The relative expression of GmSPX-RING1 and P concentration in GmSPX-RING1-OE and GmSPX-RING1-RNAi transgenic hairy roots. a Relative expression of GmSPX-RING1 in GmSPX-RING1-OE and Control 1 transgenic hairy roots. b Relative expression of GmSPX-RING1 in GmSPX-RING1-RNAi and Control 2 transgenic hairy roots. c P concentration in GmSPX-RING1-OE and Control 1 transgenic hairy roots. d P concentration in GmSPX-RING1-RNAi and Control 2 transgenic hairy roots. GmSPX-RING1-OE: soybean transgenic hairy roots with GmSPX-RING1 overexpression vector, Control 1: soybean transgenic hairy roots with overexpression empty vector; GmSPX-RING1-RNAi: soybean transgenic hairy roots with RNA interference of GmSPX-RING1 vector, Control 2: soybean transgenic hairy roots with RNA interference empty vector. GmSPX-RING1-OE and GmSPX-RING1-RNAi hairy roots and their controls grown under +P or -P condition for 15d. Data were the mean values of biological replicates mean ± standard deviation (SD) (n = 3). Statistical significance was detected by a two-tailed t-test. * and ** significant at 0.05 and 0.01 probability levels, respectively
