vir助记

According to the studies on distribution of A. tumefaciens on plant cell walls, the expression of vir gene, and the transient expression of gus gene, the feasibility of this method for transforming to barrel medic was tested.

另外，通过对农杆菌在植物细胞壁上的吸附、vir基因的表达及gus基因的瞬时表达的研究，初步探讨了该法对截型苜蓿遗传转化的可行性。

Our data indicated that the A. tumefaciens cells grew well inside the floral tissues and the expression levels of vir genes were also high, during the six floral stages.

研究表明，接种的六个时期农杆菌存活都很好，vir基因表达水平也很高；

The goal of exploiting vir tu al manufacture system makes virtual production environment, it can analyze capa bility of virtual production.

开发虚拟制造系统的目标是为虚拟制造建立一个虚拟的制造环境，用于仿真和评估各制造过程对产品质量的影响。
