Approaches enabling efficient phosphorus utilization in crops are of great importance. In cereal crop like wheat, inorganic phosphate (Pi) is high and mature grains the major sink for Pi storage. Research that addresses importance homeostasis developing limited. an attempt to understand wheat grains, we identified twelve new transporters (PHT), these phyologentically well distributed along with members reported from Arabidopsis rice. Enhanced expression PHT1-subfamily genes was observed roots subjected starvation suggesting their active role homeostasis. Differential patterns all PHT during grain filling stages suggested filial tissues. Additionally, accumulation total P aleurone correlates TaPHTs other related genes. Tissue specific transcript TaPHT1.1, TaPHT1.2, TaPHT1.4 aleurone; TaPHT3.1 embryo TaPHT4.2 endosperm observed. Furthermore, abundance affected low phytate grains. Altogether, this study helps expanding knowledge prioritize candidate Pi-transporters modulate
