Honghezi,Dongbi,Shieryuelongyan,etc.The results showed that the method of Calcium-alginate -embedded suspended culture shaking at50r/min was suitable for longan proto plast culture;and the optimal regeneration,with up to5%of microcolony formation,occurred when protoplasts from suspensions were cultured ...

研究结果表明，海藻酸钙包埋悬浮振荡培养(50r/min)是龙眼悬浮细胞原生质体培养的适宜培养方式，在含有多种生长调节剂的改良MS培养基(MP6)上，再生小克隆的形成频率可高达5%；采用龙眼胚性愈伤组织体胚诱导、成熟和萌发的优化方案，原生质体再生小克隆分化子叶形胚状体的频率达100%，萌发植株的频率一般大于45%。

Low levels of transcripts were also detected in other organs as well as mutant ovules by RT-PCR and Northern hybridization.

进一步的分析表明GhABC1基因在纤维细胞中的表达量很高，在子叶、叶片、茎等组织中低水平表达，在根中则检测不到其转录本。
