Expression of PHT1 genes is altered in GPLα-modified lines. a Expression of the nine PHT1 family genes in two independent GPLα-overexpressing transgenic and wild type [WT (Col)] plants under Pi-deficient growth conditions. b Expression of PHT1;1, PHT1;2, PHT1;3, and PHT1;4 in transgenic lines with modified GPLα expression under Pi-deficient conditions including GPLα-overexpressing lines GPLα–OE1 (Col-0 background) and GPLα–OE3 (Ler background); GPLα-suppressed lines GPLα–SI1 (Col-0 background) and GPLα–SI3 (Ler background). Expression was measured by qRT-PCR and represents the mean of three biological repeats. Different letters above the columns indicate significant differences within each specific gene triplicate measured in a and within each gene triplicate for a given ecotype in b (P < 0.05, ±SD)
