AM phenotype of a Rht₁/Rht₂ dominant DELLA dwarf wheat line colonized by G. versiforme. (A) Level of colonization of the Rht₁/Rht₂ dominant DELLA dwarf and rht₁/rht₂ wild type at 31 d.p.i. The Rht₁/Rht₂ line differs significantly from the rht₁/rht₂ wild-type line. Data are averages ± SEM (n = 3, where N denotes the number of independent root samples). (B–D) Gene expression of G. versiforme α-tubulin (GvTUB) (B) and the phosphate transporters TaPT10 (C) and TaPT11 (D) in dwarf and wild-type roots at 31 d.p.i. relative to the Triticum aestivum ADP ribosylation factor (ADP-RF) assayed by quantitative RT-PCR. TaPT10 and TaPT11 transcript levels are significantly higher in the dwarf than in the wild-type roots. Data are averages ± SEM (n = 3, where N denotes the number of independent root samples). (E) Phosphorus content in shoots of noncolonized (−AMF) and colonized (+AMF) dwarf and wild-type plants at 13 wk post inoculation (w.p.i.). Data are averages ± SEM (n = 4, where N denotes the number of independent plants). DW, dry weight. (F) Shoot fresh weight (FW) of noncolonized and colonized dwarf and wild-type plants at 13 w.p.i. Data are averages ± SEM (n = 4, where N denotes the number of independent plants). *P ≤ 0.05.
