Due to the complexity of genome background in sugarcane,gene trangsformation has been one of the most useful ways for sugarcane genetic improvement.But low efficiency and instablility are the major problems for gene transformation in sugarcane.After years of sugarcane transformation research,a fast and efficient gene transformation system has been developed in our lab.20% of transformation efficiency,90% of selection efficiency and only four months of transformation duration make it a low cost transformation approach.
