Golden Rice will reach those who need it at no additional cost

Those who need the product of this new technology most are those who can least afford buying a mixed diet, rich in essential nutrients. This has been taken into consideration by the creators of Golden Rice technology, Professors Peter Beyer and Ingo Portrykus, and the crop protection company Syngenta, who have donated it for humanitarian use in developing countries, free of charge.

这是慈善活动历史上一个有名的case，因为金大米的技术涉及多项专利，不少是商业公司拥有的，其发明者经过多方的磋商，让那些公司同意把专利和金大米相关的使用权捐献给发展中国家。

• 那么我也想问一下，这种种子会不会种几代后就退化？就像杂交稻种一样？另外，这种稻米 -woth- ♀ (139 bytes) () 08/14/2011 postreply 15:54:45
