水稻体细胞杂交研究进展

Practice and Prospects of Somatic Hybridization on rice

水稻是世界重要的粮食作物 ,全世界约有 12 0个国家种植水稻。水稻的近缘或远缘种具有一些优良性状 ,如抗病、抗虫、抗逆等。将这些性状导入水稻 ,是科学家们所希望的 ,但因用普通杂交方法存在交配系统的不亲和性等难题而进展不大。随着组织培养技术的发展 ,特别是植物原生质体培养技术的日趋成熟 ,使得人类能够在细胞水平通过体细胞杂交方法实现遗传信息的重组。

A review of somatic hybridization on rice is presented in this paper. The main contents are: the brief history,development and current status of somatic hybridization on rice; the obtainment and identification of somatic cell hybrids on rice;the appliciation of somatic\|hybridization technology in the genetic manipulation of rice.The further prospects of somatic hybridization on rice have also been discussed.
