The new tomatoes could improve the nutritional value of everyday foods


(CC By 2.0)  By introducing a gene from the snapdragon, genetic engineers have imbued the tomato with the healing cancer-fighting power of compounds nature placed in less popular (and more expensive) fruits, such as blackberries and cranberries. Note: This photograph illustrates the concept of a purple tomato.

Purple GMO Tomatoes 'Healthier' Than Nature, Coming Soon To Grocery Shelves In Canada, UK

   通过基因改造可以使西红柿的颜色发生改变,提高营养价值,如英国约翰英内斯研究中心的卡西·马丁(Cathie Martin教授等人,他们先从金鱼草中提取基因植入一批西红柿,将它们培植成能自动制造花青素的新型紫西红柿。紫色西红柿可以还有在蓝莓(blueberries)和蔓越橘(cranberries)中含有的花青素类物质anthocyanins),花青素有消炎和抗癌作用,并能预防II型糖尿病。关于基因改造西红柿的相关信息(主要来自《GO Compass网站)摘录如下,供大家参考。
