%X In order to investigate the effect of different light intensities on the fruit coloration, the content of anthocyanin, and the relative xpression of anthocyanin biosynthesis related genes in <i>Fragaria&#215;ananassa</i> Duch. ‘Benihoppe’, we determined the content of anthocyanin using HPLC and analyzed the relative expression of anthocyanin biosynthesis related genes using quantitative real-time PCR under the light transmittance of 100%, 75% and 25%. The results showed that the content of strawberry under light transmittance 75% and 25% decreased 41.58% and 92.54%, respectively, compared with the control. The relative expression of anthocyanin biosynthesis related genes and transcription factors, <i>FaMYB</i>10 and <i>FaMYB</i>1, were also decreased. The expression of <i>FaDFR, FaF</i>3'<i>H</i> and <i>FaUFGT</i> were significantly correlated with the anthocyanin content. These results indicated that light was the key environmental factor affecting fruit coloring, and shading could inhibited the expression of anthocyanin biosynthesis related genes and transcription factors, blocked the anthocyanin synthesis in fruits, which finally contributed to the fruits coloring differences.
