“…These findings are in agreement with previous studies that reported similar changes in 134 Cs concentration in plants due to soil liming (Jackson and Nisbet, 1990;Lembrechts, 1993;Nisbet et al, 1993;Putyatin and Seraya, 2007;Choi et al, 2008;Monna et al, 2009). However, the variability of 134 Cs plant concentration is much lower than that observed in a previous experiment (z40 for radish roots and z200 for cucumber fruits) when six plants were grown on eight different mineral soils (Skarlou et al, 1996).…”

“…Letter in common indicates lack of significant difference (Tukey's HSD test, a < 0.05); comparisons are valid within each plant part (edible or vegetative). (Lembrechts, 1993;Valcke et al, 1997;Putyatin and Seraya, 2007;Choi et al, 2008). Accordingly, the findings of the present study indicate a very strong effect of lime application in the acid sandy soil on 134 Cs plant uptake that is apparently also influenced by the plant species.…”

“…Under elevated Ca 2+ concentrations, interaction of this ion with CaM can lead to displacement of cyclic nucleotides and channel closure (Kaplan et al 2007). When Ca 2+ content is available at low levels in the external environment, plant development is affected as a result of Ca 2+ deficiency (Choi et al 2008).…”

Cyclic nucleotide-gated channels (CNGCs) are a class of nonselective cationic channels that are widely found in animals and plants. Plant CNGCs participate in numerous biological functions that vary from development to stress tolerance. Most CNGC genes have been identified in plant genomes, but no such comprehensive study has yet been conducted on Chinese cabbage. In this study, thirty BrCNGC genes were identified, divided into five groups, and used for evolutionary analysis. We assigned names of all individual CNGC members on the basis of phylogenetic relationship with A. thaliana CNGCs. All BrCNGC genes were randomly distributed on chromosomes, and the A08 chromosome did not carry any CNGC gene. The CNGC genes of Chinese cabbage and A. thaliana from the same group displayed similar conserved motifs and gene structures. Especially the closer the homology, the higher the similarity. Quantitative expression analysis showed that most of the CNGC genes were expressed under four stresses, indicating that they play a key role in the stress response of Chinese cabbage. Expression patterns of 12 BrCNGC in the roots, stems, leaves, flowers, and siliques showed that BrCNGC8 and BrCNGC16 were specifically expressed only in flowers but not in other parts. This study lays a theoretical foundation for future research on the function of the CNGC gene family in Chinese cabbage.

“…Although model studies using artificially contaminated media have been performed on vegetables and oil crops (Bengtsson et al, 2013;Choi et al, 2008;Nisbet and Shaw, 1994;Yasutaka et al, 2014), studies on the effect of radiocesium exposure on vegetables and oil crops cultivated in fields near the nuclear power plant after the accident are difficult to perform, but are important. Radiocesium activity concentrations (RCs conc.…”

“…The present study focused on Brassica napus because its flowers have ornamental value and this plant is a valuable vegetable and seed oil crop. In addition, B. napus is suitable for extensive cultivation and is a member of the Brassicaceae family, which is known to include crop species with comparatively higher radiocesium transfer coefficients; thus, this species shows potential for phytoremediation (Choi et al, 2008;Fuhrmann et al, 2002;Lasat et al, 1997). B. napus was in fact previously studied for its potential use in environmental recovery from the tsunami disaster caused by the Great East Japan Earthquake (Yong et al, 2015).…”

Brassica napus was cultivated in three test fields exposed to different radionuclide contamination levels 1.5 years after the Fukushima Daiichi nuclear power plant accident to investigate the correlation between soil contamination and radiocesium activity concentration (RCs conc.) in plants. The correlations between total and exchangeable RCs conc. were strong in the plow layer (L1) and the layer 5 cm below L1 (L2). Watersoluble radiocesium was not detected in either layer, and little radiocesium penetration was observed below L2. Correlation coefficients between RCs conc. in each plant organ and soil layers were calculated. Correlations between RCs conc. in each vegetative organ and total and exchangeable RCs conc. in L1 and correlations between vegetative organs were mostly strong during vegetative growth and flowering periods. Correlations between RCs conc. in flowers with that in L1, L2, and other vegetative organs were not significant. RCs conc. in L1 may more directly affect concentrations in roots and shoots. RCs conc. in oil extracted from seeds was measured, and the results suggested that radiocesium was not detectable in the oil fraction. Our data regarding radiocesium in soil and plants and their correlations obtained by extensive cultivation in contaminated soils could be useful to gain a better scientific understanding of radiocesium transport and accumulation and to provide useful information for the future utilization of areas with low contamination levels.
