  • Length of the primary root and number of developing lateral roots in Arabidopsis seedlings collected at different DAG. Lateral roots (LR) and lateral root primordia (LRP ≥ V) were counted and classified according to Malamy and Benfey (1997). Values (means ± sd) were calculated from measurements of 50 seedlings.
