GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. The Arabidopsis Pi exporters PHO1 and PHOH1 are expressed in the chalazal seed coat (CZSC) of developing seeds. PHO1 is additionally expressed in developing ovules. Phosphorus (P) content and Pi flux between the seed coat and embryo were analyzed in seeds from grafts between WT roots and scions from either pho1, phoh1, or the pho1 phoh1 double mutant.

  2. Although transfer of Pi to the root xylem vessel is primarily mediated by PHO1, this homologue also contributes to Pi loading to the xylem. The two genes are regulated by Pi deficiency by distinct signal transduction pathways.
