In order to explore the different genes related to low light tolerance between the the photosensitive and non-photosensitive varieties,stable genetic purple under the calyx,round eggplant inbred line Y5 and green under the calyx,round eggplant inbred line Y73 were sequenced at three-time points(0,4 and 8 h). The total effective data of 75.61 Gb was obtained,and the percentage of Q30 base reached 93.97%. 11 812 differential expression genes were obtained by sequencing and comparing two inbred lines at three-time points,including 5 277 up-regulated genes and 6 535 down-regulated genes. KEGG enrichment analysis of data at three time points shows three same pathways of phenylpropane biosynthesis,flavonoids biosynthesisand carbon fixation of photosynthetic organisms. There are four genes in the biosynthesis pathway of phenylpropane and flavonoids,named FAOMTCCOAOMTCYP73A4 and HST. The CHIANSF3HPAL genes and the transcription factor MYB113 gene related to anthocyanin synthesis were screened to express significantly in the peel under the calyx.
