Polar auxin transport gene PIN (PIN-FORMED) determines the concentration gradient of auxin and plays an important role in development and secondary metabolism of plants. This study was designed to analyze the bioinformatics and expression of the PIN genes in Panax ginseng to explore a novel way of breeding ginseng varieties. Heatmap and cluster analysis of PIN2, PIN3, PIN6 was performed in four-year-old Jilin ginseng. Sequence homology alignment, RT-PCR amplification, sequencing and bioinformatics analysis were used to identify three PIN family genes PgPIN2, PgPIN3 and PgPIN6 in P. ginseng. PIN expression in ginseng adventitious root and culture seedling was analyzed with qRT-PCR technique. Results suggested that in ginseng adventitious root tip, PgPIN3 and PgPIN6 exhibited a high level of expression; in ginseng culture seedling root, PgPIN2 showed a high level of expression; in four-year-old Jilin ginseng at the fruit ripening stage, PgPIN2 and PgPIN6 were highly expressed in root and rhizome, while PgPIN3 had a high level in ginseng leaf, fruit and root. Tissue specific expression profile showed that PgPIN2 and PgPIN6 probably were involved in the development and tropism growth in ginseng roots, while PIN3 might be in relation to the growth and development of the aerial part of plants.
