a, Root length measurements for 7-day-old seedlings of the indicated genotypes. Box plots display 2nd and 3rd quartiles and the median, whiskers indicate maximum and minimum. Statistically significant differences (lower case letters) were determined by ordinary one-way ANOVA followed by Tukey’s test, two-sided, p < 0.0001. n = 8–15 independent biological replicates. b, Representative histological cross sections (toluidine blue-stained) from indicated genotypes. Orange arrowheads point out protophloem sieve element cell files.
