摘要: 辣椒农杆菌介导转化体系主要包括无菌苗制备、菌株培养、农杆菌介导转化、芽诱导、芽伸长、生根及移栽等6个步骤.芽诱导培养基以MS+.0~6.0 mg/L6-BA+0.5 mg/LNAA+2.0 mg/LAgNO3较好,诱芽分化率因品种不同而异,高的可达70%以上,子叶的分化率明显高于下胚轴;诱芽伸长培养基以MS+3.0 mg/L 6-BA+0.3mg/LNAA+1.0 mg/L GA3较好,伸长率达0%;生根培养基以1/2MS+0.3 mg/L NAA(或0.5 mg/L IAA)较好,平均生根率达65%.经过对3个品种的抗虫基因转化研究,均获得了转抗虫基因再生株.

Abstract: The transfer system by Agrobactericum-mediated for Capsicum f rutescens included six steps:preparation of sterilize plant, culture of bacteriaLstrain, transformation by Agrobacterium-mediated, shoot induc-tion, shoot elongation, root induction and transplanting.A better shoot induction medium was MS+4-6mg/L6-BA+0.5mg/LNAA+2.0mg/LAgNO3, the frequency of shoot regeneration was different with various breeds, and the highest frequency reached more than 70%.The cotyledons frequency of shoot regeneration was obviously higher than the hypocotys.A better shoot elongation medium was MS+3.0mg/L6-BA+0.3mg/LNAA+1.0mg/LGA3and the elongation ratio was 40%.T he medium 1/2 MS+0.3mg/LNAA(or 0.5mg/LIAA) was much suitable for root induction and the average ratio may reach 65%.Plants with insect-resistant gene had been obtained through the study on three Capsicum f rutescens breeds with the method of Agrobacteri-um-mediated.
