Abstract:
PtAUX1 vector constructed by our laboratory were transformed into Poplar,then get transgenic plants.The transgenic plants were contected by PCR,and the phenotypes were analyzed in the different illumination length and illumination intensity.The results showed that the transgenic plants influenced the sensitivity of light,leaves were curling in the low light intensity.These results indicated that PtAUX1 influence auxin polar transport by nonuniform distribution of import carrier,then participated in leaf polarity establishment,and influenced morphology and development of the organs.
