Exogenous 5-CHO-THF rescues the short primary root phenotype of atdfb. A and B, Seven-day-old seedlings of the wild type (WT) and atdfb germinated in solvent control and 500 μm 5-CHO-THF. Note that the primary root length of atdfb is restored to the wild type. Data are means from 18 to 25 roots ± se. Means with different letters are statistically significant (Tukey’s test, P < 0.05). C, QC organization in atdfb is also restored to wild-type patterns when grown on 500 μm 5-CHO-THF.
