Table I. TPs differentially expressed in roots and leaves due to Pi deficiency

TPs with altered expression patterns between Pi-sufficient and Pi-deficient roots and leaves (PdCR versus PsR and PdL versus PsL) were used. The numbers of individual transcripts annotated as a member of each TP family exhibiting increased or decreased expression (2-fold or greater change) in Pi-deficient tissues compared with Pi-sufficient tissues are shown. ABC, ATP-binding cassette; PIP, plasma membrane intrinsic protein; TIP, tonoplast intrinsic protein.
