Comparative analysis of root growth in G. hirsutum and G. arboreum. a Representative roots from 7-d-old G. hirsutum and G. arboreum seedlings. Bar = 5 cm. b Root lengths of 7-d-old G. hirsutum and G. arboreum seedlings as shown in (a). Statistical analysis was carried out on three independent experiments. A total of 10 seedlings were used for each measurement. Root lengths are shown as means ± SE. c Quantitative RT-PCR analysis of PIN genes in 7-d-old G. hirsutum and G. arboreum roots
