High impact information on IAA8

  • Auxin-induction of two late genes, IAA7 and IAA8, is inhibited by cycloheximide, indicating requirement of protein synthesis for their activation [1].
  • The vascular expression pattern of the IAA8 promoter in leaves mirrors the developmentally regulated auxin gradient in expanding leaf blades [2].
  • IAA8 expression during vascular cell differentiation [2].
