远缘杂交

说明辐照外源DNA导入番茄技术效果好，重复性好，便于进行远缘杂交。

All mentioned above shows that the method of introducing radiated exogenous DNA into tomato has desirable effect and repetition , which can be used to facilitate distant hybridization .

结果表明：利用花粉管通道直接导入外源DNA是改良黄瓜品种的有效技术，这一技术将在作物品种改良及远缘杂交方面起着非常重要的作用。

The result of preliminary studies indicated that the method of directly introducing exogenous DNA into the cucumber through the pollen tube pathway is very valuable for improving cucumber characters , It is very important in improving the crop varieties and the distant hybridization .

植物远缘杂交可以引起广泛的表观遗传变异，如：基因沉默、核仁显性、转座子激活、DNA甲基化变异等，而DNA甲基化尤其是胞嘧啶甲基化是表观遗传的主要调控机制之一。

Distant hybridization of plants can cause a wide range of apparent genetic variability , such as : gene silencing , nucleolar dominance , transposon activation , DNA methylation variations and so on , and DNA methylation , in particular cytosine methylation is one of the main epigenetic control mechanisms .
