Shoot-Specific Down-Regulation of Protein Farnesyltransferase （α-Subunit） for Yield Protection against Drought in Canola

引用

Molecular Plant 2009年第1期2卷 191-200页

作者： Yang Wang Michelle Beaith Maryse Chalifoux jifeng ying Tina Uchacz Carlene Sarvas Rebecca Griffiths Monika Kuzma Jiangxin Wan Yafan Huang Performance Plants Inc. 700 Gardiners Road Kingston Ontario Canada K7M 3X9

Canola （Brassica napus L.） is one of the most important oilseed crops in the world and its seed yield and quality are significantly affected by drought stress. As an innate and adaptive response to water deficit, land plants avoid potential damage by rapid biosynthesis of the phytohormone abscisic acid （ABA）, which triggers stomatal closure to reduce transpirational water loss. The ABA-mediated stomatal response is a dosage-dependent process; thus, one genetic engineering approach for achieving drought avoidance could be to sensitize the guard cell＇s responsiveness to this hormone. Recent genetic studies have pinpointed protein farnesyltransferase as a key negative regulator controlling ABA sensitivity in the guard cells. We have previously shown that down-regulation of the gene encoding Arabidopsis β-subunit of farnesyltransferase （ERA1） enhances the plant＇s sensitivity to ABA and drought tolerance. Although the β-subunit of famesyltransferase （AtFTA） is also implicated in ABA sensing, the effectiveness of using such a gene target for improving drought tolerance in a crop plant has not been validated. Here, we report the identification and characterization of the promoter of Arabidopsis hydroxypyruvate reductase （AtHPR1）, which expresses specifically in the shoot and not in non-photosynthetic tissues such as root. The promoter region of AtHPR1 contains the core motif of the well characterized dehydration-responsive cis-acting element and we have confirmed thatAtHPR1 expression is inducible by drought stress. Conditional and specific down-regulation of FTA in canola using the AtHPR1 promoter driving an RNAi construct resulted in yield protection against drought stress in the field. Using this molecular strategy, we have made significant progress in engineering drought tolerance in this important crop species.

山东莒南玄武质角砾岩中含有大量地幔橄榄岩、下地壳麻粒岩和辉石岩等深源捕虏体,对这些捕虏体开展研究有助于深化对华北克拉通东部岩石圈组成和演化历史的认识。我们对玄武岩中的金云母和新获得的2件麻粒岩捕虏体分别开展了^(40)Ar-^(39)Ar年代学以及锆石U-Pb年龄和Hf同位素测试。玄武岩中金云母巨晶的^(40)Ar-^(39)Ar年代学结果表明莒南玄武岩的形成年龄为59.04±0.17Ma,该年龄比玄武岩基质K-Ar法获得的年龄年轻约8Myr。锆石离子探针U-Pb年龄结果显示,莒南地区下地壳麻粒岩的原岩记录了多期次岩浆活动,包括3.33Ga、2.52Ga、1.98Ga和0.76Ga。锆石激光原位Hf同位素揭示出莒南地区下地壳经历了多阶段陆壳的增生和改造,其中3.7~3.8Ga是最重要的陆壳增生期,新元古代也存在因地幔物质的加入导致的下地壳生长。麻粒岩捕虏体所反映的下地壳主要是始太古代新生陆壳经多期壳内物质重循环而成。

作为非传统稳定同位素的代表,Li同位素已被广泛应用于示踪与熔体和流体相关的地质过程。地幔橄榄岩高度不均一的Li含量和Li同位素组成特征是熔/流体与地幔橄榄岩相互作用过程中同位素分馏作用及温度下降过程中Li在矿物之间扩散分馏的结果,同位素扩散现象通常被矿物颗粒边部的组成特征所记录。由于Li在橄榄石中的扩散速度比在辉石中慢,所以大颗粒橄榄石核部的Li含量和同位素组成更能反映岩石圈地幔的组成,而辉石的组成特征更多地记录了后期的过程。大量地幔捕虏体的锂同位素组成特征研究表明,华北克拉通岩石圈地幔经历了蚀变洋壳在俯冲过程中、残留俯冲板片在深部地幔、以及上涌的软流圈所释放的不同组成的熔/流体的改造过程。由于改造作用的多阶段性和改造程度的不同,华北克拉通东部与中部地幔橄榄岩的组成特征具有系统性的差异。Li同位素与其他地球化学指标的联合示踪是未来地幔地球化学研究的发展趋势。

Chinese Rice Research Newsletter 1994年第1期2卷 3-4页

作者： WANG Deren and ying jifeng,CNRRI,Hangzhou,310006,China

We studied a new grain-cash cropping pattern composed of "barley/watermelon + waize-rice", comparing with "barley / watermelon-rice" (CKI), "watermelon-rice", (CK2). The experiment was conducted in CNRRI’s field for 3 yr, employing completely randomized design with three replications, and each plot occupied 207 m~2. The soil in the experiment field contained: N, 2.48 g. kg, quick effective P 4 mg. kg, and quick effective K 53 mg·kg. The varieties tested were Zhemai 2 (barley), Zhemi 1 (watermelon), Suyu 1 (maize), and Shanyou 63 (hybrid rice).

大陆地壳的起源、生长和改造一直都是国际地学界广泛关注的热点问题,目前仍存在一定的争议,特别体现在陆壳增生的方式和速率上.为了探讨大陆地壳的生长方式,简要综述了俯冲带及其岩浆作用和大陆地壳生长的研究成果.俯冲带可划分为洋洋俯冲带、洋陆俯冲带和陆陆俯冲带,其岩浆作用以产出弧岩浆岩为主要特征,被广泛接受为大陆地壳生长的主要方式.目前主要有两种陆壳生长的假说:玄武岩模式和安山岩模式.玄武岩模式主要通过拆沉和底垫过程来实现新生地壳向大陆地壳的演化;安山岩模式则强调陆壳直接形成于产出安山质岩浆的俯冲带岩浆弧环境.俯冲带和碰撞带等板块汇聚边界是显生宙大陆地壳生长和改造的主要位置,俯冲带岩浆作用对陆壳生长发挥着重要的作用.

作者： ying jifeng and Zhou Xinhua (Institute of geology and geophysics, Chinese Academy of Sciences, Beijing, 100029)

Located in Yantai municipality, Shandong province, Jindoushan gold deposit, a newly discovered deposit, can be easily distinguished from other types of gold deposits in Jiaodong region for its unique characteristic of large amount of galena in ore minerals. Based on the study of the chemical composition, thermoelectricity, and minor elements content, we conclude that galena is another kind of important Au-bearing, Ag-bearing minerals besides pyrite; the conductive type of galena is N type with large absolute value of thermalelectrical coefficient; metallogenic elements forming galena were derived from the wall rocks, i.e. Jingshan group, which is an association of biotite schist and garnet-biotite schist etc..
