Abstract

Abstract Objective A centrifugation-assisted peptide-mediated gene transfer (CAPT) method was recently developed as an efficient system for gene delivery into plant cells. However, the gene transfer efficiency of CAPT into plant cells was not entirely satisfactory for detecting transient expression of a transgene driven into mitochondria. Here, we report a new gene delivery system using a method called particle bombardment-assisted peptide-mediated gene transfer (PBPT). Results We investigated various parameters of the PBPT method to increase transient gene expression efficiency in Brassica campestris. The optimal conditions for PBPT were a single bombardment with gold particles coated with a DNA‒peptide complex (6 µg of DNA and 2 µg of peptide) at an acceleration pressure of 5 kg/cm2 and a target distance of 12.5 cm. Moreover, bombardment under the optimal conditions successfully transferred the transgene into the cells of other plant species, namely B. juncea and tomato. Thus, we developed a PBPT method for highly efficient delivery of a DNA‒peptide complex into plant mitochondria.
