Abstract

Abstract: Using potato (Solanum tuberosum) cultivar ‘Gannongshu 2’ as donor, 48 transgenic plants were obtained through an Agrobacterium-mediated transformation method using an RNAi vector containing an ADP-ribosylation factors (ARF) gene. Testing of the transformed plants on a culture media containing kanmycin and PCR assay showed that the AFR gene had been successfully integrated into the potato genome. The analysis of real time fluorescence quantitative polymerase chain reaction (qRT-PCR) data showed that the ARF gene expression declined to varying degrees in the transgenic plants compared with the controls, and interference degree reached 92.53% and 93.22% in the transgenic lines Z-11 and Z-12, respectively. The starch content of the transgenic plants increased by 4.29%-34.27%, the protein content by 1.47%-7.35%, the soluble sugar content by 1.44%-17.39%, and the sucrose content by 11.53%-53.84% compared with control plants; however, the glucose content of the transgenic plants decreased by 6.06%-21.21% compared with control plants.
