In 2019, Indonesia was ranked second with 619,840.03 carbon emissions, after India. Therefore, the Indonesian government issued a zero emission plan in 2022 and encouraged Indonesians to purchase electric vehicles, striving to achieve zero emissions by 2060. Facing the huge potential market for the development of electric vehicles in Indonesia, the Chinese brand Wuling took this opportunity to launch its first electric vehicle, Wuling Air EV, in Indonesia. This study aims to analyze the influence of the brand image of Wuling electric vehicles, brand awareness, country of origin and perceived risk on the purchase intention of Indonesian consumers. Data collection in this study was carried out through offline and online questionnaires which were distributed to 150 respondents who met the research criteria in the JABODETABEK area, and they all owned cars and had driving experience. Partial Least Squares-Structural Equation Modeling (PLS-SEM) was adopted for data analysis. The results of this study indicate that country of origin, perceived risk, and brand image have a significant effect on consumer purchase intention. In addition, perceived risk also has a significant positive impact on brand image. However, the influence of country of origin and brand awareness has no significant effect on brand image. 展开更多

为探究低温胁迫下小麦幼穗中胁迫响应差异表达蛋白,采用IEF/SDS-PAGE双向凝胶电泳及质谱技术,以低温敏感品种SW601和低温不敏感品种陇麦157为材料,对常温生长、0℃低温胁迫12h和72h的幼穗全蛋白进行了分析。结果表明,在pH4~7时,S... 为探究低温胁迫下小麦幼穗中胁迫响应差异表达蛋白,采用IEF/SDS-PAGE双向凝胶电泳及质谱技术,以低温敏感品种SW601和低温不敏感品种陇麦157为材料,对常温生长、0℃低温胁迫12h和72h的幼穗全蛋白进行了分析。结果表明,在pH4~7时,SW601和陇麦157各处理幼穗蛋白图谱中均可重复检测到800900个有效蛋白质点;低温胁迫12h、72h后,SW601和陇麦157中上调表达的蛋白点分别有120个和101个,下调表达的蛋白点分别有92个和60个。对2种胁迫处理下均差异表达且Ratio〉2的54个蛋白点进行质谱分析,成功鉴定出43个差异蛋白。经数据库搜索匹配和蛋白质鉴定,这43个差异蛋白分别属于胁迫应激/防御相关蛋白、光合作用蛋白、蛋白代谢相关蛋白、碳水化合物代谢相关蛋白、信号传导相关蛋白、能量产生和运输相关蛋白和未知功能蛋白等7类蛋白。其中,抗坏血酸过氧化物酶、Cu/Zn超氧化物歧化酶和胚胎后期发育富集(LEA)同源蛋白14-A等蛋白的表达量在低温不敏感材料陇麦157中变化显著,而在低温敏感材料SW601中没有表达,这可能与小麦幼穗在低温逆境下的代谢调控和低温敏感特性有一定关系。 展开更多
