Gene expression analysis on Hydrangea macrophylla sepal pigmentation due to aluminum accumulation

ABSTRACT: Most blue color in flowers is due to anthocyanin, and considerable proportion of blue coloration can be attributed to metal-complexed anthocyanins. Recently, we reported vacuolar localized iron-transporter in blue petal cells of Tulipa gesneriana. However the mechanism of another metal ion transporters and subsequent flower color development has yet to be fully explored. In Hydrangea macrophylla, Al3+ is involved in blue coloration and the anthocyanin is formed Al3+-complex in vacuoles. To identify the molecular mechanism of blue coloration in hydrangea flowers, we tried to isolate the related genes transporting metal ion into vacuoles. From the sepal cDNA library we read the sequences of ca. 12000 genes, then a microarray analysis was carried out. From the sequences information, we chose
