OsAUX1 promotes root hair growth at low external P levels. a 9-day-old WT, osaux1-1;1and osaux1-1;3 seedlings were grown for 6 days in hydroponics at three different P concentrations. Scale bar 1 mm. b Quantitation of RH length in WT, osaux1-1;1and osaux1-1;3 mutants reveal low P. Each bar represents the average length of 30–60 fully elongated RH on >10 nodal roots. *, **, and *** indicate significant difference p value <0.05, 0.001, and 0.0001, respectively. Error bars mean ± SE, n = three biological replicates and p values were calculated by Student’s t test
