grapevine roots. The relationship between disturbances of membrane functionality and the production of superoxide anion, hydrogen peroxide and cell viability after the exposure of roots to Ni 2+ was also studied. Treatments with 0.1-5 mmol L -1 NiCl 2 induced a concentration-dependent transient PM depolarization, which was recovered to the initial resting potential within 50-70 min in the presence of Ni 2+ . Longer (up to 24 h) exposure of roots to 1 mmol L -1 of Ni 2+ hyperpolarized the E M by approximately 17 mV. Application of the highest 5 mmol L -1 concentration of Ni 2+ during longer treatments (up to 48 h) resulted in the increase of membrane permeability; however the E M , cell viability, and superoxide content remained unaffected. The increase in the formation of hydrogen peroxide was time-and concentration-dependent and maximum production was recorded after 180 min of Ni 2+ treatment. We can conclude that oxidative stress resulting from an imbalance in the generation and/ or removal of hydrogen peroxide in the root tissues of grapevine was the major cause of Ni 2+ toxicity.
