植物资源、绿色基因与发展中国家的食物安全

Plant Resource, Green Gene and Food Security & Safety in Developing Countries

2 0世纪 6 0年代以来 ,全球第一次“绿色革命”为改善发展中国家粮食供应做出重大的贡献。进入 2 1世纪 ,发展中国家面对由于资源衰退和环境破坏带来的食物数量和质量安全的双重挑战 ,充分发掘本国植物资源的“绿色基因”,以提高资源利用效率、改良环境 ,从而提高作物产量 ,以及修复污染环境 ,提高植物性食品的营养和卫生品质 ,保障食品安全。文章最后评述了国内外与保障食物安全相关的绿色基因工程研究和开发的最新进展。

The first green revolution worldwide since 1960s had made great contribution to global food supply especially in developing countries. In the beginning of 21 century, however, developing countries is confronting to the severe double challenge of food security and safety due to nature resource degradation and environment contamination. The way to safeguard food security and safety in developing countries is to exploit the green genes in plant germplasm resource that can increase the efficiency for utilization of nature resource, improve environment status , eliminate environmental pollutants and enhance the nutrient and sanitary quality of crop production. the latest advances both nationally and internationally in cloning and transformation of green gene concerning to food security and safety from plant resource is addressed in last section of the paper.
