大麦黄花叶病毒的生物学研究Ⅳ──植物基因工程及其在大麦抗黄花叶病中的应用

BIOLOGICAL STUDIES ON THE BARLEY YELLOW MOSATC VIRUS IV──PlantGenetic Engineering & Its Application In Resistance to Barley Yellow Mosaic Disease

随着植物基因工程技术的发展能将理想的目的基因通过转基因方法导入植物细胞，最后发展优良的转基因植物。己经发现大量植物病毒基因组核苷酸序列．包括病毒外鞘蛋白基因对发展抗毒工程植物特别有效．本文简述植物抗病毒病基因工程的几种策略和综述大麦抗黄花叶病（BaYMV和BaMMV）的生物技术研究现状。

Plant transformation techniques have enabled the introduction of selected genes into plants to confer novel phenotypes. A number of plant virus nucleotide sequences, including the virus coat protein gene,have been found to be paticutarly effective in the development of virus-rcsistant plants. This article briefly described the possible stratages for genetic engineering of plant virus-resistance and reviewed the biotechnological studies on resistance to BaYMV and BaMMV in Barley
