Abstract

Here, we explored the genomic loci and genes responsible for differences in Cs accumulation in the seeds of two soybean (Glycine max (L.) Merr.) cultivars, namely ‘Enrei’ (high accumulator) and ‘Onihadaka’ (low accumulator), using quantitative trait loci (QTL)-seq. For analysis, F3 and F5 generations were generated by crossing the two cultivars followed by self-fertilization. In the putative QTL regions of the F3 generation, Glyma.11G099100 annotated as the vacuolar sorting protein/ubiquitin receptor VPS23 was found. VPS23A regulates the salt overly sensitive (SOS) signaling cascade in Arabidopsis, and mutations in SOS2 reduce radiocesium accumulation in rice grains. In the putative QTL regions of the F5 generation, Glyma.06G112200, which is a homolog of the usually multiple acids move in and out transporter (UMAMIT) proteins in Arabidopsis, was found. UMAMIT proteins are the exporters of amino acids, and the addition of cysteine or its derivative methyl cysteine to the growth medium increased Cs accumulation in A. thaliana. Both Glyma.11G099100 and Glyma.06G112200 carried polymorphisms – an amino acid substitution – between ‘Enrei’ and ‘Onihadaka.’ Yeast cells heterologously expressing the Onihadaka-type Glyma.06G112200 showed higher Cs accumulation than those expressing the Enrei-type. Yeast cells expressing the Enrei-type Glyma.06G112200 showed lower Cs accumulation than the vector controls; however, there was no significant difference between yeast cells expressing the Onihadaka-type and the vector controls. These results suggest that variations in the sequences of Glyma.11G099100 and Glyma.06G112200 in ‘Enrei’ and ‘Onihadaka’ are possibly responsible for differences in Cs uptake between these soybean cultivars.

Abstract

A large amount of radiocesium was released from the accident at Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company. The determination of dissolved and particulate radiocesium concentrations in water is important, which can be used as basic information for understanding the long-term radiocesium dynamics in the environment and the transfer of radiocesium to crops. Conventional quantitative methods include the evaporative concentration to the dryness method and the AMP method. These methods need to concentrate about 20–200 L of water due to the low concentration of the dissolved radiocesium. After the accident, several new methods, such as the Prussian blue filter cartridge method and the solid-phase disk method, have been developed and put to practical use. In this study, we carried out an accuracy evaluation test to assess five methods (i.e., the evaporative concentration to dryness method, the AMP method, the Prussian blue filter cartridge method, the solid-phase disk method, and the ion-change resin method) using 3 types of water samples containing 0.01-1.0 Bq L−1 of dissolved radiocesium. Our results showed that the z-scores of over 80 % of the measured data were within ±2 and their CVs in the range of 8-13 %, indicating good reproducibility of these methods.

36. Effects of Plant Species on CH4 and N2O Fluxes from a Volcanic Grassland Soil in Nasu, Japan

Abstract

To investigate the effects of plant species in grassland on methane (CH4) and nitrous oxide (N2O) fluxes from soil, fluxes from an orchardgrass (Dactylis glomerata L.) grassland, white clover (Trifolium repens L.) grassland and orchardgrass/white clover mixed grassland were measured weekly from April 2001 to March 2002 using a vented closed chamber method. Related environmental parameters (soil inorganic N content, soil pH (H2O) value, soil moisture content, soil temperature, grass yield, and the number of soil microorganisms) were also regularly monitored. On an annual basis, CH4 consumption in the soil of the orchardgrass grassland, white clover grassland and orchardgrass/white clover mixed grassland was 1.8, 2.4, and 1.8 kg C ha-1 year-1, respectively. The soil bulk density of the white clover grassland was lower than that of the other grasslands. Fluxes of CH4 were positively correlated with the soil moisture content. White clover increased the CH4 consumption by improving soil aeration. Nitrogen supply to the soil by white clover did not decrease the CH4 consumption in the soil of our grasslands. On the other hand, annual N2O emissions from the orchardgrass grassland, white clover grassland, and orchardgrass/white clover mixed grassland were 0.39, 1.59, and 0.67 kg N ha-1 year-1, respectively. Fluxes of N2O were correlated with the NO3- content in soil and soil temperature. White clover increased the N2O emissions by increasing the inorganic N content derived from degrading white clover in soil in summer.
