This developed a new material for the wheat virus-resistance breeding.In order to breed maize dwarf mosaic disease梤esistance maize species, the PAP gene was introduced into maize inbred strains and hybrid strains mediated by pollen and particle bombardment,10 transgenic maize plants were achieved and the PAP gene was indeed integrated into the maize genome by analysis of molecular biotechnological methods. The PAP gene in one of the transgenic maize plants had been transcription and translated, the ability of the virus resistance is undergoing.

为了解决玉米矮花叶病害的防治问题，采用花粉介导法及基因枪法将PAP基因分别导入玉米的杂交种及自交系，获得了10株转基因玉米，PCR及Southern-blot检测结果表明PAP基因已经整合到了玉米基因组中，并且其中有一株PAP基因已经得到了表达，病毒抗性鉴定表明转基因玉米能明显推迟玉米矮花叶病害症状的表现。

A 1.8 kb fragment of 3' terminus of the viral RNA was amplified by RT PCR, cloned and its sequence was determined. Sequence comparisons showed that it shared 71.5%～99.1% homology with isolates of sugarcane mosaic virus, 67.8%～68.5% with sorghum mosaic virus and 38.4%～48.4% with maize dwarf mosaic virus, indicating that the pathogen of this disease on maize in Hangzhou was sugarcane mosaic virus.

病毒RNA13'端序列(1.8kb)与甘蔗花叶病毒同源性最高，达 71.5 %～ 99.1%，与高梁花叶病毒同源性次之，为 6 7.8%～ 6 8.5 %，与玉米矮花叶病毒同源性最低，仅为 38.4%～ 48.4%，从而初步认为此病害由SCMV引起。
