To make good understanding for mode or degree of those factors to successful plant transformation will be of importance to the experiment design and the results analysis.

了解影响转化的各种因素对转化的影响方式及程度，对制定植物转化试验方案和分析试验结果是非常有帮助的。

The team has chosen this plant as it is easy to experiment with and carries minimal risk for spreading into the wild.

Because a field trial with a genetically engineered plant may be 10 to 20 times more expensive than the same experiment performed with a plant that has identical properties but that was modified with less precise genetic techniques, genetic engineering with the best techniques has been vastly under-used for the past 25 years.
