This trend is making the testing and development of many crops with commercial and humanitarian potential economically unfeasible. Despite robust laboratory research on plants since the invention of modern genetic-engineering techniques in the early 1970’s, the commercialization of products has lagged.
这一趋势让许多具有商业和人道潜力的作物试验和开发不再具有经济可行性。尽管自20世纪70年代初现代基因工程技术发明以来，实验室研究一直相当鲁棒，但产品商业化情况一直停滞不前。
