利用透射电镜观察了水稻栽培期间日本某稻田长期施肥试验积水中病毒群落衣壳大小的分布。衣壳尺寸呈单相分布，中位数在50 ~ 70 nm范围内。大多数样品的四分位数区间从40-50 nm或50-60 nm缩小到60-70 nm或70-80 nm。病毒群落衣壳大小分布没有明显的季节变化。不同肥田间的大小分布也没有差异。洪水中的病毒群落以等长二十面体形式为主。具有八面体衣壳和细长衣壳的病毒在洪水中是罕见和零星的。(C) 2007 Elsevier Ltd.版权所有。
Capsid size distributions of viral communities in the floodwater of a Japanese paddy field under a long-term fertilizer trial were surveyed during the rice cultivation period by using transmission electron microscopy. The capsid size distributions were monophasic, and the median values fell within the range of 50-70 nm. The quartile intervals were narrow from either 40-50 nm or 50-60 nm to either 60-70 nm or 70-80 nm for most samples. There was no clear seasonal variation in the capsid size distribution of viral communities. The difference in size distributions among different fertilizer plots was also not found. Viral communities in the floodwater were predominated by isometric icosahedral forms. Viruses with octahedral capsids and elongated ones were rare and sporadic in the floodwater.
