High impact information on OBP2

  • RNA interference-mediated OBP2 blockade leads to reduced expression of CYP83B1 [1].
  • In addition, auxin concentration is increased in leaves and seedlings of OBP2 over-expression lines relative to wild-type, and plant size is diminished due to a reduction in cell size [1].
  • OBP2 expression is induced in response to a generalist herbivore, Spodoptera littoralis, and by treatment with the plant signalling molecule methyl jasmonate, both of which also trigger IGS accumulation [1].
  • Two additional Dof proteins, called OBP2 and OBP3, were isolated through homologous screening [2].
