【摘要】 草莓是世界上重要的水果之一。现代生物技术的不断发展为草莓育种和种质创新提供了新的技术手段,它可以直接将来自不同种属的异源目的基因插人到草莓基因组,使草莓表达目标性状,实现草莓品种的遗传改良。近年来,国内外草莓转基因研究取得了重大进展。文章综述了草莓转基因研究在抗病毒、抗虫、抗除草剂、抗逆及品质改良等方面的最新进展,分析了草莓转基因研究中存在的主要问题,并对今后的研究方向和应用前景进行了讨论。更多还原

【Abstract】 Strawberry(Fragaria ananassa Duch.) is one of most important fruit crops cultivated widely in world.Genetic transformation has launched a new era in strawberry breeding and germplasm creativity.It offers a direct method of creating varieties that selectively targets gene or a few heterologous traits for introduction into the strawberry plant.Great advances have been made in strawberry genetic transformation in the past years.This paper reviews the recent progress in genetic transformation of strawberry on promoting resistance to viruses and fungi,insects,herbicides,stress and quality improve-ment.Problems and the prospects for application of genetic transformation in strawberry were discussed.更多还原
