Root growth of PUKI and PUMY expression variants.
(A) Comparison of root growth in the wild type, PUKI mutants, and PUKI c/oe. At 6 dai, germinated seedlings were placed on horizontal plates containing half-strength MS medium (without salt) and root lengths were determined daily up to 17 dai. Error bars are sd (n = 9 seedlings per genotype in groups of three on three different plates).
(B) Same as in (A) but for different PUMY expression variants.
