Abstract: Phosphorus (P) is an important macronutrient with critical functions in plants. Phosphate (Pi) transporters, which mediate Pi acquisition and Pi translocation within the plant, are key factors in Pi deficiency responses. However, their relevance for adaptation to long‐term Pi limitation under agronomic conditions, particularly in wheat, remains unknown.Here, we describe the identification of the complete Pi transporter gene family (Pht1) in wheat (Triticum aestivum). Gene expression profiles were compared for … Show more

“…AtPHO2 has been shown to be involved in the regulation of PHT1 genes such as AtPHT1.8 and AtPHT1.9 in Arabidopsis [10,11] and OsPHT1.2 and OsPHT1.8 in rice [12]. In rice, the kinetics of two Pi transporter genes have been investigated in detail classifying Ospht2;1 as a low-affinity and OsPht6.1 as a high affinity transporter [13] and the induction of OsPht6.1 by Pi starvation was subsequently confirmed in independent studies in rice and wheat [14,15]. Such Pi-starvation induced genes are thus robust molecular indicators of the Pi-starvation response in plants and might be useful to assess the effect of plant growth promoting bacteria (PGPB).…”

“…Under conditions of P deficiency, enhanced expression of high affinity phosphate transporters/carriers was shown to increase P i uptake (Bucher ; Chiou & Lin ; Kavka & Polle ; Grün et al . ; Ham et al . ).…”

“…It is worth to note that apart from its role in Pi uptake, TaPHT2.1 was functionally characterized as an important P signalling component involved in Pi translocation from cytosol to chloroplast in Pi-stressed leaves ( [41] [20,44]), there is no detail on their precise biological role in wheat tissues/cell. In addition, recent expression profiles of wheat PHT1 sub-family genes during hydroponic and field-grown plant tissues were correlated with the presence of cis-acting promoter elements ( [22]). These studies showed growing interests in the crop Pi-transporters among researchers.…”

“…Numerous Pi transporters have been identified in wheat [20][21][22] Gradual elucidation of these components and their roles have been effectively achieved through experiments either increasing P remobilization from senescing tissue or reducing the partition of P to developing grains [23]. However, initial identification of these transporters were generated from data collected for those of the model plant Arabidopsis [24].…”
