Gene Details:

• Gene ID: Zm00001eb295490
• Gene Symbol: ZmPHO2 PHO2 uce10
• Gene Name: Phosphate 2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Knockout of ZmPHO2 (Phosphate 2), a miR399 target, resulted in a similar premature senescence phenotype.
• Our study reveals a direct functional link between Pi-deprivation sensing by the miR399-ZmPHO2 regulatory module and plant developmental regulation by ID1.
• INDETERMINATE1 autonomously regulates phosphate homeostasis upstream of the miR399-ZmPHO2 signaling module in maize.
• ZmPHO2 was under selection during maize domestication and cultivation, resulting in a more sensitive response to Pi starvation in temperate maize than in tropical maize.
• Knocking out ZmPHO2, a miR399 target, results in premature senescence.
• ZmPHO2 ortholog of Arabidopsis Ubiquitin-conjugating E2 family protein that is involved in phosphate starvation response.
