<p>This part has been used as a reporter for observation of bacterial uptake into the roots of the plants. Due to its photoconvertible properties, it allows to monitor the metabolic activity of the bacterial cell once uptaken into the root. Dendra was converted from 486nm excitation and 505nm emission wavelength, to 558nm excitation and 575nm emission wavelength using single photon stimulation. Conversion was achieved after exposure to 405nm wavelength using laser. Photoconversion was completed after about 15 rounds of bleaching at 50% laser intensity with the pinhole set to 3 airy units.</p>

The main goal of this characterization is to find out which pH value is the most effective among the 6 pH values in order to obtain a suitable culture condition for the expression of Dendar2.We further found that the part which expressed the protein Dendar2 worked well in E.coli strain DH10B, like in the DH5 alpha.

Result and Findings

1.pH 4.5 is found to be the best pH that is suitable for the expression of Dendar2 .

2.Thered fluorescence from Dendar2 after photoconversion showed stronger fluorescent intensity than before.

3.Compared with the the expression pattern of Dendar2 as showed previously in DH5α, we concluded that the expression of Dendar2 works in both E.coli strains.
