Fig 1. Effects of rosmarinic acid on root morphology of A. thaliana.

Fig 1

A) Primary Root Length (PRL), B) Total Root Length (TRL), C) Number of Lateral Roots (NLR), D) Lateral Roots Length (LRL), E) Root Hair Length (RHL), and F) Root Hair Density (RHD) of Arabidopsis seedlings treated with different concentrations (0–1200 μM) of RA, for 14 days. On the bottom the effects of different RA concentrations on root anatomy are reported. Data are expressed as percentage of the control. Different letters indicate significant differences among treatments at P ≤ 0.05. N = 4.
