| Abstract: |
| Plant genetic transformation technology aims to enhance crop traits, thereby yielding new varieties with high yield, superior quality, and multiple resistances. Traditional genetic transformation methods face certain limitations, such as genotypic restrictions, susceptibility to tissue damage, and tedious tissue culture processes. Pollen-mediated genetic transformation, with its advantages such as shorter transformation duration and simplicity, has drawn widespread attention. Meanwhile, nanomaterials exhibit significant potential in delivering nucleic acid molecules into plant tissues, including pollen. This review summarizes recent advances in nanomaterial-mediated delivery of nucleic acid, highlights the research and application of nanomaterials in pollen-mediated plant genetic transformation, and points out the future development in this field. |
