与infectivity相关的网络例句 [注：此内容来源于网络，仅供参考]

The infectivity of TMV recovered by dialysis from incubation with anthraquinone glycosides in vitro has been reduced in contrast to infectivity of TMV control, it seems that anthraquinone glycosides have direct viricidal effect on TMV. The anthraquinone glycosides may interfere recognization of TMV to host receptor when applied before TMV inoculation. The anthraquinone glycosides can inhibit multiplication of TMV in infected leaf discs but did not inhibit infectivity of TMV-RNA in vitro. The control of tobacco mosaic virus disease of N.

总蒽醌甙对TMV混合，对粒体形态无破坏作用，但经透析，其抑制作用仍较高，表明总蒽醌甙与TMV结合能力强不易解离或对粒体具有直接毒害作用；总蒽醌甙预先接种可能影响病毒对侵染位点的识别，对叶圆片中的病毒具有抑制复制的作用，但在体外混合不影响TMV-RNA的侵染活性，可能与总蒽醌甙干扰病毒的衣壳装配过程或影响复制酶的活性有关。

The emodin did not inhibited multiplication of TMV in infected leaf discs or infectivity of TMV-RNA in vitro. The infectivity of TMV recovered by dialysis from incubations with emodin in vitro has regained showed that the emodin did not direct viricidal effect. The emodin did not reduce infectivity of TMV when applied before TMV inoculation.

大黄素对粒体无形态破坏作用，与TMV混合后经过透析可恢复大部分的侵染活性，体外混合不影响TMV-RNA的侵染活性，并无体内抑制复制作用，预先接种也不影响TMV随后的侵染。

The morphology of virions seems to not be change after incubated with the paeonol by electron microscope. The regained infectivity of TMV recovered by dialysis from incubation with paeonol in vitro showed that the paeonol have not direct viricidal effect. The paeonol did not reduce infectivity when applied before TMV inoculation. The paeonol in low concentration can restrain the polymerization of TMV coat protein in vitro. The paeonol did not reduced infectivity of TMV-RNA in vitro. It is proposed that the paeonol inhibited TMV by binding with TMV coat protein to interfere with recognition of a host receptor essential for infection or by interfering TMV-CP polymerization in plants. The anti-TMV activity of low molecular weight chemicals extracted from Polygonum cuspidatum were determined.

丹皮酚与TMV混合，电镜下观察对粒体形态没有影响；TMV与丹皮酚混和后透析可恢复侵染力，表明丹皮酚对病毒粒体并没有直接毒害作用；预先用丹皮酚喷施叶面不影响病毒的侵染，表明丹皮酚未干扰TMV对叶片侵染位点的识别；丹皮酚在低浓度时可阻碍TMV-CP的体外聚合，对TMV-RNA并无体外抑制侵染作用，据此推测丹皮酚对TMV的抑制作用可能主要通过其与TMV-CP结合影响病毒粒体对叶片表面侵染位点的识别，或影响体内TMV粒体的脱衣壳或TMV-CP亚基的体内聚合。
