Abstract

Cells infected with temperature-sensitive (ts) mutants of complementation group V of vesicular stomatitis virus (VSV) give an enhanced yield at nonpermissive temperature when co-infected or superinfected with UV-irradiated virus. Virions produced in these mixed infections are temperature sensitive and do not complement ts V45. Rescue of group V mutants is multiplicity dependent. It can occur in the presence of cycloheximide; kinetics of rescue are similar in the absence or in the presence of the drug. Rescue is due to nongenetic complementation and is interpreted as a trigger effect on maturation of a small quantity of biologically active protein V molecules provided by UV-irradiated virus. These results are comfirmed by rescue of ts V45 by UV-irradiated, defective, interferring T particles.

摘要

感染水疱性口炎病毒(VSV)互补组V温度敏感(ts)突变体的细胞,在与紫外线照射的病毒共感染或超感染时,在非允许温度下产量会提高。在这些混合感染中产生的病毒粒子对温度敏感,并且不能互补ts V45。V组突变体的拯救是多倍体依赖性的。它可以在环己酰亚胺存在的情况下发生;在药物不存在或存在的情况下,拯救的动力学相似。拯救是由于非遗传互补,并且被解释为对紫外线照射的病毒提供的少量生物活性蛋白V分子成熟的触发作用。这些结果通过紫外线照射的、有缺陷的、干扰性T颗粒对ts V45的拯救得到证实。
