The Pi contents and the expression of PSR genes in PalERF2 transgenic and WT poplars. (A) The Pi contents in WT and transgenic plants before drought treatment. (B) The Pi contents in WT and transgenic poplars after drought treatment. (A,B) Error bars indicate SD values from three biological replicates. Significant difference was analyzed by Duncan’s test (p < 0.05, n = 5). Different letters indicate statistically significant differences. (C) The qRT-PCR analyzed the relative expression of PSR genes in WT and transgenic poplars after drought treatment. Error bars indicate SD values from three biological replicates.
