Vascular endothelial cell growth factoris a kind of glucoprotein ,which has separated by culturing stellate cells of bovine glandula pituitaria in vitro by Ferrara etc. in 1989.lt can express that anxo-act vascular endothelial cell growth specificly and induce vasotropic growth ,so it is called VEGF.

血管内皮细胞生长因子(Vascular endothelial cell growth factor)是1989年Ferrara等牛垂体星状细胞体外培养分离出的一种糖蛋白，其在体内外都表现出特异性地促进血管内皮细胞的生长并诱导血管生成作用，故此称为血管内皮细胞生长因子。

结果表明：适合河南省的当家草种有10种，分别是：紫花苜蓿、沙打旺、苇状羊茅、多年生黑麦草、小冠花、红三叶、杂三叶、鸡脚草、无芒雀麦；适合河南省草业优质发展的草种区域有6个，分别是：豫北平原牧草种植区、豫西北黄土丘陵和太行山地种植区、豫中东低洼平原和南阳盆地种植区、豫西山地种植区、淮南与桐柏山区种植区、豫东平原种植区，并且明确了各区域内以当家草种为核心的草种优化组合。河南省当家草种的制定和草种区划的确定有利于为河南省各地草种的正确选择和草业未来大发展提供理论依据。

The research and development of nano-plant fines proceed rather slowly, and the health foods of natural plants such as nanopollen and auricula, the rare medicinal plants such as ginseng, glossy ganoderma, pearls and cordyceps sinensis and the toxic medicinal plants such as strychnos nux-vomica are all in their development stage owing to the scientific and technical problems.

纳米植物粉体产品研发进展缓慢，如纳米花粉，木耳等天然植物保健食品，人参，灵芝孢子，珍珠，冬虫草等名贵药用植物，以及如马钱子等有毒药用植物的纳米植物粉体产品尚处在开发阶段。这里既有科学问题，也有技术问题。

But wait until the plants are completely dry before picking beans. Picking beans from wet plants can spread bean bacterial blight, a disease that damages the plants.

Three kinds of plant expressing vector pC1304- CamV35S+ Cbcor15b, pC1304-cold-induced promotor+ Cbcor15b*, pC1304- CamV35S+ Cbcbf for transforming dicotyledon plants was constructed successfully by substituting the report gene of pC1304 with the coding sequence of our destination gene. The recombinant vector was introduced into Agrobacterium tumefaciens with freeze-thaw method. The leaf discs of tobacco plants infected by A. tumefaciens were selected with hygromycin. The regenerated plants were tested by PCR.

在成功的构建pC1304- CamV35S+Cbcor15b，pC1304-冷诱导启动子+Cbcor15b*，pC1304- CamV35S+ Cbcbf三种植物表达载体之后，采用冻融法成功地将重组质粒转化到了根癌农杆菌菌株EHA105中，采用农杆菌介导的烟草叶盘转化法，将荠菜Cbcor15b，Cbcor15b*，Cbcbf，转入模式植物烟草中，在诱导生根后对转基因苗进行了PCR检测。
