SA facilitates the P translocation under P-insufficient condition in rice. Root and shoot total P content (A and B), xylem P content (C) and the relative expression of P related transporter genes were detected. Data are means ± SD (n = 4). Different letters represent significant differences by Duncan’s multiple range test at the P < 0.05 and asterisks indicate a significant difference at P < 0.05 by Student’s t test
