The genotype is a main factor in the genetic transformation via agrobacteriwn - mediated. the results of orthogonal experiments of the factors which affect mainly the transformation illuminates that the erniuxin genotype + bacterium 15 x + explant + dip - dye is the best one. the cocultivation time is 28 days. the experiment shows that : the erniuxin cotyledon regeneration frequency is very high, and that the dongnong901 hypocotyl regeneration frequency is very high
確立了農桿菌介導轉化過程中基因型是影響轉化率的主要因素。通過極差分析，基因型為「二牛心」 ，菌液濃度15倍的，外植體為子葉，感染方法為浸泡法是最佳的組合。農桿菌與外植體共培養的時間為28h 。 -
Comparing the two genotypes, the frequency of callus induction and green plant regeneration was less affected for tolerance - genotype
耐病基因型的愈傷組織誘導率和綠苗分化率的降低幅度均小於感病材料。 -
Our results showed as follows : 1 ) the spl and rsal polymorphisms of the collagen type 1 alpha 1 ( col1 al ) gene, the - 174g / c promoter polymorphism of the interleukin - 6 ( il - 6 ) gene, the asn363ser polymorphism of the glucocorticoid receptor ( gr ) gene, and the t ? c polymorphism in intron 5 of the transforming growth factor pi ( tgf - p ! ) gene are absent or too rare in chinese. compared the polymorphisms of these five markers with other populations using % 2 test and fisher ' s exact two - tailed test, significant differences of allele and genotype frequency distributions were observed at these polymorphisms ( p < 0. 001 )
結果表明： 1 ）白介素6 （ il ? 6 ）基因的? 174g c多態性、型膠原蛋白_ 1 （ col1a1 ）基因的sp1和rsa多態性、轉化生長因子_ （ tgf - _ 1 ）基因的內含子5t c多態性和糖皮質激素受體（ gr ）基因的asn363ser的多態性在中國人群中均未發現或者多態性很低； x ~ 2檢測和fisher精確（雙尾）檢驗比較這些多態性的頻率，發現在中國人群與其它種群或人群中，等位基因和基因型存在顯著的差異（ p 0 . 001 ） 。 -
