Abstract
Genetic transformation of sugarcane has a tremendous potential to complement traditional breeding in crop improvement and will likely transform sugarcane into a bio-factory for value-added products. We describe here Agrobacterium tumefaciens-mediated transformation of sugarcane. Embryogenic callus induced from immature leaf whorls was used as target for transformation with the hypervirulent Agrobacterium strain AGL1 carrying a constitutive nptII expression cassette in vector pPZP200. Selection with 30 mg/L geneticin during the callus phase and 30 mg/L paromomycin during regeneration of shoots and roots effectively suppressed the development of non-transgenic plants. This protocol was successful with a commercially important sugarcane cultivar, CP-88-1762, at a transformation efficiency of two independent transgenic plants per g of callus.
