谢谢能人帮我翻译一下下面这段话
2 No remarkable differences in symptoms among the isolates were observed on the systemic hosts N. benthamiana and N. tabacum Samsum NN. However, the isolates could be classified into four pathotypes based on their ability to infect and cause symptoms on N. glutinosa. All isolates were able to infect N. glutinosa, except five collected from Indonesia and two from India, which were not infectious on this host. Three parameters were evaluated at 14 d.p.i.: (a) plant height; (b) reduction of leaf size and (c) type and severity of leaf symptoms. Pathotype I isolates (e.g. RT88) induced mild symptoms including mosaic and mottling; plant height and leaf size were not affected. Pathotype II isolates (e.g. RT138) induced mosaic, mottling and curling of the leaves, plant height and leaf size were slightly reduced compared with non infected plants. Pathotype III isolates (e.g. PV0420) induced severe mosaic, mottling, yellowing and etched rings on leaves and plants were dwarfed. Pathotype IV isolates (e.g. RT55) induced severe mosaic, mottling and necrosis at 14 d.p.i.;
the plants were severely dwarfed. The results, which are summarized in Table 4, show that the Asian and other CMV isolates vary in their biological diversity, especially in their ability to infect N. glutinosa.

答案和解析
在症状上的2个卓越的区别在孤立之中在系统主人N. benthamiana和N. tabacum Samsum NN未被观察. 然而,孤立能被分类入根据他们的能力的四pathotypes传染和导致在N. glutinosa的症状. 所有孤立能传染N. glutinosa,除了五从印度尼西亚收集了和二从印度,不是感染的在这个主人. 三个参量被评估了在14 d.p.i. : (a)株高; (b)叶子大小的减少和(c)叶子症状类型和严肃. Pathotype我孤立(即RT88)导致了温和的症状包括马赛克和呈杂色; 株高和叶子大小不受影响. 呈杂色和卷曲叶子,株高和叶子大小有一点减少了Pathotype II孤立(即RT138)导致的马赛克比较没被感染的植物. Pathotype III孤立(即PV0420)导致了严厉马赛克,呈杂色,染黄并且铭刻了在叶子的圆环,并且植物被变矮小了. Pathotype IV孤立(即RT55)导致了严厉马赛克,呈杂色和坏死在14 d.p.i.;
the植物严厉地被变矮小了. 结果,在表4被总结,特别是在他们的能力表示,亚洲人和其他CMV孤立变化在他们的生物差异,传染N. glutinosa.
