a
Mutants are listed in alphabetical order to facilitate comparison with other tables in this article.
b
The numbers within parentheses are number of roots. ND, not determined.
c
Fifty mature hairs were assessed on each root, except rhd6, where three hairs were assessed on each root.
d
Ten mature hairs were measured on each root, except on rhd6, where two hairs were measured on each root. Wild-type length was ∼900 μm.
e
Multiple hairs that appeared at a single site of hair formation.
f
At least 1000 roots of each genotype were examined.
