PHO1 Antibody

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. PMID: 28943092
2. Genome-wide association mapping identified PHOSPHATE 1 (PHO1) and genes such as Root System Architecture 1 (RSA1) associated with differences in root allometry, a highly plastic trait capturing the distribution of lateral roots along the primary axis. PMID: 23980140
3. An important role of the EXS domain of PHO1 in a root-to-shoot signaling pathway linking phosphate deficiency response PMID: 26546667
4. AtWRKY42 modulated Pi homeostasis by regulating the expression of PHO1 and PHT1;1 to adapt to environmental changes in inorganic phosphate (Pi) availability. PMID: 25733771
5. PHR1 and PHO1 participate in the coregulation of Zn and Pi homeostasis. PMID: 24420568
6. Expression of PHO1 in guard cells of Arabidopsis thaliana is required for full stomatal responses to abscisic acid. PMID: 22612335
7. PHO1 can trigger Pi export in ectopic plant cells, strongly indicating that PHO1 is itself a Pi exporter. PMID: 22449068
8. PHO1 over-expression in the shoot of Arabidopsis thaliana led to a two- to threefold increase in shoot inorganic phosphate content and a severe reduction in shoot growth. PMID: 21309867
9. Reduction of PHO1 expression leads to wild-type growthof plants in phosphate-deficient media, despite Pi deficiency. PMID: 21288266
10. Our results demonstrate that WRKY6 and WRKY42 are involved in Arabidopsis responses to low Pi stress by regulation of PHO1 expression. PMID: 19934380
