玉米籽粒蛋白质含量和赖氨酸含量较低,而作为蔬菜之一的茄子果实,这两种营养元素就更低。在食用植物中含蛋白质量丰富的可以说是大豆,其赖氨酸含量也很高,可与禾谷类成营养互补。因此,在进行作物品质改良的育种中,可以利用大豆这一优良特性,将其高蛋白,高赖氨酸含量的遗传因子转移到禾本科或蔬菜等作物中,来提高其营养价值。 我们从1988年开始,利用花粉管通道途径,将外源大豆DNA直接导入茄子和玉米,现简报如下: Maize grain protein content and lysine content is low, and as one of the vegetables, eggplant fruit, these two nutrients even lower. In food plants rich in protein content can be said that soybeans, the lysine content is also very high, with cereals into nutritional complementarity. Therefore, in the breeding of improved crop quality, the good characteristics of soybean can be utilized to transfer the high-protein and high-lysine genetic elements into grasses or vegetables and other crops to enhance their nutritional value. Since 1988, we have used the pollen tube pathway to direct the introduction of exogenous soybean DNA into eggplant and corn. The briefing is as follows:
