Description
PHO1 Gene Family and PHO1;H9
The PHO1 gene family in Arabidopsis thaliana comprises 11 members (PHO1 and PHO1;H1 to PHO1;H10), all sharing homology with the original PHO1 gene (AT3G23430) .
Key Features of PHO1;H9 (AT3G29060):
-
Structure: Contains hydrophilic N-terminal and membrane-spanning C-terminal domains, characteristic of the PHO1 family .
-
Expression: Restricted to floral tissues, with promoter-GUS assays showing activity in pollen grains .
-
Function: While PHO1 itself facilitates phosphate (Pi) transfer to the xylem, functional redundancy among homologs is limited; PHO1;H9’s role remains uncharacterized .
Table 1: Arabidopsis PHO1 Gene Family
| Gene Name | Locus ID | Expression Profile | Known Function |
|---|---|---|---|
| PHO1 | AT3G23430 | Roots, stelar cells | Pi loading into xylem |
| PHO1;H9 | AT3G29060 | Flowers (pollen grains) | Undetermined |
| PHO1;H1 | AT1G68740 | Leaves, roots | Weak Pi transport activity |
| PHO1;H3 | AT1G14040 | Roots, stems | Modulates Pi homeostasis |
