Table 2 Genetic variation in SbDV-MD6 populations in different host species and passages

From: Aphid vectors impose a major bottleneck on Soybean dwarf virus populations for horizontal transmission in soybean

Host and passage Mutated clones Total mutations/ bases sequenced Mutation frequency (%)
Clover 60% (6/10) 25/29, 590 0.08a
Pea and passage 1 55% (11/20) 66/59, 180 0.11a
Pea and passage 8 40% (8/20) 64/59, 180 0.10a
Soybean and passage 1 56% (10/18) 64/53, 262 0.12b
Soybean and passage 6 44% (8/18) 53/53, 262 0.10a
  1. Substitutions are counted for determining mutation frequency. Mutation frequencies with the same letter were not statistically different. Least significant differences were determined by the ANOVA test (P < 0.05)
