Current Projects

  • Study the role of a novel SANT/MYB-like gene (LeFSB1) in mediating tomato fruit development.
  • Induction of transgenic parthenocarpy in tomato, strawberry and melon via altering auxin biosynthesis (iaaM & iaaH) or auxin signal transduction (rolB) specifically in the ovary.
  • Characterization of reproductive organ (ovary, stamens or petals) specific genes and promoters.
  • Drought tolerance via modulation of fatty acid desaturation
