Research Abstract

Cell-type specific RNA was extracted with Lasermicrodissection and used for microarray analysis. In this study, expression and functional analyses of cell-type specific MATE transporters in the nodules were performed. LjMATE1 was expressed in the infection zone of nodules and found to transport citrate for Fe translocation to the infection zone of nodules. LjMATE2 was expressed highly in the anthocyanin-accumulating stems and found to be expressed at the tonoplasts. The expression of LjMATE3 was induced during nodulation and also by GSH in a similar way as genes involved in the flavonoid synthesis.
