Application of multigene expression vector containing transformation-competent artificial chromosome and agrobacterium-mediated transformation for studying their effects on rice

By using a transformation-competent artificial chromosome vector pYLTAC747H,we constructed four genes relating to assimilation translocation,including OsSUT5,OsMST4,OsCIN3 and OAAT in the expression vector,pTAC747H-OAAT-SUT5-CIN3-MST4.The entire inserted fragment was approximately 30 kb.By the agrobacterium-mediated transformation,7 independent clones were obtained.PCR detection showed that 4 target genes and one marker gene had been integrated into the rice genome.
