Transgenes engineered into annual crops could be unintentionally introduced into the genomes of their free-living wild relatives. The fear is that these transgenes might persist in the environment and have negative ecological consequences. Are some crops or transgenic traits of more concern than others? Are there natural genetic barriers to minimize gene escape? Can the genetic transformation process be exploited to produce new barriers to gene flow? Questions abound, but luckily so do answers.
导入一年生作物中的转基因可能会意外地导入其野生近缘种的基因组中。人们担心这些转基因可能会在环境中留存并产生负面的生态后果。某些作物或转基因性状是否比其他作物或性状更令人担忧？是否存在天然的遗传屏障来尽量减少基因逃逸？能否利用基因转化过程来产生新的基因流动屏障？问题众多，但幸运的是答案也不少。
