| Abstract: | The plant expression vector pUBTB harboring CrylAb gene drivered by UBI promoter was constructed and introduced into sugarcane by Agrobatorium-mediated transformation, and 67 transformed plantlets were survived after three times successive PPT selection. These plantlets were detected by PCR and 22 plantlets showed positive. Furthermore, seven PCR positive plantlets were also detected by RT-PCR. The results showed that the foreign gene had been integrated into sugarcane genome and expressed. |
