The kelp grouper (Epinephelus bruneus), belonging to one of the largest genera among the subfamily Epinephelinae, is a commercially important fish in Japan. There are limited data about the genomics of this species. To provide tools for addressing both population genetics studies and gene mapping, dito pentanucleotide simple sequence repeat (SSR) markers were developed using 454 pyrosequencing. Among the 1466 SSR markers developed, 1244 primer sets produced strong PCR products, of which 905 (72.7%) were polymorphic in kelp grouper. Cross-species utility of the 905 polymorphic SSR markers was tested in four additional Epinephelinae species of Hyporthodus septemfasciatus, Plectropomus leopardus, Epinephelus lanceolatus and Epinephelus coioides. Results revealed that, respectively, 401 (44.3%), 136 (15.0%), 434 (49.0%) and 538 (59.4%) SSRs showed specific polymorphic products. Of these, 40 SSR markers (33 di-, 1 tri- and 6 tetra-nucleotides) showed polymorphism in all species tested. Additionally, three AGAT SSR motifs which accounted for 42.9% of the nondi-nucleotide markers were found in the 40 SSR markers. This indicates that the AGAT SSR motif has a high potential as a highly versatile SSR marker in grouper Epinephelinae. The SSR markers developed in this study can be employed to obtain reliable genetic variability estimates for groupers (Epinephelinae).

＜正＞Recent advanced techniques in molecular biology have facilitated the dissection of many genetic traits in animals. One of the most important tools of these techniques is genetic linkage maps based on DNA markers such as microsatellite markers. The genetic markers mapped on a linkage map can be used to analyze the quantitative trait loci （QTL） responsible for economically important traits such as disease resistance, growth, and fecundity. In addition, genetic linkage maps also facilitate the positional cloning of functional genes contributing to the quantitative traits. Mapping and identifying the genetic markers linked to economically important traits is critical for marker-assisted breeding. Marker-assisted breeding such as marker-assisted selection （MAS） and marker-assisted gene introgression （MAI） are highly expected to improve the selective breeding programs of aquaculture species. In this paper, we introduce a comprehensive strategy for selective breeding by integrating molecular markers, genetic linkage maps, and QTL data that have been reported in aquaculture species.

The development of vehicle integrated photovoltaics-powered electric vehicles (VIPV-EV) significantly reduces CO2 emissions from the transport sector to realize a decarbonized society. Although long-distance driving of VIPV-EV without electricity charging is expected in sunny regions, driving distance of VIPV-EV is affected by climate conditions such as solar irradiation and temperature rise of PV modules. In this paper, detailed analytical results for effects of climate conditions such as solar irradiation and temperature rise of PV modules upon driving distance of the VIPV-EV were presented by using test data for Toyota Prius and Nissan Van demonstration cars installed with high-efficiency InGaP/GaAs/InGaAs 3-junction solar cell modules with a module efficiency of more than 30%. The temperature rise of some PV modules studied in this study was shown to be expressed by some coefficients related to solar irradiation, wind speed and radiative cooling. The potential of VIPV-EV to be deployed in 10 major cities was also analyzed. Although sunshine cities such as Phoenix show the high reduction ratio of driving range with 17% due to temperature rise of VIPV modules, populous cities such as Tokyo show low reduction ratio of 9%. It was also shown in this paper that the difference between the driving distance of VIPV-EV driving in the morning and the afternoon is due to PV modules’ radiative cooling. In addition, the importance of heat dissipation of PV modules and the development of high-efficiency PV modules with better temperature coefficients was suggested in order to expand driving range of VIPV-EV. The effects of air-conditioner usage and partial shading in addition to the effects of temperature rise of VIPV modules were suggested as the other power losses of VIPV-EV.

A discrete dislocation plasticity analysis of dispersion strengthening in oxide dispersion strengthened(ODS) steels was described. Parametric dislocation dynamics(PDD) simulation of the interaction between an edge dislocation and randomly distributed spherical dispersoids(Y2O3) in bcc iron was performed for measuring the influence of the dispersoid distribution on the critical resolved shear stress(CRSS). The dispersoid distribution was made using a method mimicking the Ostwald growth mechanism. Then, an edge dislocation was introduced, and was moved under a constant shear stress condition. The CRSS was extracted from the result of dislocation velocity under constant shear stress using the mobility(linear) relationship between the shear stress and the dislocation velocity. The results suggest that the dispersoid distribution gives a significant influence to the CRSS, and the influence of dislocation dipole, which forms just before finishing up the Orowan looping mechanism, is substantial in determining the CRSS, especially for the interaction with small dispersoids. Therefore, the well-known Orowan equation for determining the CRSS cannot give an accurate estimation, because the influence of the dislocation dipole in the process of the Orowan looping mechanism is not accounted for in the equation.
