马庆虎研究组分离了在小麦茎秆中高度表达的木质素合成关键酶基因-咖啡酸甲基转移酶基因，通过生化和转基因分析证明COMT 在控制松柏醇型木质素上发挥着重要作用，COMT基因的表达在抗倒伏小麦生长发育后期明显高于易倒伏品种，这种基因的高表达进一步促进了COMT酶蛋白和酶活力的提高，并增强了木质素的合成。

The quantity and contribution to grain starch yield of remobilized total soluble sugar from top of 2nd and 3rd nodes of wheat stem in Yumai 50 and Zhengmai 9023 were the highest, but the quantity and contribution to grain starch yield of remobilized total soluble sugar from top of 4th and 5th nodes of wheat stem of Wenmai 4 were the highest.

In order to prevent wheat stem lodging and to fertilize precisely, the experiments on the influence of phosphate and potash fertilizers on mechanical properties of wheat stem were performed with Zhengzhou-wheat 9023 as an object. Mechanical properties (such as flexural strength and flexural rigidity) of second base inter-node were measured by six treatments at five growth stages of wheat, which were jointing stage, booting stage, flowering stage, grain-filling stage and maturity stage. Nonmetallic material testing machine was used in the experiments.

为了对小麦精准施肥，提高小麦的抗倒伏能力，该文以郑麦9023为研究对象，磷钾肥配施共6个处理，分别在小麦拔节期、孕穗期、扬花期、灌浆期、成熟期等5个生长期，利用非金属材料万能试验机，对去鞘茎秆作3点弯曲试验，测试茎秆基部第2节间的弯曲强度和抗弯刚度。

阀盖：阀门的包含填料函和阀杆密封并能对阀杆进行导向的部分。

In the straight-through valve, the valve parts typically include the closure components, valve seat ring, valve cage, valve stem and the stem pins.

在直通阀体里，阀内件典型地包括截流元件、阀座环、阀笼、阀杆和阀杆销钉。

Delta gene transfer may provide a means for solving the problems of ex vivo expansion of DPSCs. The establishment of transduced DPSCs may be used as seeding cells for dental pulp regeneration or tooth engineering, and for further studies, such as the mechanisms regulating stem cells commitment and differentiation, and stem cells related gene therapy.

Delta1基因转导可能有助于解决牙髓干细胞体外培养易老化和难大规模扩增等问题；获得的基因改造牙髓干细胞一方面有望作为组织工程的种子细胞，另一方面也为进一步研究牙髓干细胞向不同方向分化机制、相关基因治疗等打下了良好的基础。
