自从1886年德国人A.马耶在荷兰提出烟草花叶病是由一种传染性的物质(后来称为病毒)所引起的以后,至今己历92年。在不到一个世纪的时间,人们通过研究,已经认识到许多重要的人畜病及农作物病都是由它引起的。尽管它微小到只能用百万分之一毫米的单位(nm=毫微米)来测量,但是人们还是逐步知道它的化学组成、结构以及生活方式和形态。近代,植物病毒学的研究,已经深入到探索生命机制、生命起源
It has been 92 years since German A. Mayer in the Netherlands proposed in 1886 that tobacco mosaic disease was caused by a contagious substance (later called a virus). In less than a century, people have come to realize through research that many important human diseases and crop diseases are caused by it. Although it is so small that it can only be measured in parts per million millimeters (nm = nm), its chemical composition, structure, lifestyle and morphology are gradually known. In modern times, the study of plant virology has gone deep into exploring the mechanism of life and the origin of life
