雅欣理儀公司產光合作用測定儀數據被SCI雜志采用

    2013年，科研雜志 Plant Biotechnology Journal(2013)11,pp 380-389，發表了題為Increased expression of phospholipase Da1 in guard cells decreases water loss with improved seed production under drought in Brassica napus 的研究報告。該研究報告中有關植物葉片氣孔導度（stomatal conductance）和水分傳輸（Water transpiration）兩項測量所采用的儀器為北京雅欣理儀科技有限公司研發和制造的Yaxin-1102便攜式光合蒸騰儀。

      這一事實表明了我公司光合儀類產品的整體設計性能和制造水平達到了相對的水準。其數據的可靠性和真實性被科研界所承認。該型號儀器目前在中科院各相關實驗室，各省市農林科研單位和各類高等大專院校中得到應用。

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.

   根據2013年ISI發布的JCR（Journal Citation Reports）數據，2012年Plant Biotechnology Journal 的影響因子為6.279，在總計197種期刊的植物科學（PLANT SCIENCES）學科中*9位；在總計160種期刊的生物工程和應用微生物（BIOTECHNOLOGY & APPLIED MICROBIOLOGY）學科中*12。
