Figures & data
Figure 1. Excision induced lateral root formation in tomato. (A) The root tips were excised from the seedlings at 4 DAG and seedlings were photographed at 7 DAG. (B) The root tips were excised either at 2 DAG or 4 DAG and number of lateral LRF was counted at 7 DAG. The control refers to intact seedlings. (n ≥ 10 ± SE) (C) The root tips were excised at 2 DAG from DR5::GUS transgenic seedlings. The roots were stained for GUS activity 24 h post-excision. (i) Intact roots at 2 DAG (ii) Root tip-excised roots after 24 h (iii) Intact seedling root at 3 DAG.
Figure 2. Effect of ethylene and light on LRF. (A) The root tips were excised at 2 DAG and at the same time 20 μM ACC was supplemented to the germination boxes. The LRF was counted at 7 DAG. (n ≥ 10 ± SE) (B) The cotyledons or whole shoot was excised from seedlings at 2 DAG either with or without root tip excision. The LRF was counted at 7 DAG. The seedling with intact roots served as a control. (n ≥ 10 ± SE) (C) Effect of red (R), or far red (FR), and white light (WL) was examined after excision of root tips at 2 DAG or 4 DAG. The LRF was counted at 7 DAG. (n ≥ 10 ± SE).
