Altered sulphate deficiency stress response in lateral root development in axr1. LR, lateral roots; LRP, lateral root primordia. Density is expressed as the average number of LR or LRP on per cm primary root (PR), with the SD bars shown. (A) Seedlings were transferred to and grown vertically on the agar-solidified medium for 10 d after 5-d vertical growth on the normal, solidified medium (n=4–5). (B) Seedlings were continuously grown for 5 d in liquid medium (n=16). Different letters (uppercase letters for the LR density, and lowercase letters for the LRP density) above the columns indicate statistically significant difference (P=0.05)
