Table 2 Persistence of soybean mosaic virus in A. rhizogenes-induced soybean hairy roots after one (2 weeks in culture) and two (4 weeks in culture) transfers, as measured by infectivity tests

From: Agrobacterium rhizogenes-induced soybean hairy roots versus Soybean mosaic virus (ARISHR-SMV) is an efficient pathosystem for studying soybean–virus interactions

  1. Each data point represents total number of plants from two replications
  2. aInfectivity was determined based on the number of infected plants/total number of plants inoculated
  3. bAverage  % infection of every transfer for each SMV strain
  4. cAverage  % infection of two transfers for each SMV strain
