Expansin is a protein super family consisting of 4 families in vascular plants. Expansions are cell wall proteins which mediate acidic cell wall loosening through breaking hydrogen bonds between cellulose and glycan matrix. In this study, a construct named pbiexpa1 containing nptii and AtEXPA1 genes under the control of CaMV35s promoter was designed and fabricated. Arabidopsis plants were then transformed by pbiexpa1. Transformation was done by floral dip which did not need any tissue culture process. Transformed seedlings were able to remain green on MS medium containing 50mg/L kanamycin. Transgenic plants were confirmed by PCR and as expected two bands of 753 and 1080 bp were observed for transgenic plants. Keywords: Arabidopsis, Cell wall, Drought, Expansin Protein, Floral dip and AtEXPA1 ( ) #$ #*&'.!
