摘要
Gradual progress made in genetic transformation of wheat is presented in this paper. Information on promoters, antibiotic, herbicide and auxotrophic markers, and various traits of wheat modified through genetic transformation, is provided. In addition the methods used for wheat transformation are discussed. Though significant efforts have been made for genetic transformation of wheat mainly through particle bombardment method but transformation efficiency is still low for mass production of fertile transgenic plants. Studies on the inheritance of transgenes and its incorporation into commercial elite cultivars are not significant. Agrobacterium mediated transformation seems to have better prospects for wheat transformation in future due to its advantages over particle bombardment. In planta transformation of wheat tissues seems possible only with Agrobacterium.
