摘要: A positive selection system was developed for Agrobacterium-mediated transformation of rice that does not use toxic Compounds such as antibiotics or herbicides. The selection system is based on the Escherichia coli phosphomannose isomerase (pmi) gene as a selectable marker and mannose as the selective agent. Only transgenic plants were able to metabolize mannose into a usable Source of carbon, fructose. Selection was achieved using a combination of mannose and sucrose at 10 g/L and 5 g/L, respectively. Transgenic rice plants were produced efficiently in japanica rice variety Zhonghua 8, with transformation frequency of 16.5%, which was slightly lower than that achieved by hygromycin selection.
