Fig. 1.
Sand plates supported DNRR. (A) Image of explants on an agar plate contaminated with bacteria. (B) Explants on a sand plate at 10 DAC. (C) Adventitious roots (arrows) formed at cutting site of explants on sand plates. (D) Comparison of rooting ratio between Col-0 explants on phytagel plates and sand plates. Data are mean±s.e.m. (E) Rooting ratio of Col-0 and yuc1D at 10 DAC on sand plates, each dot represents the rooting ratio of an independent experiment with 20 explants. *P<0.01 (unpaired two-tailed Student's t-test). Data are mean±s.e.m. (F) A comparison of adventitious root number formed on Col-0 and yuc1D on sand plates. Numbers indicate the number of adventitious roots from each explant. *P<0.01 (Mann–Whitney test). Scale bars: 1 cm in A,B; 5 mm in C.
