Twelve genes of the PIN family in rice were analyzed for gene and protein structures and an evolutionary relationship with reported AtPINs in Arabidopsis. Four members of PIN1 (designated as OsPIN1a–d), one gene paired with AtPIN2 (OsPIN2), three members of PIN5 (OsPIN5a–c), one gene paired with AtPIN8 (OsPIN8), and three monocot-specific PINs (OsPIN9, OsPIN10a, and b) were identified from the phylogenetic analysis. Tissue-specific expression patterns of nine PIN genes among them were investigated using RT–PCR and GUS reporter. The wide variations in the expression domain in different tissues of the PIN genes were observed. In general, PIN genes are up-regulated by exogenous auxin, while different responses of different PIN genes to other hormones were found.

Key Words: Oryza sativa L. • PIN family • expression pattern
