| 摘 要： | 将参与柿果实低氧胁迫响应的异源基因DkERF9转化到切花菊‘九月九’植株中，经PCR检测，获得了5株过量表达（35S︰︰DkERF9）的阳性植株。进一步比较分析了35S︰︰DkERF9植株与野生型植株的耐淹水性，发现水培低氧胁迫处理2周后，35S︰︰DkERF9植株较野生型植物生长缓慢，根系生长和茎的伸长均受到显著抑制，叶片颜色较淡；移除水培低氧胁迫处理3周后，生长部分恢复，但是叶片颜色及整体长势均弱于野生型植株。

| Abstract: | The exogenous DkERF9，a reported hypoxia responsive gene from persimmon，was transformed into‘Jiuyuejiu’chrysanthemum. Five positive lines（35S::DkERF9）were obtained and verified with PCR. Compared to the wild type plants，the growth of 35S::DkERF9 lines were inhibited significantly by water planting treatments for two weeks，as the length of roots and shoots were shorter in 35S::DkERF9 lines. The differences between 35S::DkERF9 lines and wild type plants remain significant，after three weeks recovery. |
