查询词典 sensitivity threshold

The genetic study suggested that the carbendazim-resistance in these mutants could be steadily inherited by asexual and selfed reproduction, and the resistance was controlled by the same single major gene both in laboratory mutants and field resistant isolates, the different levels of resistance or the same resistant level in different strains maybe conferred by mutations at different sites or one site with different allelic mutations. The gene compensates for the sensitivity to MDPC was allelic to that governs the carbendazim resistance, but the mutation for increasing sensitivity to MDPC in this gene could get the pathogen highly resistant to carbendazim.

抗药性遗传研究表明，在所研究的抗药突变体中，抗药性在自交和无性繁殖后代中能稳定遗传；室內抗药突变体和田间抗药菌株对多菌灵的抗药性由同一个主效基因控制，但它们发生突变的位点不同或者同一碱基位点发生了不同的突变；对MDPC的敏感性也是由单个基因控制的，该基因与控制多菌灵抗性的基因是等位基因，当该基因发生对MDPC的敏感性增加的突变时会使病菌对多菌灵产生高水平抗性。
