植物病毒由蛋白外壳和核酸芯子组成。病毒的抗原活性部分是它的蛋白质,特别是包围核酸的蛋白外壳。大多数植物病毒的蛋白外壳由许多外形相同的亚基组成,具有相同的抗原性。大多数血清学试验取决于病毒,而感染力试验 The plant virus consists of a protein shell and a nucleic acid core. The antigenic part of the virus is its protein, particularly the protein envelope that surrounds the nucleic acid. The protein shell of most plant viruses consists of many identical subunits with the same antigenicity. Most serological tests depend on the virus, while the infectivity test
