摘要
以栽培大豆 [Glycinemax (L .)Mer]吉林 30、吉林 43、绥农 8、黑农 35和东农 42等的下胚轴为外植体 ,用EHA10 5和LBA44 0 42个根癌农杆菌菌株 (分别含有 pGBI12 1S4ABC和pGBI4A2B质粒 )研究大豆基因型对根癌农杆菌的敏感性 ,以及根癌农杆菌对大豆的侵染能力。结果表明 ,大豆基因型对根癌农杆菌的敏感性存在显著差异 ,以吉林 43最敏感。根癌农杆菌菌株对大豆下胚轴侵染能力不同 ,含有 pGBI12 1S4ABC质粒的LBA44 0 4侵染能力较强 ,但差异未达显著水平。
The sensitivity of genotypes in soybean to lines of Agrobacterium tumefaciens and the ability of A.tumefaciens infecting to soybean were investigated with hypocotyls of soybean (Jilin30,Jilin43,Suinong8,Heinong35 and Dongnong42) and lines of A.tumefaciens LBA4404 and EHA105 which including plasmid pGBI121S4ABC and pGBI4A2B respectively.The results showed that the sensitivity of genotypes in soybean to A.tumefaciens was significantly different.Jilin43 was the most sensitive materials to A.tumefaciens .The ability of A.tumefaciens infecting hypocotyls in soybean was different.LBA4404 including plasmid pGBI121S4ABC was easier to infect hypocotyls of soybean.
