The production of therapeutic proteins for human diseases in plants results in many economic benefits, including reduced risk of animal virus contamination, high yields, and reduced production and storage costs. Human cytokines, interleukin-11 (hIL-11) and granulocyte-macrophage colony-stimulating factor (hGM-CSF), cDNAs were introduced into rice or tobacco, using either the maize ubiquitin promoter or the 35S promoter. The primary hIL-11 transgenic rice plants exhibited stunted growth and a sterile phenotype, whereas the hIL-11 transgenic tobacco plants did not. This suggests that hIL-11 expression in rice disrupts the normal growth and development of the plant. The regeneration efficiency of rice calli transformed with hGM-CSF was found to be approximately a quarter of that seen with the hIL-11, suggesting that hGM-CSF expression is more deleterious to the regeneration of rice calli than is hIL-11. However, the surviving hGM-CSF transgenic rice plants exhibited a normal phenotype of growth. Therefore, it appears that only those transgenic rice lines that expressed the human cytokines in small quantities were able to survive the selection process.
