Production and secretion of biologically active human granulocyte-macrophage colony stimulating factor in transgenic tomato suspension cultures.
A complementary DNA encoding human granulocyte-macrophage colony stimulating factor (hGM-CSF) was cloned and introduced into tomato (Lycopersicon esculentum cv. Seokwang) using Agrobacterium-mediated transformation. Genomic PCR and Northern blot analysis demonstrated the integration of the construction into the plant nuclear genome and expression of the hGM-CSF in transgenic tomato. The cell suspension culture was established from leaf-derived calli of the transgenic tomato plants transformed with the hGM-CSF gene. Recombinant hGM-CSF was synthesized by the transgenic cell culture and secreted into the growth medium at 45 microg l(-1) after 10 d' cultivation.
