Abstract
Phototropins (phot) as a blue-light receptor regulate chloroplast movement, phototropism, stomatal opening, and leaf expansion. In previous studies, the velocity of the chloroplast avoidance response was limited by amounts of PHOT2 protein. To demonstrate a relationship between the blue light responses mediating by phot2 and expression level of PHOT2 protein, we prepared the CaMV35S::PHOT2-GFP transgenic lines under the Arabidopsis phot1phot2 double mutant. Therefore, several transgenic lines that showed different expression level of PHOT2-GFP protein were obtained. We will report the analysis of the blue light response in the transformants.
