Figure 4. TMTM contributes positively to root growth. Wild-type
(A) or slim1 (B) seedling root growth on high sulfate medium (HS)
or on low sulfate medium (LS) with addition of 0, 100 or 1000 μg TMTM was measured 7 days after application. Error bars represent SEs from at
least 6 independent biological replicates for wildtype and 8 biological
replicates for slim1 . Statistical significance was determined by
Duncan’s multiple range test with p-vale < 0.05, and indicated
with lower-case letters.
