Abstract:
首次采用气象色谱法,开展两个膏桐新品种——多花膏桐和皱叶黑膏桐籽油得脂肪酸组成分析;同时,又以竹碳基固体酸为催化剂,以膏桐新品种(包括多花品种和皱叶黑品种)籽油为原料,探讨竹碳基固体酸在膏桐籽油酯化反应中的催化效应,测定了不同膏桐新品种籽油炼制生物柴油的效率。测定结果表明,膏桐新品种籽油脂肪酸的组成重要是棕榈酸、棕榈油酸、硬脂酸、油酸和油酸,品种间的差异主要体现在脂肪酸组成的相对比例的变化上,因此可作为膏桐植物种群进化的评价依据;膏桐新品种籽油炼制生物柴油的效率分别为多花膏桐89.68%、皱叶膏桐86.50%、西双版纳(勐仑)地方品种87.12%,其主要成分是棕榈酸甲酯、油酸甲酯和亚油酸甲酯。品种间的差异亦主要体现在脂肪酸甲酯组成的相对比例的变化上。
Analysis of compounds of high-acid oil extracted with machine from two new jatropha cultivar seed had been carried out by Gas Chromatography (GC) since 2010. At the same time, using bamboo carbon base solid acid as a catalyst and the new jatropha cultivars seed oils as raw materials, impact factors of esterification reaction had been investigated, and esterification rate of the jatropha cultivars seed oils and main fatty acid compounds were also determined by GC. The results showed that the jatropha cultivars oils are mainly composition of palmitic acid, palmiticoleic acid, stearic, oleic and linoleic. Differences between both the seed oils of the different jatropha cultivars found mainly expression in the relative ratio of different fatty acids, indicating that a significant change in the relative ratio of the different fatty acids can be considered as an evolutionary evidence of jatropha population. On the basis of jatropha seed oils with high-acid value, esterification of the new jatropha seed oils was carried out using bamboo carbon base solid acid as a catalyst, and had achieved esterification rates of 86.5% - 89.7%. The products of the esterification are mainly composed of palmitic acid methyl, oleic methyl and linoleic methyl, and difference between these jatropha cultivars also found expression in the relative ratio of different fatty acid methyls. Black winkle-leafed jatropha cultivar is distinctive to the other two cultivars, which in the front rank of the fatty acid methyls is linoleic methyl that is the highest (42%) followed by oleic methyl (36%) and stearic methyl (16%), whist rank of other two cultivars is oleic methyl (42%) that is highest followed by linoleic methyl (36%) and stearic methyl (16%).

Abstract: 随着现代计算机科学技术的不断发展,labview图形编程自2011年以来,元江干热河谷进行了巴西油藤的引种试验。试验结果表明,与先前西双版纳引进的秘鲁油藤(Plukenetia volubilis cv. peruvian, PVP)比较,巴西油藤(Plukenetia volubilis var. brazilian, PVB)有较强的适应性和较高的生产潜力。二者相比,巴西油藤(PVB)对元江干热河谷具有比较好的适应性和生物学特异性。其特异性表现为不易染病,雌花花柱比较短,种籽粒小、皮薄,种子含油率为35.4%,高于秘鲁油藤(34.1%) 1.4个百分点;通过机械压榨,种子油的得率为30%。小区试验3年生时种子亩产量为88.5 kg,折合每公顷1327.5 kg/ha,可产精油367.1 kg/ha。从这些数据来看,巴西油藤在云南干热河谷区生物产业发展中有良好的应用前景。
Since 2011, an introduction test of Plukenetia volubilis var. brazilian (PVB) has been carried out in arid-hot valley of Yuanjiang, Yunnan. The results showed that compared with Plukenetia volubilis var. peruvian (PVP) introduced in Xishuangbanna previously, PVB has a strong adaptability and high production performance. Its advantages lie in not infected, style short, thin shell, small grain, high rates of seed oil. According to determination, PVB seed oil content (35.4%) was slightly higher than PVP (34.1%), and obtained seed oil content of 30% by mechanical pressing and on small field test, seed yield reached 1327.5 kg/ha and oil yield of 367.1 kg/ha at 3-year-old growth. It is suggested that PVB has a good perspective for bio-industry development in the dry-hot valley of Yunnan.

Abstract: 用长度为21bp的一对β-葡糖苷酸酶(gus)基因的pcr引物,从根癌农杆菌lba4404细胞总dna中扩增不出任何片段,但从合pbi121的lba4404细胞总dna中可扩增出一条预期大小(1.2kb)的gus基因片段,这表明根瘤农杆菌lba4404不含内源gus基因.
水稻小G蛋白OsRab5b的亚细胞定位研究

生物技术通报 , 2015, DOI: 10.13560/j.cnki.biotech.bull.1985.2015.11.017
Abstract: 旨在研究水稻OsRab5b亚细胞定位及第二位甘氨酸在蛋白定位中的作用。利用药物、细胞器标记物和示踪染料处理OsRab5b-GFP与OsRab5b(Gly2Ala)-GFP的转基因BY-2细胞,然后用激光共聚焦显微镜观察。结果表明,OsRab5b-GFP转基因细胞呈现出大量的分散点状结构和少量细胞质弥散信号;wortmannin处理可以使OsRab5b-GFP标记的点状结构膨胀成小的环状结构;采用100μg/mL布雷菲德菌素A(BFA)处理可使OsRab5b-GFP标记的结构聚集。大部分的OsRab5b-GFP信号都可以与前液泡区标记蛋白VSRAt-1共定位。在内吞示踪染料FM4-64摄取的第60min,OsRab5b-GFP标记的结构大部分被FM4-64标记。突变体OsRab5b(Gly2Ala)-GFP弥散分布于细胞核和细胞质内,而且不受wortmannin或BFA药物处理的影响。OsRab5b定位于BY-2细胞的前液泡区,Gly2在蛋白准确定位方面发挥重要作用。

Abstract: Lamb波技术非常适于板类结构的各种缺陷检测。为了得到模态较为单一的Lamb波,使得接收信号更具有解释性,缺陷更容易识别,该文中在板上下表面的相同位置分别布置压电传感器阵列,采用同一位置上下表面的双压电片同相或反相激励,激励出单一S0或A0模态。运用这种单模态的Lamb波激励方式对板中缺陷进行检测,结合椭圆成像算法与数据融合方法对压电传感器阵列接收到的多组信号进行缺陷成像。该方法有效的实现了板中缺陷的二维成像定位,检测出人工缺陷,并提高了缺陷的可识别能力和定位精度。
