用糜子蔗(sorghum×sugarcane)×millet sorghum茎尖愈伤组织为受体,通过基因枪轰击将Bar基因转入糜子蔗细胞;用除草剂Basta含量分别为1、2.5、5、10mg/L的8114诱导与分化培养基上选择抗性愈伤组织;在Bast a含量为1与1.5mg/L筛选培养基上,选择出3个快速增殖并大量再生绿苗的体细胞无性系(Clone),如BarC1、BarC2、BarC3;BarC1、C2再生植株用Basta含量为1、2.5-5mg/L的溶液进行抗性检测,证明这些小植株具有极强的抗性。
Abstract:The Bar genes were introduced into〔(sorghum×sugarcane) ×millet sorghum〕callus cells using particle bombardment.The callus were cultured on the 8114 media with Basta,the Bastas concentration is 1,2.5 and 5,10mg/L.3 Clones with regenerated capacity were screened out on the media with Basta 1,2.5mg/L,for example BarC1,BarC2,BarC3.The regenerated plant from BarC1、BarC2 were cultured on the solution with Basta 1.5,2.5,and 5mg/L,high resistance were obtained in these regenerated plants. 相似文献
