“…37 found that Ca starvation caused the highest and most significant changes among seven tested variants of nutrient deprivation (14-day-long deficiencies of Ca, S, Mg, K, N, P and Fe) in the ΔV t curve and most of OJIP test parameters for maize, whereas for tomato, the changes that were observed were not so extreme. A decrease in the chlorophyll content (in coffee tree, tomato and rice) and the maximum quantum efficiency of PSII (φP 0 ) (in coffee tree and tomato) under Ca starvation stress have also been documented by other authors 39–41 . We found that seven days of Ca deprivation primarily affected the electron transport to PSI (I-P phase) (Fig.…”

The aim of the research was to compare the impact of short-term deprivation of selected macronutrients (Ca, K, Mg and P) on the photosynthetic characteristics, transpiration and pigment content in maize. The strongest inhibition of photosynthesis was caused by a deprivation of Mg, which was visible as a decrease in the photosynthetic and transpiration rates, stomatal conductance, photosystem II (PSII) performance, chlorophyll and flavonol content with a simultaneously increased content of anthocyanins. In the K-deprived plants, a decrease in the photosynthetic rate was observed. However, the transpiration rate and stomatal conductance did not differ significantly compared with the control. In the K-deprived plants, a decrease in chlorophyll and an increase in the anthocyanin content were also observed. We showed that Ca starvation resulted in a decrease in the photosynthetic and transpiration rates, stomatal conductance and PSII performance, while the pigment content was not significantly different compared with the control. In the case of P-deprived plants, we observed a decrease in the photosynthetic and transpiration rates. Interestingly, the inhibition of stomatal conductance was the strongest in the P-deprived plants compared with all of the investigated elements. However, the performance of PSII was not significantly affected by P starvation compared with the control. Our results present for the first time a comprehensive analysis of the effect of short-term macronutrient deprivation on photosynthesis and transpiration in maize plants.

“…This result might be explained by the fact that Ca, which is an important primary signal transduction element (Cho et al . ), can induce Cd stress response genes in rice plants and cause plants to better tolerate Cd stress conditions. In addition, low concentrations of Ca in the plant cells can also cause plant membrane injury and reduce antioxidant capacity (Schmitz‐Eiberger et al .…”

Calcium (Ca) signalling has an essential role in regulating plant responses to various abiotic stresses.• This study applied Ca in various forms (Ca acetate and CaCl 2 ) and concentrations to reduce cadmium (Cd) concentration in rice and propose a possible mechanism through which Ca acts to control the Cd concentration in rice.• The results showed that supplementation of Cd-contaminated soil with Ca acetate reduced the Cd concentration in rice after exposure for 7 days in both hydroponic and soil conditions. The possible involvement of the auto-inhibited Ca 2+ -ATPase gene (ACA) might act to control the primary signal of the Cd stress response. The messages from ACA3 and ACA13 tended to up-regulate the low-affinity cation transporter (OsLCT1) and down-regulate Cd uptake and the Cd translocation transporter, including the genes, natural resistance-associated macrophage protein 5 (Nramp5) and Zn/ Cd-transporting ATPase 2 (HMA2), which resulted in a reduction in the Cd concentration in rice. After cultivation for 120 days, the application of Ca acetate into Cdcontaminated soil inhibited Cd uptake of rice.• Increasing the Ca acetate concentration in the soil lowered the Cd concentration in rice shoots and grains. Moreover, Ca acetate maintained rice productivity and quality whereas both aspects decreased under Cd stress.

“…Previous reports have also shown the importance of the nutrient-status on the capacity of Rhizobium -nodulated (+Rh) legumes to tolerate HI (Izaguirre-Mayoral and Sinclair, 2009). Among all the nutrients required for plant growth, Ca is considered a signal molecule (Brownlee and Hetherington, 2011; Cho et al , 2012; Huang et al , 2012; Sarwat et al , 2013) that triggers defence mechanisms for tolerance to HI (Chen et al , 2007; Luo et al , 2009; Snider et al , 2011; Zhao and Tan, 2005). On the other hand, deficiency of P in leaf tissues depresses net photosynthesis which results in an accumulation of photon energy that aggravates the deleterious effects of HI on plants (Nilsson et al , 2012; Weng et al , 2008).…”

Interactions between two contrasting photosynthetic photon flux densities (PPFD) and increasing Ca and P concentrations were analysed in N-fertilised (+N) and Rhizobium-inoculated (+Rh) Phaseolus vulgaris plants grown for 30 days in glasshouses. Plants were grown in sand-filled Leonard jars with 0.9 L N-free for +Rh plants or plus 6 mM KNO 3 for +N plants nutrient solution, pH 6.2 in the lower compartment, and were subjected to midday PPFD ࣙ 1650 ࣘ 1800 mmol m −2 s −1 /37±2°C air temperature (HI/HT) or PPDF ࣙ 900 ࣘ 1200 μmol m −2 s −1 /26±2°C air temperature (MI/MT). The nutrient solutions were supplied with 1, 2, 3 or 4 mM P in combination with 1 or 4 mM Ca. Results revealed a 100% mortality of the HI/HT+Rh plants at the juvenile stage of growth. Whereas, all HI/HT+N plants reached the preflowering stage but showed smaller shoot masses, lower chlorophyll concentrations, unusually high chlorophyll a/b ratios and higher shoot nitrate concentrations when compared to values in +N plants grown at MI/MT. Increasing concentrations of P and Ca, or the daily spray of leaves with 2 mM propyl gallate (Pg), did not counteract the negative effects of HI/HT on +Rh and +N plants. Maximum growth, nodulation, chlorophyll concentration and catabolism of ureides in leaves were exclusively observed in +Rh plants grown under MI/MT conditions and supplied with 2 mM P and 1 mM Ca. In contrast, the greater growth of +N plants, associated with higher chlorophyll and nitrate concentrations, took place at MI/MT conditions combined with 1 mM P and 4 mM Ca. Pg further enhanced the growth of MI/MT+Rh and MI/MT+N plants grown at P < 2 mM, at 1 or 4 mM Ca, respectively. At MI/MT, there was a positive relationship between leaf carotenoid concentration and growth of +Rh and +N plants.
