1一个白菜型油菜细胞质雄性不育的遗传研究(英文)显示文摘1993年春在白菜型油菜品种“浠水白”中发现了几株雄性不育株。遗传研究结果表明,“浠水白”雄性不育株为细胞质雄性不育,所有调查过的白菜型油菜品种(系)均是这种雄性不育的保持系。与pol CMS和nap CMS的保持系和恢复系的测交结果表明,“浠水白”雄性不育与nap CMS具有相同的恢保关系,与pol CMS具有完全不同的恢保关系。EcoR I、HindⅢ、Pst I和Sal I四种限制性内切酶的线粒体DNA酶切图谱及以atp6和orf222作探针的RFLP分析结果显示,“浠水白”的细胞质与nap CMS相同,而与pol CMS不同。杨光圣 傅廷栋 Gregory G.Brown 1998作物学报1998,24,6:3

10Assistant Anode in a Cathodic Arc Plasma Source显示文摘The performance and characteristics of a cathodic arc plasma source,consisting of a titanium cathode,an anode with and without a tungsten mesh,and a coil producing a focusing magnetic field between the anode and cathode,are investigated.The high transparency and large area of the mesh allow a high plasma flux to penetrate the anode from the cathodic arc.The mesh helps to decrease the arc resistance and the ignition voltage of the cathodic arc in the focusing magnetic field,and increase the life of the source.which means that the source makes the cathodic arc easily and greatly stabilized during the operation when a focusing magnetic field exists in the source.张涛 张荟星 Ian G.Brown Paul K.Chu 2001Chinese Physics Letters2001,18,8:0
11Cryo-EM structure of the plant 26S proteasome显示文摘Targeted proteolysis is a hallmark of life.It is especially important in long-lived cells that can be found in higher eukaryotes,like plants.This task is mainly fulfilled by the ubiquitin–proteasome system.Thus,proteolysis by the 26S proteasome is vital to development,immunity,and cell division.Although the yeast and animal proteasomes are well characterized,there is only limited information on the plant proteasome.We determined the first plant 26S proteasome structure from Spinacia oleracea by single-particle electron cryogenic microscopy at an overall resolution of 3.3 A°.We found an almost identical overall architecture of the spinach proteasome compared with the known structures from mammals and yeast.Nevertheless,we noticed a structural difference in the proteolytic active b1 subunit.Furthermore,we uncovered an unseen compression state by characterizing the proteasome’s conformational landscape.We suspect that this new conformation of the 20S core protease,in correlation with a partial opening of the unoccupied gate,may contribute to peptide release after proteolysis.Our data provide a structural basis for the plant proteasome,which is crucial for further studies.Susanne Kandolf Irina Grishkovskaya Katarina Belacic Derek L.Bolhuis Sascha Amann Brent Foster Richard Imre Karl Mechtler Alexander Schleiffer Hemant D.Tagare Ellen D.Zhong Anton Meinhart Nicholas G.Brown David Haselbach 2022Plant Communications2022,3,3:0
12匙吻鲟精液的贮藏与运输显示文摘匙吻鲟(Polyodon spathula)是一种重要的商业养殖品种,美国大多数联邦和州的孵化场都为此制定了恢复原种和原种增殖的计划,因而提前采集匙吻鲟精液并贮藏以备受精之用不失为一种简便易行的方法。Gorge G.Brown Steven D.Mims 冯云 刘学迅 1999北京水产1999,,2:0
