mpk6 mutant displays three different root phenotypes. The mpk6 mutant displayed three root phenotypes each related to the seed morphology: seedlings lacking PR (minus root; mpk6mr), seedlings with short roots (mpk6sr), and seedlings with PR longer than wild-type root (mpk6lr). (A) Proportion of 6 DAG seedlings in each mpk6 root mutant class.(B) PR length in 2 DAG wild-type (Wt) and the three mpk6 root mutant classes seedlings. Notice that in this developmental stage the root length of the later mpk6lr phenotype is similar to that of the wild-type. Error bars represent the mean±SE from data obtained from three independent experiments, each performed with 120 (A) or 100 (B) seedlings. Different letters on the bars indicate Tukey’s post-hoc test statistical difference at P≤0.001. (C) Seedlings lacking PR (minus root) developed from mpk6bs seeds (mpk6bs/mr); some of these seedlings were able to produce adventitious roots (white arrow). (D) Seeds at 6 DAG mpk6rs (rs/sr) and mpk6wb (wb/lr) develop shorter and longer PRs compared with the wild-type roots.
