Abstract:

To extract the statistical features of complete tobacco streak virus genome and conduct cluster analysis. In the tobacco streak virus complete genome sequence of the base, with two bases of each base and its subsequent posed by the three base groups, arranged in a new sequence S; the calculation of all 64 kinds of different groups in the three bases appear on the probability of S, we obtain a 64-dimensional vector L; Comparison of L-vector of each genome, we get 6 three base groups that emergence of probability are significantly different 6 three-base group （AAG；AGA；TGA；GAC；GAG；GTT）the emergence of probability and the genome associated with genetic variation has importance; 4 different sources Tobacco streak virus complete genome, based on the results of their genetic variation, form 2 major categories.
