ZIP （ZRT/IRT-like Protein） and CDF （Cation Diffusion Facilitator） are two large metal transporter families mainly transporting zinc into and out of the cytosol. Several ZIP and CDF transporters have been characterized in mammals and various model organisms, such as yeast, nematode, fruit fly, and zebrafish, and many candidate genes have been identified by genome projects. Unexpected functions of ZIP and CDF transporters have been recently reported in some model organisms, leading to major advances in our understanding of the functions of mammalian counterparts. Here, we review the recent information on the sequence similarity and functional relationship among eukaryotic ZIP and CDF transporters obtained from the representative model organisms.

Rice blast, which is caused by the fungus Magnaporthe oryzae, is a widespread and destructive plant disease that greatly reduces yield and grain quality worldwide. The use of host resistance is the most effective and economic way to control plant diseases. Many studies on blast resistance genes have focused on the nucleotide-binding site leucine-rich repeat （NB-LRR） resistance （called typical R） genes that mediate effector-triggered immunity. However, incorporating these R genes into rice varieties has not achieved durable blast resistance, because R-gene-mediated resistance is race-specific and often breaks down owing to the appearance of fungal variants that escape host recognition. Thus, the deployment of genes conferring non-race-specific du- rable resistance is highly desired by breeders. In plants, several genes conferring non-race-specific durable resistance genes have been isolated, but only a few of the molecular mechanisms responsible for resistance have been determined.

Transparent electrodes made of silver nanowires （AgNWs） exhibit higher flexibility when compared to those made of tin doped indium oxide （ITO） and are expected to be applied in plastic electronics. However, these transparent electrodes composed of AgNWs show high haze because the wires cause strong light scattering in the visible range. Reduction of the wire diameter has been proposed as a way to weaken light scattering, although there have seldom been any studies focusing on the haze because of the difficulty involved in controlling the wire diameter. In this report, we show that the haze can be easily reduced by increasing the length of AgNWs with a large diameter. Ultra-long （u-long） AgNWs with lengths in the range of 20-100 μm and a maximum length of 230 μm have been successfully synthesized by adjusting the reaction temperature and the stirring speed of a one-step polyol process. Compared to typical AgNWs （with diameter and length of 70 nm and 10 μm, respectively） and ITO, a transparent electrode consisting of u-long AgNWs 91 nm in diameter demonstrated a low haze of 3.4%-1.6% and a low sheet resistance of 24-109 Ω/sq. at a transmittance of 94%-97%. Even when fabricated at room temperature without any post-treatment, the electrodes composed of u-long AgNWs achieved a sheet resistance of 19 Ω/sq, at a transmittance of 80%, which is six orders of magnitude lower than that of typical AgNWs.

Homogeneous columnar Cu film with fully embedded nanotwins was successfully fabricated on Ti/Cu seed layer on silicon wafer. The nanotwins with thickness of tens of nanometers are generally parallel to the silicon surface, showing a strong （111 ） preferred orientation. The acid concentration was found to be important in influencing the formation of nanoscale twins. By adjusting the acid concentration, the nanotwins can be induced from the top columnar grain to middle columnar grain and reach the bottom equiaxed grain, and a microstructural transformation model was given. A theory focusing on the cathode overpotential was proposed to reveal the effect of acid concentration on the growth mechanism of nanoscale twins. An appropriate adsorption proportion of hydrogen on cathode （acid concentration 17 ml L^-1） could increase the overpotential which supplies adequate nucleation energy for nanoscale twins formation.

A three-year sampling campaign was conducted at a roadside air pollution monitoring station in the urban area of Kanazawa, Japan. Due to a new emission regulation, PAHs levels decreased over the sampling campaign, exhibiting values of 706 ± 413 pg/m^(3) in 2017, 559 ±384 pg/m^(3) in 2018, and 473 ± 234 pg/m^(3) in 2019. In each year, similar seasonal variations in PAHs levels were observed, with higher levels observed in winter and lower levels in summer. Among the PAHs isomer ratios, we observed that the ratio of benzo[b]fluoranthene(BbF) and benzo[k]fluoranthene(BkF), [Bb F]/([BbF] + [BkF]), and the ratio of indeno[1,2,3-cd]pyrene(IDP) and benzo[ghi]perylene(BgPe), [IDP]/([BgPe] + [IDP]), showed stability over the sampling campaign and were less affected by the new emission regulation, seasonal variations, and regional characteristics. When using the combined ratio ranges of 0.66-0.80([Bb F]/[BbF] + [BkF]) and 0.26-0.49([IDP]/[Bg Pe] + [IDP]), traffic emissions were clearly distinguished from other PAHs emission sources. Principal component analysis(PCA) and positive matrix factorization(PMF) were also performed to further analyse the characteristics of traffic-related PAHs. Overall, this study affirmed the effectiveness of the new emission regulation in the reduction of PAHs emissions and provided a combined range for identifying PAHs traffic emission sources.

该文以经过120 d、温度90℃条件下窑干干燥处理的56根日本柳杉人工林结构材(110 mm×55 mm×2 500 mm)作为测试试件,介绍了一种利用激光测距系统测量顺纹抗拉弹性模量的方法.首先将试件含水率调至15%,在抗拉试验开始前采用纵向基频振动方法(FFT)得到试件的动态弹性模量(Efr),再利用由激光测距仪、数据采集器和计算机处理系统组成的激光测距系统,测定了顺纹抗拉弹性模量(Et),最后破坏试件完成顺纹抗拉强度(σt)的测定.对Efr、Et和tσ相互关系的比较分析表明,Et的平均值比FFT方法得到的Efr的平均值小7.8%(0.63GPa);Et与Efr具有很好的相关性,相关系数R为0.971,在0.001水平上呈显著相关;Et和σt的相关系数R为0.727,也在0.001水平上呈显著相关.足尺试件的顺纹抗拉测试结果表明,激光测距方法可以准确地测量结构材在顺纹受拉时发生的拉伸变形,从而得到可靠的抗拉弹性模量试验结果.
