摘要: 以铁皮石斛原球茎为受体,用农杆菌介导1-氨基环丙烷-1-羧酸氧化酶(ACO)的反义基因对铁皮石斛进行遗传转化,并对影响转化的几个因素进行优化,结果表明:经刀切法处理的原球茎,在AS浓度为100 μmol/L、农杆菌菌液OD600值为0.8的条件下侵染30 min,共培养60 h,接种到含有30 mg/L Mer 和3.0 mg/L PPT的筛选培养基中,遗传转化效率最高。筛选获得的抗性植株经GUS组织化学染色和PCR鉴定,初步证明ACO反义基因已整合到铁皮石斛的基因组中。

Abstract: The ACO antisense gene was transformed into the protocorms of Dendrobium officinale by Agrobacterium mediation.To optimize the transformation efficiency, several related factors were studied in this paper.The results showed that, after infected for 30 min at 100 μmol/L of AS, 0.8 of OD600 and 60 h of incubation in darkness, the cut protocorms gained the highest transformation rate in the medium of 30 mg/L Mer and 3.0 mg/L PPT.The selected plants were tested by PCR and GUS histochemical staining, indicating that the ACO antisense gene had been successfully integrated into D.officinale.

Key words: Dendrobium officinale, ACC oxidase, Genetic transformation, Agrobacterium tumefaciens
