“…The current study, using selenite (SeO 3 2 ) as the Se fertilizer, is consistent with the results of Zhang et al (2017) . In contrast, Altansuvd et al (2014) pointed out that the Se content of potato, wheat, and barley grown in high available P soil was higher than those in low available P soil, and total soil Se was significantly correlated with P availability in soil. During previous studies ( Mora et al, 2008 ; Sanghun et al, 2011 ), it was observed that moderate P supply combined with Se fertilization could increase grain yield while P application had a negative effect on increasing grain Se concentration, thus avoiding excessive P application in agricultural practice is critical for the balance of obtaining higher grain yield and appropriate grain Se concentration in plants.…”

“…Earlier reports showed that Se concentration and accumulation were dependent on the status of P nutrition in plants ( Cater et al, 1972 ; Lévesque, 1974 ; Singh and Malhotra, 1976 ; Singh and Singh, 1978 ; Altansuvd et al, 2014 ; Zhang et al, 2017 ). As expected, the current study results clearly indicated that increasing P supply levels greatly decreased Se concentration and accumulation in roots, stems, and leaves of winter wheat ( Table 1 ).…”

Selenium (Se) is a necessary trace element for humans and animals, and Se fertilization is an efficient way to increase Se concentration in the edible parts of crops, thus enhance the beneficiary effects of Se in human and animal health. Due to the similarity of physical and chemical properties between phosphate () and selenite (), phosphorus (P) supply often significantly impacts the absorption of Se in plants, but little is known about how P supply influences the subcellular distribution and chemical forms of Se. In this study, the effects of P supply on subcellular distribution and chemical forms of Se in winter wheat were investigated in a hydroponic trial with medium Se level (0.1 mg Se L-1). P was applied with three concentrations (0.31, 3.1, and 31 mg P L-1) in the experiment. The results showed that increasing P supply significantly decreased the concentration and accumulation of Se in the roots, stems, and leaves of winter wheat. An increase in P supply significantly inhibited Se accumulation in the root cell wall, but enhanced Se distribution in the organelles and soluble fraction of root cells. These findings suggest that increased P supply inhibited the root-to-shoot transport of Se. An increase in P supply enhanced Se accumulation in the cell wall of plant stems (both apical and axillary stem) and cell organelles of plants leaves, but inhibited Se distribution in the soluble fraction of stems and leaves. This suggests that P supply enhances Se transportation across the cell membrane in shoots of winter wheat. In addition, increased P supply also altered the chemical forms of Se in tissues of winter wheat. These findings will help in understanding of the regulation grain Se accumulation and provide a practical way to enhance Se intake for humans inform Se-enriched grains.

“…Many studies have reported that Se uptake of crop could be increased by Se application in wheat (Germ et al 2013), maize (Chilimba et al 2012), rice (Li et al 2010) and other crops (Altansuvd et al 2014). Single effects of foliar spray or application via root of Se on grain Se concentration and yield have been recognized in buckwheat under controlled conditions (Vogrinčič et al 2009).…”

Selenium (Se) is a significant trace element for human and livestock animals because of its physiological functions. Se in plants, especially in the crop plants, is treated as a critical dietary source. The effects of foliar spray together with soil application of Se on Se uptake, distribution in common buckwheat (Fagopyrum esculentum M.) plants were discussed in this study. The results showed that both foliar spray and soil application of Se increased Se uptake in common buckwheat significantly (P < 0.05). The highest Se content was observed in leaves (113.37-690.75 μg/ kg), followed by roots (28.98-283.78 μg/kg), grains (26.49-135.89 μg/kg) and stems (23.19-86.80 μg/kg). Se content in grains had the highest correlation coefficient (0.827 and 0.845) with soil Se application treatments. Grain yield of F1 (5 g Se/ha for foliar spray) was 3.65% and 10.25% higher than that of F0 (0 g Se/ha for foliar spray) in two study years, respectively. Under soil Se application conditions, mean grain yields fluctuated from 2890.5-3058.6 kg/ha, 2966.4-3352.8 kg/ha in 2012/2013, respectively. These results indicated a significant interaction effect of foliar spray Se and soil Se application on Se accumulation in common buckwheat. Appropriate Se application might improve common buckwheat grain yield.

“…Nevertheless, the inverse tendency was achieved in field or pot experiments. For instance, the Se uptake of barley, potato, and wheat grown in high P-availability soil was much greater than those in low P-availability soil (Altansuvd et al, 2014), and P addition to the soil enhanced the Se uptake of alfalfa grown in six soil types (Carter et al, 1972). Therefore, the specific effect of P on Se uptake by plants depends both on the P dosage as well as the environmental conditions.…”

Selenite and phosphate share similar uptake mechanisms, as a phosphate transporter is involved in the selenite uptake process. However, the mechanism by which selenium (Se) transformation in plants is mediated by phosphorus (P) remains unclear. In this hydroponic study, the absorption, translocation, and biotransformation of Se in selenitetreated rice (Oryza sativa L.) seedlings were investigated under varying P nutrient status. The results showed that P-deficient cultivation increased the Se concentration in roots with Se-only treatment by 2.1 times relative to that of the P-normal condition. However, co-treating roots with additional P caused the Se concentration to decline by 20 and 73% compared to Se treatment alone under P-normal and P-deficient cultivation, respectively. A similar pattern was also observed in Se uptake by rice roots. With an Se-transfer factor elevated by 4.4 times, the shoot Se concentration was increased by 44% with additional P supply compared to the concentration under Se-only treatment of P deficiency; however, no significant differences were observed regarding P-normal cultivation. P deficiency increased the Se percentage by 28% within the cell wall, but reduced it by 60% in the soluble fraction of Se-only treated roots relative to that of the P-normal condition. Contrarily, compared with the Se-only treatment under P deficiency, additional P supply enhanced Se storage in the root soluble fraction by 1.3 times. The opposite tendency was observed for rice shoots. Moreover, P deficiency reduced the proportion of SeMet by 22%, but increased MeSeCys by 1.3 times in Se-only treated roots compared to those under the P-normal condition. Interestingly, MeSeCys was not detected when additional P was added to the two cultivation conditions. Unlike in the roots, only SeMet was generally detected in the rice shoots. The results demonstrate that the P nutrient status strongly affects the Se biofortification efficiency in rice seedlings by altering the Se subcellular distribution and speciation.
