High impact information on virH1

  • Ferulic acid was far more toxic than caffeic acid to the wild-type strain, although the wild-type strain was more resistant to ferulic acid than was the virH mutant [1].
  • One of these is the 2.5-kb virH locus, which was previously identified on the octopine-type Ti plasmid but thought to be absent from the nopaline-type Ti plasmid [2].
  • The virH operon contains two genes that resemble P-450-type monooxygenases [2].
  • The vir region covering 30.2-kb has found to be composed of 21 genes resembling virH1, virA, virB1-11, virG, virC1-2, and virD1-5 [3].
