Complete genome sequences of 20 viruses in Bunyaviridae loaded from NCBI were analyzed by two biological softwares of DNAMAN and DNASTAR. The results indicated great variability in both nucleic acid sequence and protein structure between plant viruses and animal viruses:(1) only plant viruses could encored NSm in M genome;(2) the length of nucleic acid sequence and protein sequence was different;(3) GC content of nucleic acid of animal viruses was higher than plant viruses of that;(4) protein topology analysis by online software SMART discovered that there was significant difference for the structure of glycoproteins G(subscript nG between animal-infecting and plant-infecting viruses;(5) usually, protein of plant-infecting virus had more complicated structure, more low compositional complexity and had N-Signal peptides except INSV.
