永利总站公司产光合作用测定仪数据被SCI杂志采用

    2013年，科研杂志 Plant Biotechnology Journal(2013)11,pp 380-389，发表了题为Increased expression of phospholipase Da1 in guard cells decreases water loss with improved seed production under drought in Brassica napus 的研究报告。该研究报告中有关植物叶片气孔导度（stomatal conductance）和水分传输（Water transpiration）两项测量所采用的仪器为北京永利总站科技有限公司研发和制造的Yaxin-1102便携式光合蒸腾仪。

      这一事实表明了我公司光合仪类产品的整体设计性能和制造水平达到了相对的水准。其数据的可靠性和真实性被科研界所承认。该型号仪器目前在中科院各相关实验室，各省市农林科研单位和各类高等大专院校中得到应用。

文章摘要：

   The activation of phospholipase Da1 (PLDa1) produces lipid messenger phosphatidic acid and promotes stomatal closure in Arabidopsis. To explore the use of the PLDa1-mediated signalling towards decreasing water loss in crop plants, we introduced Arabidopsis PLDa1 under the control of a guard cell–specific promoter AtKatIpro into two canola (Brassica napus)c*rs.Multiple AtKatIpro::PLDa1 lines in each c*r displayed decreased water loss and improved biomass accumulation under hyperosmotic stress conditions, including drought and high salinity.

  Moreover, AtKatIpro::PLDa1 plants produced more seeds than did WT plants in fields under drought. The results indicate that the guard cell–specific expression of PLDa1 has the potential to improve crop yield by enhancing drought tolerance.

   根据2013年ISI发布的JCR（Journal Citation Reports）数据，2012年Plant Biotechnology Journal 的影响因子为6.279，在总计197种期刊的植物科学（PLANT SCIENCES）学科中*9位；在总计160种期刊的生物工程和应用微生物（BIOTECHNOLOGY & APPLIED MICROBIOLOGY）学科中*12。
