Light intensity dependent root growth varies in phytochrome mutants. a Phenotypic differences in root architecture. b Primary root length (mm) for WT, phyB-9 and phyA-211 under four different WL intensities of 38, 75, 112 and 150 μmol m ^− 2 s ^− 1. The analysis was done in 6-days old seedlings. Error bars represent SE. The means were compared using Tukey test with p ≤ 0.05. Same letters denote statistical significance. There were five technical replicates, each replicate consists of 20 seedlings. Scale bar = 10 mm
