Gene Details:

• Gene ID:
• Gene Symbol: TaPHT2|1
• Gene Name: phosphate transporter 2-1
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Function of wheat phosphate transporter gene TaPHT2|1|TaPHT2|1 in Pi translocation and plant growth regulation under replete and limited Pi supply conditions.
• Expression analysis revealed that TaPHT2|1|TaPHT2|1 was strongly expressed in the leaves, was up-regulated by low Pi stress, and exhibited a circadian rhythmic expression pattern. TaPHT2|1|TaPHT2|1–green fluorescent protein fusions in the leaves of tobacco and wheat were specifically detected in the chloroplast envelop.
• The down-regulated expression of TaPHT2|1|TaPHT2|1 resulted in reduced photosynthetic capacities, total P contents, and accumulated P amounts in plants under sufficient and deficient Pi conditions, eventually leading to worse plant growth phenotypes.
• The TaPHT2|1|TaPHT2|1 knockdown plants exhibited pronounced decrease in accumulated phosphorus in sufficient and deficient Pi conditions, suggesting that TaPHT2|1|TaPHT2|1 is an important factor to associate with a distinct P signaling that up-regulates other PT members to control Pi acquisition and translocation within plants.
• TaPHT2|1|TaPHT2|1 is a key member of the Pht2 family involved in Pi translocation, and that it can function in the improvement of phosphorus usage efficiency in wheat.
