susceptible strain

More than double mutations in different codons of one rifampin-susceptible strain were also detected, this may be the effect of suppressor mutation.

还发现在两株利福平敏感菌株的rpoB基因中也存在两处以上的突变位点，并分别位于不同的氨基酸密码子中，这可能是第二位点突变对菌株耐利福平突变产生抑制的结果。

Meanwhile, V _ ( max ) values were approximately four times as high for DDVP-R compared with the susceptible strain.

同时, DDVP -R 品系中V_ ( max ) 大约是敏感品系的4倍,说明该抗性品系中GSTs对GSH的 亲和力虽然下降,但是其可以通过V_(max)的提高来弥补亲和力下降所造成的损失.

The supercooling points ( SCP), freezing points ( FP), moisture content, fat content, content of glycogen were no differences between resistant and susceptible strains when they fed normal artifical diet, so the cold hardiness was no difference between resistance and susceptible strain.

抗、感品系在正常人工饲料饲养条件下的过冷却点、冰点、含水量、脂肪含量、糖原含量没有差异，因此抗、感棉铃虫的抗寒性没有差异。

In the same condition in laboratory, LD50 or LC50 of 3rd instar larva of susceptible strain and Lambda-cyhalothrin resistant strain of beet armyworm were determined.

研究结果如下：1、在室内相同条件下，分别用点滴法和浸叶法测定甜菜夜蛾抗氯氟氰菊酯品系和敏感品系3龄幼虫LD50（ug/头）或LC50值（mg/L）。

The resistant strain possessed 0.84 of fitness value relative to the isogenic susceptible strain.

种群适合度研究表明,抗性品系相对于敏感品系有0.84的适合度.

The detection of susceptible and resistant strain and their backcrossing heterozygosis with PCR in laboratory validate above presumption.

室内用抗性和敏感亲本及正交杂合子检测的结果验证了上述推测。
