Estimates of virus accumulation, virulence and seed transmission rate in vertically infected Cen-1 plants derived from the fifth vertical passage.

1Accumulation of virus RNA (µg/g fresh weight) estimated for 1∶1 mix of inoculated and systemically infected leaves.
2Effect of CMV infection on seed weight (SW) estimated as 1−(SWi/SWm), where i and m denote infected and mock-inoculated plants, respectively.
3Seed transmission rate was estimated as the number of infected seedlings out of 100 seeds.
Values are mean±standard error of the 5 lineages in evolved viruses and 10 replicates in non-evolved strains.

1. 病毒RNA积累量（微克/克鲜重）通过接种叶与系统侵染叶的1:1混合样本估算得到。
2. 黄瓜花叶病毒（Cucumber Mosaic Virus）侵染对种子重量（SW）的影响以公式1−(SWi/SWm)计算，其中i与m分别指代病毒侵染植株与模拟接种对照植株。
3. 种子传毒率以每100粒种子中出现侵染幼苗的数量进行估算。
所有数值均以均值±标准误呈现：进化病毒组取5个谱系的统计结果，非进化病毒株系则基于10次生物学重复计算得到。
